If you do not have obvious symptoms, a blood test can help determine whether you have an infection. The gold standard for herpes diagnosis is a viral culture test or nucleic acid amplification test NAT of a sample of skin, crust, or fluid from a lesion.
This is usually obtained with a gentle swab of the area. A viral culture is a test that allows the virus to grow in a laboratory setting. The NAT tests for the genetic material of the virus in the sample. These tests should only come back positive if you have the virus present in the lesion. In general, the results of the test are reliable if you have active lesions.
It is possible to screen for asymptomatic herpes infections using a blood test. Herpes blood tests can detect antibodies to the herpes virus. You form these proteins when you need to fight an infection. Generally, it takes about two weeks for your body to produce enough antibodies against herpes to be detectable.

However, more complicated neonatal herpes infections, such as encephalitis infection of the brain , require specific tests such as a spinal tap.
