Chlamydia trachomatis, Neisseria gonorrhoeae, and Herpes Simplex Virus (HSV) Types 1 and 2, NAA

Clinical Use

Order Test

Use

Diagnosis of Chlamydia trachomatis and Neisseria gonorrhoeae infections; detect and type active HSV shedding.

Special Instructions

This test is not FDA cleared or approved. Specimens collected from children under 13 years or without the age of the patient may be tested and reported with a disclaimer. Ensure proper handling of specimens, especially for Aptima® swabs, to avoid contamination. Turnaround time can vary based on additional reflex tests that might be required.

Limitations

The test is intended as an aid in diagnosing HSV infections with active viral shedding and differentiating HSV-1 from HSV-2. Negative results do not exclude the possibility of past infections as they reflect the absence of active viral shedding at the time of testing. For HSV testing, results are not indicative of the previous infection status and are intended to identify current viral shedding only.
