Edit Date:

Specimen Collection Details
Collection:
Clean catch/midstream, catheter, cystoscopic, or suprapubic urine in a sterile plastic container. Do not submit syringes with needles attached.
Handling:
Keep refrigerated. Send to the laboratory within 24 hours. If delayed, submit the specimen in a urinalysis preservative tube, available from Client Services. These special tubes are not designed for use with urine for urine culture.
Stability:
24 hours refrigerated or 72 hours preservative tube.
Standard Volume:
10 mL urine.
Minimum Volume:
6 mL urine (smaller volumes reported with disclaimer).
Transport:
Refrigerated, or in urinalysis preservative tube.
Comments:
Includes urinalysis with microscopic exam. Culture added if WBC >5 and/or Leukocyte Esterase positive and/or Nitrite positive. NOTE: In-house studies show that these screening parameters result in detection of most positive urine cultures (93% sensitivity). 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 longer than 24 hours.
