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

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

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 moreSee 1 more doctor answer
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.

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.

I had protected sex with my partner he has herpes no signs nor symptom. I did an IgG test few weeks after tested positive for hsv1&2 how is that?
This means in 100% certainty that you were exposed to herpes prior to this exposure from your partner.
Herpes infections do not necessarily have to be on the penis or in the vagina. Thus condoms do not protect against the skin to skin transmission of the herpes virus.
But, to have igg antibodies you have to have been exposed months before at least. ...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
