Container: Urine Specimen Preservative Tube (Cherry Red/Yellow Top or Stockwell Tube)
- Collect urine sample according to standard protocols.
- Transfer aliquot from a clean urine cup into a urine specimen tube using the vacutainer transfer device included with the tube.
- Gently invert tube 8-10 times.
- Label tube according to standard protocols.
Patient Preparation: Patient should be instructed to collect a “clean-catch, midstream” urine specimen.
Transport: Store urine at 2°C to 8°C after collection and ship the same day per packaging instructions provided shipping box.

Refrigerated (2-8°C): 72 hours
Frozen (-20°C): not acceptable
Causes for Rejection: Specimens other than urine sample in a preservative tube; improper labeling; samples not stored properly; samples older than stability limits; grossly bloody or mucoid samples.
Methodology: Colorimetric/Automated Microscopic
Turn Around Time: 1 to 3 days
Limitations: Unusually colored urine due to medication, azo dyes (Pyridium, Azo Gantrisin, and Azo Gantanol) or riboflavin may interfere with any of the urine tests below.

Clinical Significance: Dipstick urinalysis measures chemical constituents of urine. Microscopic examination helps to detect the presence of cells, bacteria, yeast and other formed elements.
