The vesicles break and leave painful ulcers that may take two to four weeks to heal after the initial herpes infection. Experiencing these symptoms is referred to as having a first herpes “outbreak” or episode.

Herpes tests are done to find the herpes simplex virus (HSV). Results for a rapid viral culture may take 2 to 3 days, while results for a standard culture can take up to 14 days. Antigen detection test results are ready in a day. Polymerase chain reaction (PCR) test results are ready in 1 to 3 days.

The time required for the development of IgG antibodies following HSV infection varies from 21 to over 42 days with most individuals having detectable IgG 21–28 days after exposure to the infection and probably lasting for life.7–,9 IgM antibodies are usually detectable 9–10 days after exposure and last 7–14 days, ...

False positive HSV-2 results can happen, especially in people who are at low risk for a herpes infection. Also, we do not know if people who test positive for herpes will change their sexual behavior as a result of a positive test.
