Why This Test Might Be Ordered

Your healthcare provider may order this test if you have symptoms like sores, fever, or other signs of HSV-1 infection, or if you have a history of recurrent infections. It may also be used to evaluate individuals with suspected primary infection or to confirm exposure in certain clinical scenarios.

What the Test Involves

A blood sample is taken from a vein in your arm. The sample is then analyzed in a lab to detect the genetic material of HSV-1 using a specialized probe technique. This process helps identify whether the virus is present in your bloodstream.

What to Expect Before the Test

No special preparation is typically needed for this test. You may be asked to fast before the blood draw if it is part of a larger panel, but this is not always the case. Always follow your healthcare provider’s instructions.

What to Expect During the Test

The blood draw is usually quick and painless. You may feel a slight pinch when the needle is inserted, but most people tolerate it well. You can usually return to your normal activities immediately after.

Frequently asked questions

How long does it take to get results from this test?
Results from this test are typically available within a few days to a week, depending on your lab’s processing schedule. Your healthcare provider will contact you once the results are ready.
What does a positive result mean?
A positive result indicates the presence of HSV-1 DNA in your blood, suggesting an active infection. This does not necessarily mean you have symptoms, and treatment may still be recommended to manage the virus.
Can this test be used to detect past infections?
This test specifically detects active HSV-1 infection by measuring viral DNA. While it can indicate recent exposure or active infection, it does not directly measure past infections like antibodies. Antibody tests may be used for that purpose.
