4 BLOOD COMPONENTS
A
listing of the description, action, indications, side effects, dosage
and administration of blood components may be found in the "Circular
of Information for the Use of Human Blood and Blood Components and the
Circular for the Use of Cellular Therapy Products." This circular is
available on patient care units, and may also be obtained from the Blood
Bank. The label of each component, except Cryoprecipitated Antihemophilic
Globulin, contains the anticoagulant or preservative solution used for
that component. A description of the various anticoagulant and preservative
solutions for blood components may be found in Appendix B. A list of
component abbreviations used on the patient's medical record may be
found in Appendix C. If additional information is required, please consult
the Blood Bank medical or supervisory staff. Not included in this chapter
are peripheral blood progenitor cells or bone marrow used solely for
bone marrow transplantation purposes.
Beginning
May 1, 2006, requests for CMV seronegative blood components will be
filled with prestorage leukocyte-reduced blood components. 5/1/06
Red Cell Components
WHOLE BLOOD
| This component is not available. Requests for Whole
Blood will be referred to the Blood Bank Medical Staff for review. When
exchange transfusion of a neonatal patient is required, the Blood Bank
will provide Red Blood Cells resuspended in Fresh Frozen Plasma. |
RED BLOOD CELLS, Leukocyte-Reduced
| Crossmatch: |
Required |
| Approximate Volume: |
340-400 mL AS-1 or AS-3 Additive
sol.
200 mL ACD-A Apheresis |
| Outdate: |
42 days (AS-1 or AS-3 additive solution)
35 days CPDA-1
21 days ADC-A |
| Hematocrit: |
55-65 % Additive solutions
70-80 % CPDA-1
56-59% ACD-A Apheresi |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
20 minutes |
| Dose Adult: |
1 unit per 1 gm Hgb rise desired |
| Pediatrics: |
5-15 mL/kgm body weight |
| Description: Contains
red cells from one unit of whole blood plus a small amount of plasma
and anticoagulant, and for AS-1 and AS-3 and AS-5 units, approximately
110 mL of additive solution. Apheresis Red cells contain red cells,
and either anticoagulant ACD-A or sodium citrate. The transfusion
of one unit of red cells is expected to increase the hemoglobin
1-1.5 g/dL in the 70 kG patient. All Red Blood Cells routinely issued
have reduced leukocyte content through prestorage filtration by
our blood supplier. Such processing reduced the risk of CMV transmission,
febrile transfusion reactions and platelet transfusion refractoriness.
Beginning May 1, 2006, requests for CMV seronegative
blood components will be filled with prestorage leukocyte-reduced
blood components. 5/1/06 |
| Indications: Patients whose symptomatic deficit of oxygen carrying
capacity cannot be corrected by alternative therapy. A hemoglobin or hematocrit
should be measured before each transfusion except in the case of severe
hemorrhage. Usually indicated when the Hgb is <6 g/dL. Rarely indicated
when the Hgb is > 10 g/dL. |
RED BLOOD CELLS, Washed
| Crossmatch: |
Required |
| Appriximate Volume: |
220 mL |
| Outdate: |
24 hours after washing |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
12-24 hours. Longer time intervals will be necessary if the component
is ordered at night or on weekends. This component is ordered specially
from the blood supplier. |
| Dose Adult: 1 unit per 1 gm Hgb rise desired |
| Pediatrics: 5-15 mL/kgm body weight |
| Description: A unit of Red Blood Cells that has been washed
and resuspended in a saline solution. If RBC Washed are ordered for a patient
and subsequently canceled, Blood Bank personnel will attempt to allocate
the component to another patient |
| Indications::Prevention of severe allergic reactions
to plasma proteins, as for patients with anti-IgA antibodies. |
RED BLOOD CELLS, FROZEN DEGLYCEROLIZED
| Crossmatch: |
Required |
| Approximate Volume: |
200 mL |
| Outdate: |
24 hours after deglycerolization |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
12-24 hours. Longer intervals will be necessary if the component is ordered
at night and on weekends. |
| Dose Adult: 1 unit per 1 gm Hgb rise desired |
