if your symptoms are due to herpes.

It may take between six and eight weeks to detect antibodies in a herpes blood test after first becoming infected with HSV.

Also, antibodies may disappear with time, especially if the person has infrequent recurrences of herpes..

How long does it take for HSV IgM to convert to IgG?

There are a number of factors important to consider and understand though, when it comes to serologic testing for HSV antibodies. First, IgM antibodies typically become detectable about 10 to 21 days post infection, with IgG-class antibodies developing around the same time.

Can HSV 2 IgG be wrong?

False positive results can occur with many diagnostic tests, including STD tests. The chances of false positive results increase as the likelihood of the infection decreases in the person being tested. False positive HSV-2 results can happen, especially in people who are at low risk for a herpes infection.

What does it mean if you have HSV 2 antibodies?

This test is done to detect if a person has been infected with the herpes simplex virus (I or II). This test does not detect the virus itself. If antibodies to the virus are present, the person has been infected with herpes simplex at some point in his or her life.

What does it mean if your IgG is high?

High levels of IgG may mean a long-term (chronic) infection, such as HIV, is present. Levels of IgG also get higher in IgG multiple myeloma, long-term hepatitis, and multiple sclerosis (MS).

What is the difference between HSV IgG and IgM?

IgG appears soon after infection and stays in the blood for life. IgM is actually the first antibody that appears after infection, but it may disappear thereafter.

Does IgG or IgM come first?

IgM antibody appears first, followed by IgA on mucosal surfaces or IgG in the serum. The IgG antibody is the major antibody of the response and is very stable, with a half-life of 7 to 21 days.

What does HSV IgG negative mean?

IgG is made after the IgM antibody and typically will be present in the bloodstream for the rest of your life. A negative test result is considered normal. This generally means that you’ve never contracted an HSV infection.

What does HSV IgG positive mean?

A positive HSV-1 or HSV-2 IgG antibody test means antibodies are present in your blood, which means you have had an infection in the past even if you haven’t noticed any symptoms. The type of antibody detected indicates the type of HSV infection.

How accurate are HSV IgG tests?

Herpes blood tests are actually pretty accurate. That’s particularly true for the type-specific tests that are most often recommended. In a relatively high prevalence population, they give accurate results the vast majority of the time.

What does it mean if you have HSV antibodies?

The herpes simplex virus antibodies test screens for current or previous HSV infections. In some cases, the HSV antibodies test can be used to diagnose an active HSV infection. But more often, a herpes culture is used. The antibodies test is valuable because many early herpes infections show no symptoms.

What is normal IgG range?

Normal Ranges Adult: IgG 6.0 – 16.0g/L. IgA 0.8 – 3.0g/L. IgM 0.4 – 2.5g/L.
