Herpes Simplex Virus Type 1 DNA Detection (Quantitative)

This test measures the levels of specific substances in your body, giving your healthcare provider valuable information about how well certain organs and body systems are working. If any values fall outside the expected range, it may point to a condition that needs further evaluation.

The test looks for the virus’s genetic material (DNA) in a sample of your bodily fluid, such as saliva or blood, using a highly sensitive molecular technique. This helps identify whether HSV-1 is currently active in your body.

Your provider may order this test if you have symptoms that could suggest a health problem, if you have a condition that requires regular monitoring over time, or as part of a routine checkup to screen for potential issues before they cause noticeable signs.

Your healthcare provider may order this test if you have symptoms like sores, pain, or flu-like symptoms that could be caused by HSV-1, or if you have recurrent infections that don’t seem to improve with usual treatments.

A trained healthcare professional will collect a small sample, most often by drawing blood from a vein in your arm using a sterile needle. The process usually takes just a few minutes, and you may feel a brief pinch. Afterward, a small bandage is placed over the site and you can return to your normal activities.

A small sample of saliva or sometimes blood may be collected. Saliva is often preferred for this test because it can detect the virus more easily and is less invasive.

Results are generally described as normal when your values fall within the expected range, or abnormal when they are higher or lower than expected. An abnormal result does not always mean you are ill, so your provider will review your numbers along with your symptoms and medical history and may recommend follow-up testing if needed.

A positive result means the test found HSV-1 DNA, suggesting an active infection. A negative result means the virus wasn’t detected in the sample at the time of testing, but this doesn’t always mean you’re completely free of the virus.