| Pediatrics: 5-15 mL/kgm body weight |
| Description: A unit of Red Blood Cells that was once frozen
in glycerol and has subsequently been thawed, deglycerolized and resuspended
in a dextrose-saline solution. Only indate units may be frozen. |
| Indications:: The provision of blood for patients with antibodies
requiring rare units. The use of Frozen Deglycerolized Red Blood Cells to
prevent febrile transfusion reactions has been supplanted by the use of
Leukocyte Reduced Red Blood Cells. |
Plasma Components
PLASMA: SDPL, SDPL1, SDPL2, SDPL3, SDPL4 (6/25/07)
| Crossmatch: |
Not required, a blood sample may be required to determine
patient ABO and Rh type |
| Approximate Volume: |
200-275 mL SDPL |
| Outdate: |
5 days after thawing |
| Storage Conditions: |
After thawing, 1-6°C in a monitored blood refrigerator;
Return to Blood Bank immediately if not needed |
| Minimum Preparation Time: |
45 minutes unless processing of a blood specimen is required. Thawed plasma is available in 22 minutes, Of available, prethawed plasma is available in 15 minutes. |
| Dose: |
10-15 mL/kg body weight |
Description: Each unit of Plasmacontains the equivalent plasma obtained
by centrifugation and separation from one unit of whole blood. Plasma has the same risk of disease transmission
as Red Blood Cells. Plasma contains ABO anitbodies. While the levels of Factors V and VIII in thawed Plasma decreases slightly over 5 days, this is not clinically significant. Normal levels of coagulation factors including fibrinogen (300-500 mg/unit) are present.
|
| Indications::Plasma is indicated for patients with
a documented deficiency of coagulation factor for which there is not specific concentrate available. Patients requiring coagulation
factor VIII are best treated with coagulation factor VIII concentrate (available
from the pharmacy) or cryoprecipitated antihemophilic globulin.
Plasma may be used for correction of coagulation factor
deficiencies, Warfarin® reversal and microangiopathic hemolytic anemia
such as thrombotic thrombocytopathic anemia.
Plasma is indicated for patients with coagulopathy due to massive transfusion and replacement of specific plasma proteins.
|
| Contraindications:Plasma is not indicated for prophylactic
use when the INR is < 1.5 and the APTT is <1.5 times the upper linit of normal. |
Infusion Instructions: Rate: 10 mL/minute
Plasma components must be administered through a standard blood
infusion
The usual volume of Plasma is between 175 and 250 mL
Previously frozen plasma does not contain red blood cells. Plasma
from Rh positive donors may be given to patients who are Rh negative. |
Platelets
PLATELETS LEUKOCYTE REDUCED (PPLR), Prepooled Platelets, Leukocyte Reduced (PPLRP and PLP5)
Revised 10/9/07, 7/28/2008
| Crossmatch: |
Not required; a blood sample may be required |
| Approximate Volume: |
45-60 mL/unit; usually dispensed as a pool of 5 units
for a total volume of -225 to325 mL |
| Outdate: |
Single units or Prepooled-5d outdate five days after the date of collection
4 hours after pooling on-site.
Return component to Blood Bank immediately if component is no longer required |
| Storage Conditions: |
20-24°C (room temperature), with constant, gentle agitation. DO NOT REFRIGERATE. Do not store on patient units or in the operating room. |
| Minimum Preparation Time: |
10 minutes if prepooled, 20 minutes if pooled; 2 hours if volume reduced or washed |
| Dose Adult: 5 units |
| Pediatrics: 10-15 mL/kg body weight |
| Description: A minimum of 5.5 x 10 10th platelets harvested from
one unit of fresh whole blood in approximately 50 mL of donor plasma. Pooled platelets
usually represent a pool of five platelet units and contain 3.0 to 5.0 x
10 11th platelets in approximately 300 mL of plasma .The product is leukocyte-reduced
at the time of preparation by the blood supplier. This results in the infusion
of less than 8.3 x 105 white blood cells per component. Prepooled platelets are prepared in a standard dose
of 5 units per pool and are tested for bacterial contamination by a culture method. Individual whole blood platelets are tested for bacterial contamination on site by the pH method.
