Test Overview
Test Methodology
  • Macroscopic:Arkray Uriflet S 9HA Strip (automated) or Chemstrip 10 ( manual).
  • Microscopic: Arkray Aution Hybrid flow cytometer (automated) or manual microscopy .
Test Usage

Screening test for abnormalities of urine or renal function. To isolate and identify organisms causing urinary tract infection.

Reference Range *

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. . Microscopic examination in the absence of these findings requires approval. Call the laboratory at 936-6866 between 8am and 5pm Monday through Friday for pathologist approval. All other times, page the Hematopathology/Flow Trainee on call. 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.
