Herpes Simplex Virus Type 2 DNA (Genomic) by Nucleic Acid Probe
This test detects the presence of genetic material from herpes simplex virus type 2 (HSV-2), which causes genital herpes. It helps confirm an infection that may not cause obvious symptoms.
["This test can help diagnose genital herpes caused by HSV-2, even if you don’t have active sores or symptoms."]

Why Is This Test Done?
Your healthcare provider may recommend this test if you have symptoms like sores, itching, or unusual discharge in the genital area, or if you have recurring outbreaks. It can also be used to confirm an infection in people with no symptoms or mild symptoms. This test is often part of a broader evaluation for sexually transmitted infections (STIs).
How Is the Test Performed?
A small sample of fluid (such as from a sore or swab from the genital area) is collected and sent to a lab. The lab uses a specialized probe to detect the virus’s genetic material in the sample. This process is highly sensitive and can identify the infection even when symptoms are absent.
What Does a Positive Result Mean?
A positive result means the test found genetic material from HSV-2, indicating an active or past infection. This does not always mean you are currently experiencing symptoms, and it does not determine how contagious you are at the time of testing. Treatment can help manage symptoms and reduce transmission.
What Does a Negative Result Mean?
A negative result means the test did not detect HSV-2 genetic material in the sample. However, it is possible the infection was present at a very low level or that the sample was not collected correctly. Repeat testing may be recommended if symptoms persist or recur.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is crucial for diagnosing genital herpes caused by HSV-2, which can lead to complications if untreated, such as recurrent infections, chronic pain, or increased risk of HIV transmission. Early diagnosis allows for appropriate treatment and counseling on infection control measures. It also helps in managing long-term health risks, such as increased likelihood of cervical cancer in women.
