What is the test result range for both negative & positive for HSV antibodies IgM & igg? Ex. <0.9 ... Etc

Differs by lab: What you are asking is for the normal "reference ranges" for these tests. Reference ranges are established by each laboratory based on their testing equipment and vary from lab to lab. There is no universal reference range for these or other lab tests. You would need to ask for the range at the lab where the tests were run. ...Read more

I was told that I tested positive for IgG antibodies for I believe he said HSV 2. However he insisted that I did not have the virus and I was exposed.

I was told that I tested positive for IgG antibodies for I believe he said HSV 2. However he insisted that I did not have the virus and I was exposed.

Peek-A-Boo: Ouch!!: Yes, technically you've been' exposed' in the past and your immune system responded. And you don't "have" it in the sense that you have no symptoms right now. But that virus is notorious for hiding in you and then coming back out some time(s)and look like a new infection (called a "recurrence").If you can't remember any Herpes infection in the past, that can happen.It was mild or un-noticed by you ...Read more

My doctor just told me she has seen patients go from having tested positive 4 HSV 2 antibodies to negative in their lifetime. Is this possible or no?

Absolutely: These tests are fraught with pitfalls, both in performance and interpretation, and sometimes the antibodies disappear. As a pathologist and laboratory physician, i constantly remind others, "the most helpful test is the history and physical exam." let this, not a lab value, guide your treatment decisions. ...Read more

Is it possible to test positive for hsv-2 antibodies but not actually have it or spread it? I have never had an outbreak but I do have hydronitis

Is it possible to test positive for hsv-2 antibodies but not actually have it or spread it? I have never had an outbreak but I do have hydronitis

Yes: First, the test may be falsely positive. Second, if you do carry the virus, it may be oral instead of genital. Third, if it's genital, you may not necessarily have an outbreak or shed the virus, thus transmitting it. There is no means of predicting the course. ...Read more

The IgG test for HSV-2 was positive for antibodies. My pediatrician said I was exposed. Does this also mean I'm infected, and potentially contagious?

Incomplete info: HSV 2 can either represent prior exposure to and experience with cold sores or genital herpes. The strain is not specific to one site or the other.You may know if you had signs of either and you could pass the germ during an outbreak with either (and maybe other times too). ...Read more

I have hsv-1 antibodies in my blood. What does that mean? Am I immune to getting herpes?

I have hsv-1 antibodies in my blood. What does that mean?  Am I immune to getting herpes?

Past exposure: First, remember that hsv-1 is actually quite common as this is the comon "cold sore" on the lip. The antibody in the serum simply implies past exposure. No-one is "mmune" to herpes as the virus can reactivate at times. It is possible for hsv-1 to present as genital herpes, but this is less common as hsv-2. ...Read more

Question about hsv-1 or hsv-2 IgG antibody detection; can it tell you which part of the body the HSV is in?

Question about hsv-1 or hsv-2 IgG antibody detection; can  it tell you which part of the body the HSV is in?

Not really: The lines separating these two types are really kind of blurred. Particularly, when it comes to treatment, the discussion is not all that relevant. It is thought that the virus lays dormant in the dorsal root ganglia of the spinal column. ...Read more

I have had hsv-1 orally since i was young. Do the antibodies provide some protection from it migrating to my genitals or other parts of my body?

Doesn't migrate: The majority of people have oral herpes 1, and it normally does not migrate to other areas. Most people with oral cold sores don't get cold sores elsewhere, although they can catch herpes 2 in the genitals (or other places) even though they already have herpes 1. If cold sores are frequent or bad, just ask the doctor for preventive medicine (an antiviral drug to prevent the cold sores). ...Read more

Confused: some doctors say that HSV 1&2 antibodies show up reliably in 4-6 weeks; others say much, much longer. Which is it?

Confused: some doctors say that HSV 1&2 antibodies show up reliably in 4-6 weeks; others say much, much longer. Which is it?

Depends on test: IgM tests develop in a few weeks but do not differentiate hsv1 from hsv2 and then become neg after a few months in many cases. IgG test is preferable, will differentiate type 1 from type 2, is often pos at 2 weeks, stays pos for life, but does not show for several months sometimes. So it varies with the case and varies with the test. ...Read more

I have always had HSV 1. What are the chances of me catching it genitally through oral? Would the antibodies in my body prevent me from catching it?

I have always had HSV 1. What are the chances of me catching it genitally through oral? Would the antibodies in my body prevent me from catching it?

Cold Sore: Cold sores are caused by certain strains of the herpes simplex virus (hsv). You get the first episode of herpes infection from another person who has an active lesion. Shared eating utensils, razors and towels, as well as kissing, may spread hsv-1. Oral sex can spread hsv-1 to the genitals and hsv-2 to the lips. They usually go away within two weeks. If they haven't see a dermatologist. ...Read more

Is 10wks after possible exposure to HSV 1&2 enough time for antibodies to appear in blood? I've heard reliably 4-6wks it should appear. Some say 24wks

Viral Antibodies: The range can be frustrating. You could have early antibodies in two to three months but aged and mature antibodies can take up to 24 months if you look at the whole population. Sometimes you will get a sore sooner than the antibodies appear. If you get a sore then they can culture this for the herpes viruses. ...Read more

If tested for HSV 1 and 2, would IgM antibodies be detected if infection was from months ago?

Yes: Remember that these tests are still far from 100% sensitive / specific. The results are most meaningful in conjunction with the clinical picture but can also warn (hsv2) of latent infection that never expresses itself. ...Read more
