Herpes Simplex Virus Type 2 DNA Quantitative, Genital Specimen, Nucleic Acid Amplification Probe
This test detects the presence of genetic material from the herpes simplex virus type 2 (HSV-2), which can cause genital herpes. It helps determine if you have an active infection or have been exposed to the virus.
["This test can help diagnose genital herpes caused by HSV-2 and guide treatment decisions."]

Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms such as sores, blisters, or pain in the genital or anal area, unexplained genital sores, or if you have a history of genital herpes. It may also be used during pregnancy to check for active infection.
How the Test Works
The test uses a special probe to detect tiny amounts of HSV-2 DNA in a sample taken from genital areas (e.g., swab). Nucleic acid amplification techniques amplify these DNA fragments for precise detection, even in low levels.
Sample Collection
A healthcare provider will collect a sample using a sterile swab from affected genital areas. The swab is then sent to a lab for testing.
What to Expect After Testing
Results are typically available within a few days. If the test is positive, it confirms HSV-2 infection. If negative, it means the virus was not detected at the time of testing, but you may still carry the virus without symptoms.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates an active HSV-2 infection, which can be managed with antiviral medications to reduce symptoms and outbreaks. It also informs sexual partners about potential transmission risks. A negative result does not rule out past infection; symptoms may appear later or without testing.