Platelet Counts: A 10 minute or 1 hour and a 24-hour post-transfusion
platelet count is recommended to assess patient response. |
| Indications:: Treatment of thrombocytopenia or defects of platelet
function. Requests must be substantiated by appropriate coagulation tests
and clinical data. Prophylactic use of this component for a thrombocytopenic
patient who is not bleeding is not indicated if the platelet count exceeds
10 x 10 9th/L. Patients undergoing major operative procedures generally should
have platelet counts above 70 x 10 9th/L for effective hemostasis. Each unit
of random donor platelets will raise the platelet count of an adult approximately
5-10 x 10 9th/L under optimal conditions, although clinical response to platelet
transfusions is diminished by fever, hypersplenism, infection, DIC, some
drugs and preformed antibodies to platelet antigens. Rarely indicated if
the platelet count is >100,000 unless there is platelet dysfunction.
Persistent failure to respond to the product may indicate a refractory
state. |
| Contraindications:: Transfusion of platelets to patients with
thrombotic thrombocytopenic purpura (TTP) or heparin-induced thrombocytopenia
is absolutely contraindicated, except in cases of life-threatening hemorrhage,
because fatal intravascular coagulation may occur. Transfusion of platelets
in idiopathic thrombocytopenic purpura (ITP), posttransfusion purpura, and
highly alloimmunized patients is ineffective because of their shortened
intravascular survival time, although they may be used at the time of splenectomy
or to treat active bleeding. |
| Availability: Requests for platelet pooled components should be made only if the component is to be transfused
immediately. To ensure maximum benefit and avoid unnecessary component loss,
Pooled Platelets should be transfused as soon as available. Platelets
must not be refrigerated. |
| Compatibility: ABO and Rh compatible platelets will be selected
and released for transfusion. If this is not feasible because of limited
inventory and/or emergent need for the component, ABO and/or Rh incompatible
platelets may be issued. |
| Rh Incompatibility:It may be advisable to administer Rho
(D) immune globulin to selected Rh-negative patients who receive platelets
from Rh- positive donors, since sensitization to red cell antigens may occur
from the few red cells present in platelets. |
PLATELETS, PHERESIS (Single Donor Platelets)
| Crossmatch: |
May be required. See crossmatched platelets. |
| Appriximate Volume: |
200-350 mL |
| Outdate: |
24 hours or 5 days depending on collection system |
| Storage Conditions: |
20-24°C (room temperature) with constant, gentle agitation. DO NOT REFRIGERATE |
| Minimum Preparation Time: |
24-48 hours after initial order, Pathology review required |
| Dose Adult: |
1unit |
| Description: Each unit of this component is obtained by automated
apheresis from one donor and contains a minimum of 3 x 10 11th/L platelets
(the equivalent of the number platelets contained in 5units of random donor
platelets) plus 200-350 mL of plasma with acid citrate dextrose (ACD) as
the anticoagulant. Leukocyte reduced Single Donor Platelets contain less
than 5 x 10 6th residual leukocytes. |
| Indications:: For aplastic anemia and clinical refractoriness.
Most surgical patients do not require platelet transfusion on a long-term
basis and can be transfused successfully perioperatively with random donor
platelets. |
| HLA-Matched Platelets: HLA-matched Single Donor Pheresis Platelets
are available through the Southeastern Michigan Red Cross Blood Center.
