How the Test Works

The test involves collecting a sample from your genital area (such as a swab or fluid) and analyzing it for genetic material from chlamydia and gonorrhea bacteria. A probe detects these specific genetic sequences, confirming if the infection is present.

Sample Collection

A healthcare provider will collect a sample using a sterile swab or by collecting fluid from your genital area. This is usually done during a routine exam or a quick office visit. The sample is then sent to a lab for testing.

What to Expect Before the Test

No special preparation is needed for this test. You may have a light vaginal exam if the sample is taken from the cervix, but it won’t cause discomfort. If you’re pregnant, inform your healthcare provider before the test.

What to Expect During the Test

The test itself is quick and painless. You might feel mild discomfort during sample collection, but it shouldn’t last long. If you’re uncomfortable, let your provider know.

Clinical interpretation

Frequently asked questions

Why was I asked to take this test?
Your healthcare provider may recommend this test if you have symptoms of an STI, such as unusual discharge, pain during urination, or unusual bleeding. It’s also routinely recommended for sexually active individuals, especially those with multiple partners or recent exposure to these infections.
What does a positive result mean?
A positive result means the test detected genetic material from chlamydia or gonorrhea bacteria, indicating an active infection. This requires immediate medical treatment with antibiotics to clear the infection and prevent further complications.
How soon will I get my results?
Results are typically available within 24 to 48 hours. Your healthcare provider will discuss the results with you during a follow-up visit.
