Healthcare providers can also take a swab of an area that has symptoms and run DNA tests known as Nucleic Acid Amplification Testing (NAAT). There is less chance of a false negative result with NAATs. Blood tests do not actually detect the virus; instead, they look for antibodies (the body’s immune response) in the blood. For this reason, we do not recommend using blood tests as a way to determine how long a person has had herpes. Herpes blood tests (also called HSV-2 type-specific serologic tests) can be very useful for diagnosing type 2 genital herpes infection in certain situations; 1) when someone has genital symptoms that might be related to herpes, and 2) when someone has a sex partner with symptomatic genital herpes. Genital herpes infections can cause intermittent symptoms that may be uncomfortable, but infection does not usually result in serious complications in healthy adults.

IgM antibodies are produced very soon after an infection. 8) The CDC does NOT recommend routine blood testing for herpes.
It’s not always clear what to do with the test results. If you test positive, taking an anti-viral drug may help you avoid outbreaks and reduce viral shedding, which means youre less likely to infect sex partners. A negative test result indicates that the herpes simplex virus was not isolated but does not definitely rule out the presence of virus. Results will usually come back within 7 to 10 days, but some clinics may take longer. Most blood tests are accurate 12 to 16 weeks after possible exposure to HSV. A positive herpes test does not tell you how long you have had the virus or where it will show up on the body.
It can take any time from two to seven days to get viral culture results back from the laboratory, which may mean several visits to your Doctor before a diagnosis is confirmed. Blood tests do not require swabbing a lesion, so they can be done long after symptoms have faded. So, if you have an ulcer or lesion, always insist on lab testing in addition to an exam. However, it can take 3-4 months after a possible exposure to produce enough antibodies, therefore if you can identify the exposure, you should wait that long to have the test. So I did what I do best in those types of situations. I texted my friend Katie and whined about it. A week later, I was lying in bed when my lab results popped up via email.

Blood tests do not actually detect the virus; instead, they look for antibodies (the body’s immune response) in the blood. The challenge here is that the time it takes for IgG antibodies to reach detectable levels after initial infection can vary from person to person. So even with the accurate tests, a person could receive a false negative if the test is taken too soon after contracting the virus. Does this sound like herpes? Learn what to expect during the test and what the results may mean.

Interpretation of test results: positive or negative?. It takes time for immune system to develop antibodies after catching the first infection.