The patient's HLA type must be determined prior to or concurrent with the
initial order. The diagnosis of this refractory state is based on both clinical
considerations and the lack of the anticipated increase in the initial platelet
count 10 minutes or l hour and 24 hours after transfusion with random platelets. |
| Ordering Procedure: Requests for HLA platelets require a Pathology
consult and approval. |
CROSSMATCHED PLATELETS, PHERESIS
| Crossmatch: |
Performed at the Southeastern Michigan Red Cross. |
| Approximate Volume: |
200-350 mL |
| Outdate: |
24 hours or 5 days depending on collection system |
| Storage Conditions: |
20-24°C (room temperature) with constant, gentle agitation. DO NOT REFRIGERATE |
| Availability: |
24-48 hours after initial order |
| Description: Each unit of this component is obtained by automated
apheresis from one donor and contains a minimum of 3 x 10 11th/L platelets
(the equivalent of the number platelets contained in 5units of random donor
platelets) plus 200-350 mL of plasma with acid citrate dextrose (ACD) as
the anticoagulant. Leukocyte reduced crossmatched platelets contain less
than 5 x 10 6th residual leukocytes. Crossmatched platelets are selected by
a solid phase technique that tests the patient's serum against donor platelets.
Only platelets considered non-reactive are issued as crossmatched platelets. |
| Indications:: For patients refractory to platelet transfusions.
The diagnosis of this refractory state is based on both clinical considerations
and the lack of the anticipated increase in the platelet count 10 minutes
or l hour and 24 hours after transfusion with random platelets. |
| Ordering Procedure: Requests for crossmatched platelets require
a Pathology consult and approval. |
GRANULOCYTES, PHERESIS (GRAN)
| Crossmatch: |
Required |
| Approximate Volume: |
250-350 mL |
| Outdate: |
24 hours |
| Storage Conditions: |
20-24°C (room temperature) DO NOT REFRIGERATE |
| Minimum Preparation Time: |
24-48 hours |
| Dose: 1 unit per day until afebrile or WBC is >0.9 x109 |
| Description: Each unit contains approximately 1 x 10 10th granulocytes
obtained from a single donor by automated apheresis. This component also
contains 20-50 mL of red cells and may contain 2-3x10 11th platelets. |
| Indications:: Selected infected leukopenic patients with a
granulocyte count of less than 0.5 x 109/L who have not responded to more
than 48 hours of appropriate antibiotic therapy. Consult the Blood Bank
before ordering granulocytes. |
| Contraindications:HLA alloimmunization, transfusion reactions
to granulocytes. In some patients, granulocytes need to be collected from
CMV seronegative or HLA matched donors. Granulocyte transfusions should
be discontinued when the patient becomes afebrile, at the onset of transfusion
reactions, when the granulocyte count exceeds 1.0 x 10 9th/L or in the absence
of a clinical response after 14 days. Except in unusual circumstances, granulocyte
transfusions are not indicated when there is no expectation that the patient's
bone marrow will recover sufficiently to produce an adequate number of endogenous
granulocytes to sustain life. |
| Ordering Procedure: Requests granulocytes require a Pathology
consult and approval. Granulocyte transfusions must be ABO compatible with
the recipient. |
| Availability: This component will not be available for transfusion
until late evening or after midnight, yet should be transfused as soon as
available to ensure maximum benefit. |
| Infusion rate:Over 3-4 hours |
Administration Instructions:
Do not administer through a leukocyte- reduction or microaggregate blood
filter. Administer through a Standard blood filter (Abbott No. 1871 or
equivalent filter).
Granulocytes MUST NOT be transfused within 4-6 hours of IV amphotercin
or flucanazole administration.
Premedication with an antipyretic (acetaminophen is recommended) to avoid
the need to discontinue transfusion due to a severe febrile reaction.
Infuse SLOWLY over 4 hours. The rate of infusion is ultimately dictated
by the recipient's ability to tolerate the component volume and by adverse
reactions
Monitor the patient closely for moderate to severe symptoms such as urticaria,
hives, wheezing, dyspnea, severe headache, cyanosis, hypotension, agitation
and tachycardia.
If such symptoms develop, stop the transfusion, keep the IV line open
and notify the patient's physician and the Blood Bank physician on-call
for further instructions.
