Herpes Ig G False Positive
Herpes' IGG result 17.40 at 5th week after exposure - can one get that high result? Or could it be false positive? Should I rest to confirm? When?
Need more info: You don't mention which Herpes virus you were exposed to and what the exposure was. The high IgG titer may be correct. Many adults have IgG antibodies to Herpes simplex virus type 1, with or without overt infection. Most, but not all, genital infections are due to Herpes simplex type 2. However, type 1 can cause genital infections as well. ...Read more

Chances of having a false positive herpes type 1 blood test? 9.1 igg. While other STDs remain negative 0.0 igg. Had my test 2 weeks later after exposure.
True positive, but: As pointed out, many adults are positive for Herpes simplex type 1 by adolescence. New IgG antibodies usually ae being produced by day 10 after exposure, may not be detectable until 3 weeks, occasionally later. Particularly diseases such as syphilis and HIV may not be positive at 2 weeks. You should be retested at 4 weeks. HIV ...Read more
If I had a positive IgG herpes blood test but never had Symptoms Why would the doctor tell me it is probably a false positive? Did he cross reference?
It depends...: This depends on details you don't mention. If definitely positive (e.g., if you had a HerpeSelect IgG test and the HSV2 value is 3.5 or higher), it's not false positive: you are infected with HSV2. Lower numbers can be false positive, however. For HSV1, false positive are very rare; if positive, you're infected. ...Read more
Is lab results always right? Had hsv1 many times results say hsv1 IgG >5.00 but hsv2 IgG says 1.25 can there be false positive for hsv2?
False + can occur: Especially if you are positive for HSV1 there can be a false positive for HSV2. Ask your doctor to order a Western Blot test for HSV2 - that is the gold standard test. If that is negative, then you can be sure that you do not have HSV2. ...Read more
Could having a flu or cold when your blood is drawn cause a false positive on a Hepatitis A IgM test? Igg was negative.
Very possibly: As you know, the hepatitis A IgM antibody tests for recent infection. False positives may result due to the presence of cross-reactive antibodies from other viral infection or underlying illnesses. Depending on the circumstances and time of exposure, retesting should be considered. Best wishes:) ...Read more
What are the chances of a reactive Hepatitis A IgM antibody test being a false positive? Igg test was negative. Can you get a false positive if you've got a cold or flu when the test is run?
Maybe: Lab error is always a possibility. For now, assume you have hepatitis A, practice good hygiene, and go about your activities as you are able -- as if you really had it. Best wishes. ...Read more
Some viral shedding: Although the chance of transmission is highest during an active outbreak, there is still a very small chance of transmitting/spreading the infection without outbreak as some viral shedding occurs all the time. If you have frequent outbreak, consult your doc for suppressive treatment as there are quite a few options available these days. Good luck. ...Read more
I tested positive for herpes II IgG on june, I got tested again in august and it came back negative, am I positive or negative? No symptoms here.
IgG mature antibody: Yes, but surprising. If you have no other blood test history then we cannot really tell you that an exposure eight weeks is the one that infected you. Igg antibodies are the mature antibodies and usually take more time. ...Read more
Both husband and I ttested positive for herpes 1 IgG and herpes 2 indeterminate, igg. What does that mean? Who is the carrier? How do u get herpes
Here is the best we can do today. If the igg is indeterminate then your physician must order the herpes western blot test. Knowing if you have hsv two if vital.
Herpes is two separate viruses. Type one, the 'oral' herpes or 'simplex' herpes is found in 75% of americans and is usually transmitted to one during childhood.
Herpes type two or hsv is thought to be the std version. Skin to skin. ...Read more

Can I trasmit the dieseas if I tested for herpes IgG positive and IgM negative they told me I don't have herpes and I showed no symptoms in the past?
Am I herpes negative or positive? HSV 2, IgG result is 1/80 (Ref Range Negative is < 1/40), HSV I, IgG result is 1/80 (Ref Range Negative is < 1/40).
Probably yes, but...: I'm not familiar with HSV blood tests that give results as fractions or titers. With other tests (e.g. HerpeSelect®), any positive HSV1 result usually is valid, but weakly positive results (which is what I suspect is how to interpret your HSV2 result) often are false and require confirmation. In most countries, over half of adults are HSV1 positive, no big deal. But you'll need to clarify HSV2. ...Read more
I got a 1.07 for a HSV 2 IgG test. I was positive for HSV 1. What should I do next? Do I have herpes?
Reference range: Is the value 1.07 higher than the normal range for the lab that did the test? If yes, you are infected with HSV 2. Herpes viruses, both HSV 1 and 2, live in the nerve endings forever and a person can pass it on to others even if there are no visible lesions. You may wish to consult an infectious disease specialist for proper diagnosis and treatment. ...Read more
HSV 1 and 2 IgG are negative but HSV IgM I/II combination came back positive at 2.28. Do I have herpes?
The Ig M titer is the titer that shows initial infection, with time it will change to a positive IgG.
These of course are lab values. If you have symptoms then it is confirmation of HSV. HSV 1 is oral or common lip blisters. HSV2 is genital herpes. Unusual that both HSV 1 and 2 are turning positive at same time. In any event both are ubiquitous in the population. ...Read more
Herpes 1 IgG positive. Have no symptoms at mouth. Herpes II IgG indeterminate. What does this mean. How did I get herpes 1?

Herpes simplex: Herpes simplex is transmitted by direct contact with a lesion or the body fluid of an infected individual.Transmission may also occur through skin-to-skin or mucous membrane contact during periods of asymptomatic shedding. Barrier protection methods are the most reliable method of preventing transmission of herpes, but they merely reduce rather than eliminate risk. ...Read more
Do I infect other if I tested for herpes blood test IgG positive 158 and IgM negative 0.08? And what negative IgG means? Thank you
How long before having sex with an herpes infected partner can an IgG test come positive? 2 weeks or a month? Or more than a month
The herpes virus can occasionally be spread when there are no symptoms due to a phenomena known as viral shedding.
It is possible for a person to carry the herpes virus without knowing that they have it, in fact, up to 80% of people who are infected with hsv-2 show no signs of the infection. So it is possible for a person to unwittingly transmit the infection to their partner. ...Read more
I had herpes blood test 1&2 IgG positive 158 IgM negative 0.08 they told me I don't have herpes are they correct? I'm so confused please help me
Yes: They are correct. Igm tells us if you have an acute or active infection. This was negative, so you do not. The igg tells us you have previously been exposed or infected. This was positive, so you have. ...Read more
Neg. Igm for herpes 1and 2. Positive IgG for herpes 1 and neg.2. I have blisters but culture came back neg. Who do I believe? What is a good test
No acute infection!:
negative igm and negative culture suggest that there is no acute infection. Positive igg shows that you have had past infection. Both tests agree in your case. There is another test polymerase chain reaction (pcr) which has been widely used recently. Tzanck smear shows the presence of herpes virus also. Rarely, more than one test is ordered by your physician - it could be expensive. ...Read more
My Gyno did some blood wrk to chk for herpes I believe igg hsv1 & hsv2 came bk positive. I've only been w/ one man my husband how did I get hsv2?
Tricky herpes: The truth is, herpes has been affecting us humans for a long time-and so it's actually 'adapted' to us. In other words, it doesn't always cause a terrible flare up of herpes rashes. In fact, only 5% of all patients who are infected have symptoms. That means the other 95% may not have anything-just the virus is there, going along for a free ride as viruses are known to do. Talk to your GYN about it ...Read more
