Reference Range:
*Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Reference ranges are available in the iStat CG4+ Blood Gas and Lactate test procedure located on the POC website: https://www.pathology.med.umich.edu/point-of-care
Test Usage:
Performed at authorized locations by point of care operators. pH, PO2, PCO2 measurements are used in the diagnosis monitoring, and treatment of respiratory disturbances and metabolic and respiratory-based acid-base disturbances. Lactate measurements are used in (1) the diagnosis and treatment of lactic acidosis in conjunction with measurement of blood acid/base status, (2) monitoring tissue hypoxia and strenuous physical exertion, and (3) diagnosis of hyperlactatemia.
Test Limitations:
•Prolonged tourniquet application and forearm exercise may decrease pH due to localized production of lactic acid. •Exposure of sample to air will cause an increase in pH , a decrease in pCO2 and increase in pO2. •Results may be affected in the following situations: hemolysis, traumatic draw, pumping fist during draw, extended delay between drawing and testing thee specimen.
Test Methodology:
Abbott I-Stat - ion selective potentiometry (pH, PCO2), amperometrically (pO2, lactate), calculation (HCO3)
