URINE: The patient should not have urinated for at least 1 hour before specimen collection. Direct patient to provide a first-catch urine (approximately 20-30 mL of the initial urine stream) into a leakproof urine collection cup free of any preservatives. Collection of larger volumes of urine may result in specimen dilution that may reduce test sensitivity. Female patients should not cleanse the labial area before providing the specimen. Thus, a urine sample collected from a female for Chlamydia/GC TMA cannot be collected at the same voiding event as that urine which would be intended for bacterial culture (the latter needs to be a clean catch). Minimum 2 mL of urine specimens must be transferred into the APTIMA® specimen transport tube within 24 hours of collection, and before being assayed. Collection Container: Tube in the APTIMA® Urine Specimen Collection Kit for Urine Specimens. The fluid (urine plus transport medium) level in the urine transport tube must fall within the clear pane on the tube label.
