How the Test Works
A healthcare provider collects a sample from your genital area using a sterile swab. The swab is then analyzed in a lab to identify genetic material from specific STIs, including chlamydia, gonorrhea, and other pathogens. This method is highly sensitive and can detect infections even when symptoms are not present.
Sample Collection
The test uses a swab to gather cells and fluids from your genital area. This is typically done during a routine office visit or clinic visit. You may be asked to clean the area with mild soap and water beforehand to ensure the sample is representative.
What to Expect Before the Test
No special preparation is needed for this test. You may have a slight discomfort or mild burning sensation during the swab collection, but it usually lasts only a few seconds. If you experience pain or unusual bleeding afterward, contact your healthcare provider.
Common Infections Detected
This test can identify genetic material from common STIs such as chlamydia, gonorrhea, and sometimes human papillomavirus (HPV) and other bacteria or viruses depending on the specific probe used. Early detection is crucial for prompt treatment and prevention of complications.
