Chlamydia/Gonococcus, NAA With Confirmation
Also known as: Chlamydia/Gonococcus, Aptima® TMA
Use
Detect Chlamydia trachomatis and Neisseria gonorrhoeae (Gonococcus)
Special Instructions
Submit one specimen per test requested. Specify the exact specimen source or origin (e.g., endocervical) on the test request form. It requires the Gen-Probe® Aptima® transport system for collection. Specimens should be collected and stored according to the instructions for each type of specimen to maintain integrity and accuracy of the test results. Patient preparation involves not urinating for at least one hour prior to specimen collection.
Limitations
Chlamydia/Gonococcus NAA cannot be conducted on specimens that are concurrently used for routine chemistry or urine culture as the chemical preservatives interfere with the test. The test requires a first-catch urine specimen, unlike routine tests which often employ a clean-catch method. Inappropriate transport conditions or contamination with mucus can lead to test rejection. Additionally, false negatives may occur if the organisms are below detectable limits or not collected properly.
