Test Overview
Test Methodology

<ul><li>
Macroscopic:Arkray Uriflet S 9HA Strip (automated) or Chemstrip 10 ( manual).<li>
Microscopic: Arkray Aution Hybrid flow cytometer (automated) or manual microscopy
</ul>

Test Usage

Screening test for abnormalities of urine or renal function.

Reference Range *

Urinalysis Reference Ranges are available online at http://www.pathology.med.umich.edu/handbook/Tables/UA.pdf.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

Macroscopic analysis for blood using the automated Arkray Uriflet S 9HA Strip detects only free hemoglobin and not intact Red Blood Cells. Negative macroscopic blood results may be reported when intact Red Blood Cells are seen on microscopic exam.

Specimen Requirements
Collection Instructions

Collect random clean catch midstream urine specimen and send in sterile plastic urine container or transfer to Light Yellow top UA tube AND Vacutainer® Urine C&S Transport kit. Refrigerate and send specimens within 24 hours of collection; specimens may be stored at room temperature if received within 2 hours of collection.

Special Handling

Gray top tubes and Vacutainer® tubes with red and yellow swirl tops will be accepted for manual analysis only. They cannot be analyzed on the AU-4050 urinalysis system.

Rejection Criteria
<ul><li>
Specimens received in improper containers.
Specimens received at room temperature greater than 2 hours from time of collection.
Specimens received refrigerated greater than 24 hours from time of collection.
Unlabeled or mislabeled specimens.
Specimens in containers with preservatives.
Specimens in containers with disinfectant or detergents.
</ul>
See special handling for urines received in gray or red and yellow swirl top tubes.
Normal Volume
15 mL urine
Minimum Volume
0.5 mL urine
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.
