There Are Two Common Blood Tests Used To Identify Herpes And Theyre Often Misleading
I had a patient once who underwent this test, which was positive, and was told she has herpes, which to her was devastating and life-altering, Friedman says. She burst into tears when I explained the significance or lack thereof with this test, which is very misleading. There are two common blood tests used to identify herpes: IgG and IgM. The IgM test is still used by some doctors even though it has been denounced by the Centers for Disease Control and Prevention . According to the American Sexual Health Association , IgM tests can lead to deceptive results, as well as false assumptions about how and when a person acquired HSV.
And thats not all: IgM tests fail to accurately distinguish between HSV-1 and HSV-2 antibodies, leading them to provide false-positive results for HSV-2. In other words, if youve been exposed to oral herpes , results of the IgM test could lead you to believe youre positive for genital herpes, when in fact you simply have antibodies against HSV-1.
IgG tests, on the other hand, are more accurate, but arent without their own issues. For instance, ASHA says that while an IgG test can distinguish between HSV-1 and HSV-2, the problem is that the time it takes for IgG antibodies to reach a detectable level varies from person to person. This means that even with accurate results, someone could get a false-negative if they have the test administered too soon after contracting the virus .
How To Choose The Right Herpes Test For You
Every herpes test has its own benefits and drawbacks. Its best to discuss your options with a medical professional to make the right choice for your healthcare needs.
It may be helpful to choose your herpes test based on your symptoms. Early in the disease, before a clear herpes outbreak appears, some test methodologies like a PCR test and an antibody blood test can yield false-negative results. On the other hand, a viral culture may yield false-negative results later in the disease.
If you want to receive test results that provide a comprehensive evaluation of your infection, consider using multiple herpes testing methods. If getting a rapid result is your priority, a PCR test is the fastest option.
Polymerase Chain Reaction Test
As with the viral culture, your doctor swabs or scrapes a sample from one of your sores. A lab gets the sample and looks for genes from the herpes virus. PCR test results usually come back to you within 24 hours.
Youre more likely to get this test if you have symptoms but its been longer than 48 hours since they showed up. In this case, you can rely on the results from this test more than the viral culture.

Does My Healthcare Provider Include A Blood Test For Genital Herpes When They Test Me For Everything
Herpes blood tests may or may not be part of the tests your healthcare provider gives you. They may choose tests based on several factors .
They will also evaluate you for signs or symptoms of herpes to choose which tests to use. This is why its important to talk openly and honestly with your provider during your visit. Ask them which infections they are and are not testing you for and why.
When Should I Get Tested
The best time to get tested for herpes if you havent had an initial outbreak is 12 days after exposure. This is because your body will have had time to produce antibodies that can be detected on a test.
A blood test can determine whether you have these antibodies.
Swabs, on the other hand, can detect the virus directly from an active herpes lesion.

How Soon Can I Test For All Stds At Once
We know it can be hard to wait to get tested. As soon as the thought crosses your mind that you may have an STD, you want to learn your status ASAP. But you know now thats probably not the best idea. You dont want to test too early, and you also dont want to have to visit our labs multiple times because of all the different STD incubation periods.
To make it easy and only have to test once, we suggest waiting to test according to the STD with the longest incubation period. For example, If you wanted to test for everySTD mentioned on this blog post using our comprehensive 10 test STD panel, you would need to wait at least eight weeks to get accurate results, because that is the minimum amount of time hepatitis C needs before it shows up on tests.

Herpes Pcr Tests Very Accurate
A PCR test can be done on cells or fluid from an active sore and is more sensitive than typical lab culture tests. PCR finds the genetic material of the HSV virus and can tell the difference between HSV-1 and HSV-2. Although this test may be more expensive than lab cultures, it is definitely more accurate and less likely to result in a false negative or false positive. However, you still need to get tested while you are having an active outbreak, or else the HSV cells may no longer be present on the surface of your skin.

Herpes Lab Cultures Only Accurate Some Of The Time
Many doctors and health care professionals are not up-to-date about herpes diagnosis and will tell you that the only way to accurately diagnose whether or not you have the genital herpes virus is by taking a swab from an active herpes sore or lesion and sending it to the lab for a culture test. However, this only works if the patients sore is fairly new or else the virus may no longer be active on the skin. If you get a Herpes Lab Culture and it comes out negative, you may still have genital herpes. Because most herpes outbreaks are short and mild, and because most people have few, mild or even NO outbreaks, we highly recommend taking a herpes blood test when no active sores or lesions are present, and in ADDITION to a Herpes Lab Culture when there is a sore present.

What To Expect From An Hsv
HSV-2 testing should be conducted between four and six weeks after potential exposure.
When the body is infected with HSV-2, it produces antibodies to help fight the infection, called immunoglobulin G . The HerpeSelect® Herpes Type 2 Test is used to identify IgG in the blood. The HerpeSelect® Herpes Type 2 Test is 97 to 99 percent accurate between four to six weeks post-exposure and remains 99 percent accurate after 6 weeks post-exposure. Its important to wait at least four weeks after exposure, because it takes time for the body to develop antibodies that are detected by a blood test. The HerpeSelect® Herpes Type 2 Test detects HSV-2, even when there are no symptoms and the infection is not active.

How Common Is Genital Herpes
Genital herpes infection is common in the United States. CDC estimated that there were 572,000 new genital herpes infections in the United States in a single year.1 Nationwide, 11.9 % of persons aged 14 to 49 years have HSV-2 infection .2 However, the prevalence of genital herpes infection is higher than that because an increasing number of genital herpes infections are caused by HSV-1. 3 Oral HSV-1 infection is typically acquired in childhood because the prevalence of oral HSV-1 infection has declined in recent decades, people may have become more susceptible to contracting a genital herpes infection from HSV-1. 4
HSV-2 infection is more common among women than among men the percentages of those infected during 2015-2016 were 15.9% versus 8.2% respectively, among 14 to 49 year olds. 2 This is possibly because genital infection is more easily transmitted from men to women than from women to men during penile-vaginal sex. 5 HSV-2 infection is more common among non-Hispanic blacks than among non-Hispanic whites . 2 A previous analysis found that these disparities, exist even among persons with similar numbers of lifetime sexual partners. Most infected persons may be unaware of their infection in the United States, an estimated 87.4% of 14 to 49 year olds infected with HSV-2 have never received a clinical diagnosis. 6
The age-adjusted percentage of persons in the United States infected with HSV-2 decreased from 18.0% in 19992000 to 12.1% in 2015-2016. 2

How To Read Your Results
Your HSV test results will likely be reported as negative or positive :
- Negative. The herpes virus was not found. However, you may still have an HSV infection if your results were negative. It may mean the sample didnt have enough virus to be detected. If you still have symptoms of herpes, you may need to order another test.
- Positive. HSV was found in your sample. It may mean you have an active infection or contracted the virus in the past .
If your test results are positive for HSV, talk with a doctor about your next steps.
