Specimen Volume: 8 mL
Specimen Minimum Volume: 5 mL
Specimen Stability Information
Ambient:
Non-preservative tubes: 2 hours
Preservative tubes: 72 hours
NOTE: Preservative specimens are accepted but are not recommended.
Refrigerated: 8 hours
Rejected Due To
- Unlabeled specimens
- Ambient specimens >2 hours old

Testing Algorithm
If specimen clarity is reported as cloudy or turbid, blood is reported as positive, protein is reported as positive, nitrite is reported as positive and/or leukocyte esterase is reported as positive, then a Urine Microscopic (LAB348) will be performed at an additional charge.
If Urine Microscopic (LAB348) is performed and the WBC is >10/HPF then the Urine Culture (LAB239) will be performed at an additional charge.

Interpretation
Color: Yellow
Apearance: Clear
Glucose Urine: Negative
Ketones Urine: Negative
Specific Gravity Urine: 1.001-1.035
Blood Urine: Negative
pH Urine: 5.0, 5.5, 6.0, 6.5, 7.0
Protein Urine: Negative
Urobilinogen Urine: 0.2 E.U./dL, 1.0 E.U./dL
Nitrite Urine: Negative
Leukocyte Esterase: Negative
Cautions
Substances/conditions that cause abnormal urine color may affect the readability of reagent areas on urinalysis dipstick reagent strips and may cause false positive or false negative results.
Insufficient urine volume can produce erroneous results, including falsely decreased urine microscopic semiquantitative results for WBC, RBC, epithelial cells, casts, and bacteria.
