How reliable are genital herpes blood tests vs cultures?

Active vs past. Blood tests can detect exposure to the herpes virus but do not tell if there is active infection. Molecular testing of the affected cells/tissue is more practical than culture for ascertaining active infection.

Do blood tests know the difference between oral herpes and genital herpes?

Yes. You can get serotype-specific testing, but both hsv i and hsv 2 can lead to oral or genital herpes infection, and suppressive drugs for frequent outbreaks have significant overlap. So, although the answer is yes, it may be irrelevant. Read more...
HSV 1 vs HSV 2. Blood tests can find antibodies that are made by the immune system to fight a herpes infection. Antibody tests are done but are not as accurate as a viral culture at finding the cause of a specific sore/ulcer. Antibody tests can't tell the difference between a current active herpes infection and a past herpes infection. Some blood tests can tell the difference between hsv 1 (oral)/hsv 2 (genetal).

Herpes . Herpes is caused by a virus that can lie dormant in the body for years. Because of this, you can catch it from someone who has never even had any symptoms. Since you had a negative test in june and a positive test now, it's safe to say you probably contracted herpes sometime between then and now, but when and from who cannot be determined. Either partner could have transmitted it to you and your outbreak would not have necessarily coincided with when you contracted it. I attached a center for disease control website with information about herpes below. Read more...
Recent infection. ...the nature of symptoms can give a clue. If multiple painful sores, inflamed lymph nodes, and sometimes fever, it's probably a new infection (within 1-2 weeks). Also, if blood test is negative but becomes positive in a few weeks, it's new. Milder outbreaks usually are recurrence of longstanding infection. Make sure virus is types, need to know HSV1 vs HSV2. Partner needs repeat blood test. Read more...

Can a blood test be determined if a man has genital herpes?

Yes and no.... A blood test can tell whether someone is infected with herpes simplex virus type 1 (HSV1) and/or HSV2. It doesn't tell if genital or oral; that requires symptoms and/or testing of an outbreak for the virus. Most HSV1 is oral, some genital; almost all HSV2 is genital. The tests aren't perfect, but if you have symptoms that suggest GH or an infected partner, testing can be helpful. Read more...

If I tested positive for genital herpes blood test when I am asymptomatic is it conclusive?

Yes. The blood test lets us know that you have the virus lying dormant in your body some where. When your immune system is otherwise compromised due to stress, malnutrition, lack of sleep or other infection the virus will come out of hiding and give the classic symptoms of very small, painful/itchy vesicles .
