Chlamydia/Gonococcus/Mycoplasma genitalium, NAA, Urine
Use
Detect Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium
Special Instructions
Patients should refrain from urinating for at least one hour prior to sample collection to ensure accuracy. The test uses a first-catch urine specimen collected in a specific transport medium (Aptima® urine transport).
Limitations
The test may have reduced sensitivity if the urine volume exceeds the specified amount or if the specimen is not properly rinsed into the collection container. Specimens with a fixative or those collected in an improper transport medium may be rejected. False negatives may occur due to inadequate sample collection or transport error.

Collection Instructions
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® Combo 2 urine collection device. The final volume must be between the two black lines on the device (about 2 mL).
Patient Preparation
The patient should not have urinated for at least one hour prior to specimen collection.
Storage Instructions
Maintain specimen at room temperature or refrigerate (2°C to 30°C).
Causes for Rejection
Specimen with incorrect patient identification; unlabeled specimen; inappropriate specimen transport conditions; specimens received after prolonged delay (usually >72 hours); specimen leaked in transit; specimen in expired transport or incorrect transport device; specimens with inappropriate source for test requested; specimen with fixative or additives; Aptima® urine transport >30 days from collection; Aptima® urine transport with incorrect specimen volume; specimen in ProbeTec™ UPT transport; ProbeTec™ Q-swabs; urine in sterile container
