Specimen Requirements


Specimen

First-void urine in Aptima® urine transport


Volume

2 mL aliquot of a 20-to-30 mL urine collection


Container

Aptima® Urine


Collection

The patient should not have urinated for at least one hour prior to specimen collection. Direct patient to provide a first-catch urine (approximately 20 mL to 30 mL of the initial urine stream) into a urine collection container free of any preservatives. Collection of larger volumes of urine may result in specimen dilution that may reduce test sensitivity; lesser volumes may not adequately rinse organisms into the specimen. Female patients should not cleanse the labial area prior to providing the specimen. Add urine to the Aptima® urine collection device. The final volume must be between the two black lines on the device (about 2 mL).