Document vital signs every 15 minutes during the entire procedure, every
30 minutes for four hours after the transfusion and then every four hours
for 24 hours |
CRYOPRECIPITATED ANTIHEMOPHILIC GLOBULIN (CRYO) (CRYOT) (CRYOP) (PTCRY)
(PTCR5)
Revised 3/22/07, 12/27/07
| Crossmatch: |
Not required, a blood sample may be required |
| Approximate Volume: |
5-10 mL per bag; may be dispensed as single units for neonatal patients and children or as pools for adults. As of January 2008, the prepooled dose is 5 per bag. For adults, two pools of 5 (PTCR5) are dispensed for the standard adult dose of 10 unit. . PTCRY (prepool of 10) has been discontinued by the blood supplier. |
| Outdate: |
For Coagulation factor VIII: 6 hours after thawing;
P pooled CRYO: 4 hours after pooling |
| Storage Conditions: |
20-24°C Do not store, transfuse immediately; DO NOT REFRIGERATE |
| Minimum Preparation Time: |
45 minutes for thawing and pooling |
| Dose: Fibrinogen replacement: adult dose 10 pooled units |
| Pediatrics: 5 mL/kg body weight |
| Description: CRYO is Cryoprecipitated protein derived from
the fresh plasma separated from a unit of whole blood. Each individual unit (bag) has approximately
100 units of Factor VIII activity, as well as 150-250 mg of fibrinogen,
suspended in 5-23 mL of plasma. A pool of 5 units is expected to raise
the fibrinogen level 25 to 50 mg/dL. |
| Indications:: Treatment of patients with Von Willebrand's
disease and the treatment of Factor XIII deficiency. Factor VIII concentrate,
available from the Pharmacy, is the product of choice for most hemophiliacs. |
| CRYO serves as a therapeutic source of fibrinogen. It may
be indicated when the fibrinogen is less than 100 mg/dL. It may also be
of value for surgical patients with a hemorrhagic diathesis due to uremia.
Consultation with the Blood Bank Medical Staff is required in these instances.
CRYO may also be used to prepare "surgical fibrin glue" for topical
hemostasis. |
| Pooling: Prepooled CRYO (PTCR5) is a standard dose of 5 units of CRYO as of January of 2008. If prepooled doses are not available CRYO is thawed
and pooled by Blood Bank personnel before issue for the convenience of nursing
staff and to ensure nearly complete transfer of the component to the patient.
CRYO components must be transfused as soon as possible after thawing to ensure maximum
patient benefit. |
Infusion Instructions:
CRYO from Rh positive donors may be given to patients who are Rh negative.
Infusion Rate 10 mL per minute.
Use either a standard blood administration set or a special blood component
administration set.
Do not use a leukocyte-reduction filter.
DO NOT REFRIGERATE CRYO as this causes reprecipitation and loss of Factor
VIII activity.
At the completion of transfusion, approximately 20-30 mL of isotonic saline
should be fed into the cryoprecipitate bag to rinse product adherent to
the walls of the bag. CRYO does not contain red blood cells.
Clinical response to the component can be measured with post-transfusion
coagulation studies.
|
PARTIAL UNITS
RED BLOOD CELLS, ALIQUOTS (RBC Divided, RBC Half)
| Crossmatch: |
Required for patients older than 4 months of age |
| Approximate Volume: |
1/2 units: 100-150 mL/unit;
syringes: 10 - 50 mL |
| Outdate: |
35 days (CPDA-1 anticoagulant)
4 hrs if dispensed in a syringe |
| Hematocrit: |
55% AS-1 or
70-80%, CPDA-1 |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
45 minutes |
| Description: Red Blood Cells prepared from a unit of whole
blood that is further divided into smaller volumes (aliquots). The hematocrit
of each individual unit ranges from 55 to 80% depending on the anticoagulant. |
Availability: Orders for partial units of Red Blood Cells
should specify the volume required for transfusion. When components are
packaged in syringes, unless otherwise requested, an additional 10 mL
of component will be added routinely to the syringe to allow for transfusion
tubing "dead space". The maximum volume to be contained in a
syringe is 50 mL. |
| Only group O blood is routinely available in syringes. A limited
number of prestorage leukocyte-reduced, sickle cell negative units are available
for newborn infants. Partial units may also be ordered for patients with
congestive heart failure when transfusion of a whole unit would be problematic. |
PLASMA, ALIQUOTS (FFPT1-3, FFPHA-D, SDP1-2, SDPA)
| Crossmatch: |
