PrEP Use Only: Chlamydia/Gonococcus, Urine or Urogenital Swab, NAA
Also known as: Pre-exposure prophylaxis screening for Ct/GC, Urine or Urogenital (Aptima®) Swab Source
Use
This test is for PrEP use only. Testing includes detection of Chlamydia trachomatis or Neisseria gonorrhoeae in urine or swab specimens.
Special Instructions
Not provided.
Limitations
The test has specific requirements for specimen collection that must be adhered to. It cannot be used in conjunction with routine chemistry or urine culture due to differences in collection techniques. Using a first-catch urine sample is critical to maintain test sensitivity, while clean catch midstream specimens are unsuitable for this testing. Furthermore, any deviation from the storage instructions or using improper transport containers can lead to specimen rejection.

Causes for Rejection
Specimens with incorrect patient identification, unlabeled specimens, improper transport conditions, leaked specimens, expired transport containers, inappropriate source for test, or improper specimen volume will be rejected. Certain swabs and containers are not compatible with this testing, including any non-Gen-Probe® swabs, wooden-shafted swabs, bacterial swabs, and specimens collected in inappropriate media.
