Days Set Up:
Daily
Reference Range:
*Reference ranges may change over time. Please refer to the original patient report when evaluating results.
CULTURE: No significant organisms isolated. Urinalysis Reference Ranges are available online at http://www.pathology.med.umich.edu/handbook/Tables/UA.pdf.
Test Usage:
Screening test for abnormalities of urine or renal function. To isolate and identify organisms causing urinary tract infection.
Test Limitations:
Macroscopic analysis for blood using the automated CLINITEK Novus 10 Urinalysis Cassette detects only free hemoglobin and not intact Red Blood Cells. Negative macroscopic results may be reported when intact Red Blood Cells are seen on microscopic exam.
Test Methodology:
  • Macroscopic: CLINITEK Novus 10 Urinalysis Cassette (automated) or Chemstrip 10 ( manual).
  • Microscopic: Sysmex UF-5000 flow cytometer with UD-10 digital imaging (automated) or manual microscopy .
  • Culture.
Additional Information:
Microscopic exam will be performed at an additional charge only on specimens that are positive for one or more of the following analytes: leukocyte esterase, nitrite, blood, hemoglobin, glucose, ketones, or protein. Call the laboratory at 936-6866 to speak with a Medical Laboratory Scientist about adding microscopic exam to urinalysis. Aerobic urine culture will be performed at an additional charge if abnormal leukocyte esterase or nitrite is found on Macroscopic exam or if abnormal bacteria or yeast results are found on Microscopic exam. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