Not required, a blood sample may be required |
| Approximate Volume: |
variable; 50-100 mL in bags;
50 mL maximum in syringes |
| Outdate: |
4 hours after thawing;
4 hrs after dispensing into a syringe |
| Storage Conditions: |
After thawing, 1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
15-30 minutes for thawing and unit preparation |
| Description: Many partial units of Plasma are prepared from
group AB donors lacking anti-A and anti-B. The plasma is frozen within eight
hours of collection to preserve coagulation factors V and VIII (see Fresh
Frozen Plasma). |
Indications:: When prepared from AB donors this component
is suitable for transfusion to all neonates regardless of ABO type whenever
a small volume of plasma is required. It can be made available for other
pediatric patients by special request. |
RESUSPENDED LEUKOCYTE REDUCED WHOLE BLOOD
| Crossmatch: |
Required in some circumstances |
| Approximate Volume: |
350-500 mL |
| Outdate: |
24 hours after resuspension |
| Hematocrit: |
42 or 50% |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
1 hour |
| Description: Red Blood Cells from which the supernatant storage
solution has been removed and resuspended in Fresh Frozen Plasma Liquid
to approximately a 50% hematocrit. |
Indication: Exchange transfusion of a neonate. Resuspended
whole blood will not be prepared for other purposes unless approved by
the Blood Bank Medical Staff.
|
Rho(D) IMMUNE GLOBULIN (RHIG, WRHO)
| Dose: 300 micrograms anti-D |
| Storage Conditions: |
2-6°C |
| Description: A concentrated solution of gamma globulin
with a high level of anti-D activity. Both an intramuscular and intravenous
preparations are available. Both preparations are latex and thimerisol free. |
Indication: Prevention of alloimmunization of Rh-negative
women due to fetal maternal hemorrhage of Rh positive fetal cells, to
prevent sensitization of an Rh negative patient who received Rh positive
platelets,or to prevent sensitization due to the inadvertent administration of
a small volume of Rh positive Red Blood Cells. A sterilization procedure
immediately postpartum is not a contraindication to the administration
of the product, if it is otherwise clinically indicated.Indications for RHIG include abortion, antepartum fetomaternal hemorrhage,
amniocentesis, genetic amniocentesis, chorionic villus sampling (CVS),
percutaneous umbilical blood sampling (PUBS), at approximately 26-28 weeks
gestation and after delivery. The product circular should be consulted
for additional indications. The component is administered intramuscularly
within 72 hours of the potentially sensitizing event. It is generally
appropriate to administer the product even if this 72-hour period has
elapsed.It is necessary, on occasion, to administer platelets from Rh-positive
donors to Rh-negative patients. Although the platelets themselves do not
carry antigens of the Rh system, the component inevitably contains small
amounts of donor red cells that may sensitize of the recipient to the
D antigen. In some patients, particularly those who are young and non-immunosuppressed,
it may be advisable to administer RHIG when such a situation occurs. Consultation
with Blood Bank Medical Staff should be considered.
Intravenous WRHO is indicated for the treatment of ITP in Rh positive
adults and children. The product circular should be used for dosage and
administration guidelines. |
Specimen Requirements: Cord Blood Samples: When available, a cord blood sample from the fetus
or infant will be tested for the presence of the D antigen.
Maternal Samples: All pregnant women should have their Rh type determined
at the University of Michigan Hospitals Blood Bank. A blood specimen is
required for all Rh-negative women prior to the issuance of RHIG. A maternal
specimen collected one hour post procedure should be obtained for spontaneous
or therapeutic abortions after the 20th week of pregnancy, after hypertonic
solution pregnancy termination, or following delivery, in order to recognize
the rare patient with a massive fetomaternal hemorrhage. Antepartum blood
samples are satisfactory for spontaneous and therapeutic abortions before
the 20th week of pregnancy. |
| Determination of Dose: The Blood Bank routinely performs
a screening test for massive fetal-maternal hemorrhage postpartum to determine
if additional testing is required to establish the appropriate dose of RHIG.
