Detail Description

Clinical Significance

Urinalysis, Complete, with Reflex to Culture - Dipstick urinalysis is important in accessing the chemical constituents in the urine and the relationship to various disease states. Microscopic examination helps to detect the presence of abnormal urine cells and formed elements. Culture may identify the organism(s) causing infection.

Preferred Specimen(s)
Submit two separate specimens:
1) 10 mL urine submitted in urinalysis transport tube (yellow-top, blue fill line, preservative tube)
2) 4 mL (fill to minimum line printed on tube; unpreserved for cultures) urine in urine culture tube (gray-top)

Alternative Specimen(s)
Refrigerated unpreserved pediatric sample • Yellow/red swirl-topped conical transport tube with preservative

Minimum Volume
Preserved (yellow-top, blue fill line): 1 mL
Urine in urine culture tube (gray-top): Must be filled to minimum line printed on tube
Unpreserved (culture): 0.5 mL

Collection Instructions
Encourage clean catch mid-stream samples to minimize contamination and improve accuracy. If sample is submitted unpreserved, please indicate that specimen is from pediatric patient (patient is less than or equal to 12 years of age). Label the sample appropriately. Unpreserved urine will be accepted from pediatric patients only.
