What is the maximum window period to detect antibodies for herpes in blood tests?

What is the maximum window period to detect antibodies for herpes in blood tests?

Many, many years: Once infected, the virus hides out indefinitely. This constant presence makes the immune system continually produce the igg type of antibody to the virus. During the initial stages of the infection, your body makes the igm type of antibody, but this eventually is superceded by igg within a few weeks. Thus: 1st few days=igm+ igg-. After couple weeks=igm+igg+. After several weeks to years=igm-igg+. ...Read more

How accurate are the herpes tests?

How accurate are the herpes tests?

Depends on the test: So we have a couple of tests. One is a polymerase chain reaction test (PCR) for herpes that we get when we scrap the lesion. Another test is a blood test that detects the body's antibody response to an infection by the Herpes Virus.Regarding the PCR test it is very accurate but it depends on getting a good DNA sample from the scraping. The blood test depends on the antibody response time. DNA better. ...Read more

Are false positive herpes test likely?

Are false positive herpes test likely?

No: A positive antibody means you're infected with herpes. That doesn't mean you're developing outrbreaks, but it does mean that you at least have latent herpes somewhere in your body. A positive culture or pcr for herpes means you have an active lesion. ...Read more

Can they pick up dormant herpes 2 on a test?

Can they pick up dormant herpes 2 on a test?

Yes: Blood tests can diagnose herpes simplex virus type 1 (HSV1), the usual cause of oral herpes, and HSV2, the main cause of genital herpes. Have an IgG antibody test only. IgM testing often done but is unreliable, often misleading, not recommended by herpes experts. But beware: even IgG testing can be misleading. Get tested only if recommended by a doctor experienced in herpes and testing for it. ...Read more

If a herpes culture/test is negative, how accurate is that result?

If a herpes culture/test is negative, how accurate is that result?

Depends on timing: False negatives can occur, especially if the ulcer is cultured too late, after healing has already begun. False negatives are less likely to occur when the culture is taken from an intact vessicle (blister) that has been opened for the purpose of the culture, or from a very fresh ulcer. ...Read more

Is a culture test more accurate then a igg herpes test or should I do both?

Is a culture test more accurate then a igg herpes test or should I do both?

Herpes: No; Cell culture or PCR test may give a false-negative result if the sores have begun healing or if you are recently infected. It takes several weeks for HSV antibodies to show up in the blood. PCR and cell culture tests show that you have been exposed to the virus at some point. Your doctor may choose to do both or neither based on the physical examination. ...Read more

I have genetial herpes but in my test results it is only positive for type1and not type2 way is that?

I have genetial herpes but in my test results it is only positive for type1and not type2 way is that?

Herpes is a virus: This is a common story. This is why we now use type 1 and 2 instead of 'oral and "genital' herpes. This virus does not know geography. You get herpes where you get herpes. It is just generally that the majority of those with type one have it close to their mouths and most with type two have it somewhere between their belly buttons and thighs. ...Read more

What kind of test to check for herpes? And how accurate it is? What are the consequences of a positive herpes?

What kind of test to check for herpes? And how accurate it is? What are the consequences of a positive herpes?

Two test types: There's an antibody test for herpes (hsv-2 igg), but it only tells you whether you have herpes in your body; it doesn't tell you whether a skin or genital lesion is due to herpes. For that you need a viral culture or pcr from a fresh lesion. We generally treat based on symptoms, not based on antibody status, so the antibody test is not widely used. ...Read more

Is there a test where doctors can date herpes to the first out break? I got it from my bf but want to prove he had it first.

Unfortunately not: There is really no test that can determine when the first outbreak occurred. It can detect the evidence of antibodies against the virus and whether the infection is acute or whether one has been exposed to the virus before. ...Read more

Was diagnosed with herpes 2. Number 1.6. Took the test again a year later same number. Could the results be a false positive?

Was diagnosed with herpes 2. Number 1.6. Took the test again a year later same number. Could the results be a false positive?

Herpes virus 2: The blood test has very little meaning unless you have symptoms of the disease. This is a very complicated problem and your doctor can explain it all to you. All the test means is that you have been exposed to the virus and now are a carrier of the disease. Please have your doctor explain more to you and you have no need for this blood test ever again in my opinion. ...Read more

Neg herpes test 4months post exposure. What is the chance it would be neg due to IgG levels being low if I was having a recurrence?

No: Do you mean your total igg level being low or just to the hsv? If total igg is normal, then a low anti-hsv igg likely means that you have had no recent exposure. ...Read more

IKnow this'll sound crazy. But is there a way to test my husband for herpes without him knowing? He will refuse&lie if I ask him2....

Sorry, no way: This isn't crazy at all. However, it is unethical (and in some situations maybe illegal) to test someone without saying what the test is for. If you have herpes or think you might, you'll need to speak with your husband about it. Find a doctor with expertise in herpes and other STDs, or a clinic like public health or Planned Parenthood. They'll have advice about how to discuss it with him. ...Read more

Could I take a test at home for herpes type 1 I got tested positive but I've been dealing with my girlfriend for 7 months and she don't got its hard?

Could I take a test at home for herpes type 1 I got tested positive but I've been dealing with my girlfriend for 7 months and she don't got its hard?

No: Cold sores on or near the lips are usually caused by herpes type 1 virus. Most people get them not through sex, so they are not considered an STD. However, they can be transmitted through sexual activity. Genital herpes is usually caused by herpes type 2. Through oral sexual activities, she can get oral herpes 1 sores on her genitals if she has never had herpes 1. One's doctor can help solve this. ...Read more
