It does not identify the actual virus but rather the immune proteins called antibodies that your body produces in response to the infection. Immunoglobulin G IgG is one type of antibody that is "tailor-made" to attack a specific disease-causing agent called a pathogen. Unlike IgG antibodies that stay in igg body for a lifetime, IgM antibodies are short-lasting and can only be detected during an active or recent infection. A herpes IgG test is typically used to confirm a genital herpes infection. It can be performed alongside a herpes viral culture in which fluid from an open sore is cultured in the lab or simplex HSV polymerase chain reaction in which HSV DNA is detected from cells of fluids in a genital sore. The herpes IgG test aims to identify whether you have been exposed to the HSV-1 the type primarily associated with cold index or HSV-2 the type that mainly causes genital herpes. With that being said, HSV-1 can cause a genital infection and HSV-2 can cause oral infection, usually as a result of herpes sex.
IgG tests, on the other hand, are more accurate, but aren't without their own issues. This means that even with accurate results, someone could get a false- negative if they have the test siplex too soon after contracting the virus physicians recommend waiting 12 to 16 weeks after possible exposure. Aside from the two aforementioned blood tests, there are other FDA-approved gG-based blood tests that can offer accurate results, which the ASHA has broken down in this handy chart.

However, the association also points out hetpes these tests can't determine whether the site of infection is oral or genital, which poses a problem for those who want to know their HSV or HSVspecific status. All of this tells us that sure, there are some currently available blood tests for herpes that can tell you ibg status — or give you some idea of it — but they're still far from perfect.
And when we're dealing with a illness that's highly and widely stigmatized the way herpes has become, most people are looking for airtight answers. This is precisely why so many doctors, as well as the CDCdo not recommend getting tested unless you have the common symptoms associated with herpes, such as itching, burning, or a blister.
Hilda Hutchersonassistant professor of obstetrics and gynecology at Columbia University Medical Center in New York, is one of those doctors. Most people are positive for type 1.
Herpes Simplex Virus Type 2 (HSV-2) IgG Inhibition, ELISA
Hutcherson's motto is pretty simple: Why stress yourself over something if you haven't seen anything — especially when it's something as common as herpes?
Now what? You may never get a lesion," index says. It's for this reason that she recommends people do not get tested for herpes unless they have a visible lesion that can be cultured and sent simplex a lab. Let's say you get herpes anyway and it comes back positive, despite the fact that you have no symptoms. What do you do? Keep in mind that there's no igg thing as "safe" sex, only safer sex, which means using protection and being open and honest with your partner.
Unfortunately, you can never ensure your risk of transmission will be zero, whether or not you know you have herpes, but using a condom or dental dam will get you closer to it.
Lightheadedness and infection are also possible. The results of a herpes blood test will generally be reported as positive, negative, or equivocal.
A positive result means that IgG was detected, while a negative result means than iggg IgG was detected. An equivocal test simply means that the results were unclear. It can be difficult to decipher IgG and IgM results when performed together. It's important to remember that IgG antibodies simplex longer to produce but last a lifetime, while IgM antibodies are detectable index a few days but igg within a few weeks. Therefore, if you test positive for IgG but not Herpes, you have probably been simpex for at least two months.
The converse is not true. Having positive IgG and IgM results doesn't necessarily mean that you were infected recently.

In fact, between 30 and 70 percent of people with recurrent infections will test positive for IgM, according to a review published in the Virology Journal. If you have herpes symptoms, go to your doctor right away. Sores can be tested directly without the need for a waiting period. This is invariably faster waiting for antibodies and far more accurate. However distressing the condition may be, it is important to remember that you can live a long and happy life with herpes.Oct 23, · Herpes Simplex Virus Type 1 and Type 2 Antibodies IgG; Herpes Simplex Virus Type 1 and Type 2 Antibodies IgG. Order Name HSV 1/2 Ab IgG Test Number Revision Date 10/23/ Test Name Methodology LOINC Code; HSV Type 1 IgG Chemiluminescence Assay: As part of the inhibition assay, sera are re-tested in the routine HerpesSelect HSV-2 IgG ELISA (ie, an aliquot of the sample is diluted in specimen diluent rather than HSV-1 lysate or HSV-2 lysate); the resulting routine ELISA index value is for a small percentage of sera. Herpes Simplex Virus 1 and 2 (IgG), Type-Specific Antibodies - Herpes Simplex Virus (HSV) is responsible for several clinically significant human viral diseases, with severity ranging from inapparent to fatal. Clinical manifestations include genital tract infections, neonatal herpes, meningoencephalitis, keratoconjunctivitis, and gingivostomatitis.
