If you are abstinent, no, you don't need to take it, realizing you could have an outbreak. ...Read more

Depends: If the exposure is within a couple of weeks, IgM would be the test to get. On the other hand, there is no harm if getting IgG which would indicate exposure months or years ago. Unfortunately an infected person, even in the absence of symptoms, may infect other people. Until this situation has been settled, insist on condom use. ...Read more

I had unprotected sex with someone 1 week ago and today she just found out her ex tested positive for hsv2. I went to get a herpes blood test today. Is it too soon to show up? How accurate is it?
Herpes Testing:
It is way too early to be tested from that possible exposure. But, with the new herpes tests you should know your status. We now know that 90% of those with herpes do not have sores and often do not know that they may be infected.
Good 'early' and 'aged' antibody testing for this exposure would be best at about six weeks or so.

My gf had a cold sore on her lips and all the time I was kissing her when I made a herpes blood test it came out IgG postive IgM negative?
Not to worry: Cold sores are caused by herpes virus but the majority of people in the us have been infected & many never get cold sores (even though once you get it it stays in your body). Your test shows you were got herpes long ago but have no sign of recent exposure. You can't catch it from your girlfriend because you already have it. However, she could spread it to your genital region so take precautions! ...Read more

Why?: It's easy to get a herpes blood test--your doctor has just checks the hsv-2 igg box on the order form. There's no need to see an infectious disease doctor, as much as we love your business. However, the test will only tell you whether you have the virus, not whether you need treatment. We only people who have outbreaks, not people with a positive test. Why get tested? It's not a standard test. ...Read more

My dr. Didn't give the herpes blood test because I didn't have sores or discomfort should I had the test. Heard from some 1 that my ex might have it?
Why?: Labs for herpes I and herpes ii antibodies are far from completely sensitive or specific. If you have no symptoms, you're not going to do anything different even if you've met herpes ii, and you can't make others sick. I'm sorry your relationship failed, but you're not tainted. You have other health issues and life is hard enough even if you are fully well. Don't trouble yourself; move on. ...Read more

Elusive germ: The blood test is a specific indicator that you have developed antibodies to a specific germ. Herpes can go into hibernation and not be evident to those who do not have outbreaks. There is also some crossover in the strain of herpes that causes cold sores with the one that causes genital disease. Please discuss your concerns with your doc. If not having outbreaks, I would be aware but not worry. ...Read more
