Is it possible to have a false positive on a herpes test? And do you know how long its suppose to take for the blood test results to come back?

Is it possible to have a false positive on a herpes test? And do you know how long its suppose to take for the blood test results to come back?

False pos can occur: The standard blood tests for herpes simplex virus (HSV) are not perfect; false positive results can occur. The strength of the result -- i.e. the optical density ratio (also called ELISA ratio) -- is important in distinguishing true positive from false psotive results. Results usually are available in 2-5 days, but it varies a lot from one lab to another. ...Read more

History is key: Without a sore or a typical herpes lesion, I wouldn't even believe a positive blood test as evidence that you're clinically ill with herpes II. The labs aren't 100% for either strain. ...Read more

Been married 4 years. No cheating. If I test positive for genital herpes in blood test, is it worth it to take medication if we are asymptomatic?

Been married 4 years. No cheating. If I test positive for genital herpes in blood test, is it worth it to take medication if we are asymptomatic?

No, don't: Antibodies to genital herpes do not mean that you have an active infection. Frequently, old serological tests cannot distinguish between hsv1 and 2. Its a possibility that you have an infection that is silent and can transmit virus. So, be cautious and use protection during intercourse. ...Read more

Prescribed Valtrex (valacyclovir) bc I tested positive for HSV2 antibodies blood test, but no outbreak - ok to to take even if I may not really have genital herpes?

Prescribed Valtrex (valacyclovir) bc I tested positive for HSV2 antibodies blood test, but no outbreak - ok to to take even if I may not really have genital herpes?

It depends: Valtrex (valacyclovir) is to prevent outbreaks to protect you from them and your sex partner. You may still be infectious even when there are no symptoms of an outbreak yet. If you have been monogamous, the same sex partner, it may not be necessary to take it. Have them tested and discuss with your doctor. If you are abstinent, no, you don't need to take it, realizing you could have an outbreak. ...Read more

Should I take igm & igg blood test for Hsv if exposed to g herpes but no outbreak, have other symptoms, and had mouth cold sores in the past. Advice?

Should I take igm & igg blood test for Hsv if exposed to g herpes but no outbreak, have other symptoms, and had mouth cold sores in the past. Advice?

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

You: You are right, it could represent an allergic reaction or it could be from herpes. A type of a severe allergic reaction called stephen johnson syndrome can cause lesions (sores) on your mouth. Please be seen immediately and be evaluated for this.

If you are having itching, any shortness of breath, nausea or vomiting, or rash then you need to be seen as an emergency. ...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?

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. ...Read more

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?

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

Tested for stds, all negative, months after unprotected sex, I want a herpes blood test but hard to get, do I ask for referral to infectious disease dr?

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
