| Comments: |
Urinalysis with Reflex Microscopic & Culture if indicated. Automated analysis for urine chemical (dipstick) analysis, and microscopic exam and culture if abnormalities of screening parameters are detected. Criteria for urine microscopic: turbidity, nitrite, leukocyte esterase, blood or protein. Criteria for urine culture: WBC >5/HPF and/or leukocyte esterase positive and/or nitrite positive. NOTE: Some organisms do not elicit a typical UTI presentation (i.e., elevated WBC in the urine), and so may be missed by this reflex testing. If there is a strong initial clinical suspicion of UTI, or if symptoms persist despite normal screening test results, urine culture should be ordered rather than a reflex culture if indicated. |
| Rejection Criteria: |
Frozen specimen; fecal contamination; insufficient specimen; specimen submitted with needle attached; unpreserved specimen held more than 24 hours.
