Why This Test Is Done
Your healthcare provider may order this test if you have symptoms like sores, itching, or unusual discharge in the genital region, or if you have a history of herpes. It can also be used to confirm a diagnosis in cases where symptoms are unclear or to check for recurrence.
The test uses a molecular probe to detect genetic material (DNA) from HSV in a sample collected from your genital area. This method is highly sensitive and can identify the virus even when symptoms are not present.
The sample is analyzed in a lab to check for HSV DNA. Results are typically reported as positive (indicating HSV DNA is present) or negative (no detectable HSV DNA).
What to Expect Before the Test
No special preparation is needed. You may be asked to clean the genital area gently with mild soap and water before the sample is collected. The provider will guide you on how to collect the sample safely.
A healthcare provider will collect a sample from the affected genital area using a sterile swab. This is usually a quick and painless procedure, similar to a Pap smear.
The sample is sent to a lab for analysis. Results are usually available within a few days, depending on lab processing times.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is crucial for diagnosing genital herpes caused by HSV. Detecting HSV DNA helps confirm the diagnosis, especially in cases where symptoms are mild or unclear. Early diagnosis allows for appropriate treatment, management of outbreaks, and guidance on preventing spread to others.