On request, this screening test will be performed on specimens from antepartum
patients. |
VariZIG (TM) Varicella
Zoster IgG
| Crossmatch: |
Not required; no patient sample required |
| Approximate Volume: |
125 international units/vial |
| Dose: 1 vial per 10 kg body weight to a maximum of
5 vials |
| Administration: administered intramuscularly within
72 hours of exposure |
Indication: Indicated for immunosuppressed patients
with a recent exposure to chicken pox.
This product is available only to patients
who particiapte in research study. It is not stocked and must
be ordered and shipped as needed. Release, consent and study forms
are required. Refer to Pharmacy Web page http://ummcpharmweb/di/DispensingProcedures/VariZIGDispensingProcedures.pdf for information on ordering.
|
AUTOLOGOUS COMPONENTS
| Crossmatch: |
Required for RBC components |
| Outdate: |
21 days to 42 days depending on the anticoagulant |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Minimum Preparation Time: |
Donations must be scheduled and units collected at least four days in
advance of proposed date of use. At least two week prior donation is recommended. |
| Description: Whole Blood or Red Blood Cells collected
from a patient/donor and stored for future use. |
| Requirements: Patient with a hemoglobin of at least
11 gm/dL (33% hematocrit) who is not bacteremic and who has an anticipated
blood need greater than 2 units during the dating period of the component
may donate. Patients should be given oral iron therapy. |
Indication: Patient request when there is some reason
to believe that there is a risk of blood transfusion for an up coming
operative procedure. In rare circumstances autologous blood may be collected
when it is difficult to find compatible blood due to antibodies directed
at red cell antigens. |
Collection Sites:
The University of Michigan Hospitals does not collect Autologous Whole Blood.
Donations may be made at any licensed or registered blood donor center in
Michigan, at any hospital in Michigan that routinely collects donor units,
or any U.S. hospital or donor center outside the state of Michigan that
is licensed by the Office of Biologics, Food and Drug Administration (allows
for the interstate shipment of blood). In order to coordinate shipping,
payment and tracking of units, the University of Michigan Hospitals Blood
Bank must be notified in advance that the patient is donating autologous
blood.
There are additional fees assessed by the agency collecting the
blood. These fees are charged regardless if the unit is transfused and
are not generally reimbursed by healthcare insurance programs.
In rare circumstances autologous blood may be frozen and stored off site
for up to three months. There are additional fees for freezing and deglycerolization. |
DIRECTED DONOR COMPONENTS
Units shipped from donor centers
may not be prestorage leukocyte-reduced. Such units will be issued with
a leukocyte-reduction filter to be used for transfusion of the components.
5/1/06
| Crossmatch: |
Required for RBC components |
| Outdate: |
21 days to 42 days depending on the anticoagulant |
| Storage Conditions: |
1-6°C in a monitored blood refrigerator |
| Availability |
Four working days from the time of donation must be allowed for processing
and shipping of units |
Indications:
There are few, if any, indications for the use of directed donor blood
components. Directed donor units are collected for patients with an anticipated
blood need, at the request of the patient (parent or guardian) and the
patient's physician. Directed Donor units must be fully processed, and
only donor units meeting American Association of Blood Banks and Office
of Biologics, Food and Drug Administration requirements may be used for
transfusion.Due to the special handling, an additional service fee is charged
per unit donated. These additional are not covered under most health insurance
plans. In addition, there are additional fees for directed donor units
as they must be irradiated to prevent posttransfusion graft-versus-host
disease.
Donations for patients being treated at the University of Michigan Hospitals
may be made at any licensed or registered blood donor center in Michigan,
at any hospital in Michigan that routinely collects directed donor units,
or any U.S. hospital or donor center outside the state of Michigan that
is licensed by the Office of Biologics, Food and Drug Administration (allows
for the interstate shipment of blood). In order to coordinate tracking,
payment and shipping of units donated at other centers, the University
of Michigan Hospitals Blood Bank must be notified in advance that the
patient has selected his/her own donors. |
IRRADIATED BLOOD PRODUCTS
| Outdate: |
