10 mL urine - Urinalysis transport tube (yellow-top, blue fill line, preservative tube)

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

Minimum Volume
Preserved: 1 mL
Unpreserved (pediatric only): 1 mL

Transport Container
Yellow-top, blue fill line urinalysis transport tube

Transport Temperature
