<2 weeks: It usually take1-2 weeks for a healthy immune system to produce IgM anti-bodies to a viral infection. There are 2 types of herpes simplex 1 and 2, so both tests are available. If a patient has IgG herpes antibodies then the patient has already been exposed 'some time ago.' hope that helps.

2-6 weeks: There are variations in individual immune response and it could take 2-6 weeks to detect antibodies in blood.
Have a healthy diet, exercise, drink plenty of water, have safe sex, and get HPV vaccine. Wish you good health!

What is the likelihood of a false negative herpes type specific blood test with background of lupus (sle)?

About 0% to 9%: Quest diagnostics' website states that their herpes type-specific IgG antibody test is 91-100% sensitive, so there are a few false negative results. A repeat test can be done 4-6 weeks later, if worried about a false negative. Lupus should not affect the result, but if a person is on strong immuno-suppressive therapy, his antibody production may be blocked, which may make test results unreliable.

Why do you ask?: Even the antibody tests from big labs are not altogether sensitive or specific. Many folks have the antibodies but no lesions so probably cannot infect others.

Bx may be sufficient: If you have sores, etc, an actual biopsy and or culture of the sore is definitive enough and good for diagnosis and a blood test would not need to b done in that case. In a monogamous relationship, where the one partner is diagnosed with genital herpes and then the other gets genital lesions, ..An examination and common sense diagnosis can assume with good accuracy the diagnosis too. Best wishes.

1 week: There are two different antibodies that would be associated with a herpes infection. Igm would go up in the first few weeks. Then the igm would fall and igg
would start going up after about a month and it usually stays up. Just have to do the right test at the right time.
