There Are Two Common Blood Tests Used To Identify Herpes And They’re 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 that’s 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 you’ve been exposed to oral herpes , results of the IgM test could lead you to believe you’re positive for genital herpes, when in fact you simply have antibodies against HSV-1.

IgG tests, on the other hand, are more accurate, but aren’t 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 .

  • What Is The Herpes Simplex Virus

    The herpes simplex virus is a type of virus that causes infections in humans. Approximately 3.7 billion people under the age of fifty â or 67% â have been infected with HSV-1 in their lifetimes. There are about 491 million cases of HSV-2 worldwide â or 13% of the global population between the ages of 15 and 49.

    HSV is spread through direct contact with the virus. This can happen during sex or while giving birth.

    The virus leads to an increased risk of infection with human immunodeficiency virus . It can also cause you to develop more severe conditions if you have a compromised immune system.

    HSV can have particularly problematic results if youâre infected with the virus when youâre born. The chance of passing it on while pregnant is low but â if it happens â it can lead to disabilities and death.

    Thereâs also a social stigma associated with this virus that can be damaging to your mental health if you ever become infected.

    Genital Herpes Is Common Why Doesnt Cdc Recommend Testing Everyone For This Std

    CDC does not recommend herpes testing for people without symptoms. This is because diagnosing genital herpes in someone without symptoms has not shown any change in their sexual behavior nor has it stopped the virus from spreading. Also, false positive test results are possible. Even if you do not have symptoms, you should talk openly and honestly about your sexual history with your doctor to find out if you should be tested for any STDs, including herpes.

    Although CDC does not recommend that everyone get tested for herpes, herpes testing may be useful in some situations. Herpes blood tests might be useful

    • If you have genital symptoms that could be related to herpes,
    • If you have a sex partner with genital herpes, or
    • If you want a complete STD exam, especially if you have multiple sex partners.

    Please note that while a herpes blood test can help determine if you have herpes infection, it will not be able to tell you who gave you the infection.

    What Can I Do About Genital Herpes

    So heres the good news: herpes is rarely a serious health issue. Although there can be a negative stigma associated with those who have an outbreak and the blistering sores may change sexual habits, a majority of those infected have no symptoms at all.

    If you do request a herpes blood test, ask if your doctor is going to be performing a type-specific test. These blood tests tend to be more reliable.

    Should the blood test come back as positive, how your treatment plan develops will depend on other health conditions that may be affecting you. Suppressive therapies and other medication may be ordered, but in some patients, careful watching and waiting may be the best solution. If suppressive therapies are ordered, this will mean taking a drug every day that youll have to pay for.

    Genital herpes can be detected with a herpes blood test. If no symptoms are being experienced, your doctor may wish to hold off on testing to avoid a false positive. And, if youre concerned about your sexual health for any reason, schedule an appointment with your doctor right away.

    Testing With No Symptoms

    Blood tests can be used when a person has no visible symptoms but has concerns about having herpes. Blood tests do not actually detect the virus instead, they look for antibodies in the blood.

    IgM vs. IgG

    When an individual contracts herpes, the immune system responds by developing antibodies to fight the virus: IgG and IgM. Blood tests can look for and detect these antibodiesnot the virus itself. 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.

    IgM tests are not recommended because of three serious problems:

    The accurate herpes blood tests detect IgG antibodies. Unlike IgM, IgG antibodies can be accurately broken down to either HSV-1 or HSV-2. The challenge here is that the time it takes for IgG antibodies to reach detectable levels can vary from person to person. For one person, it could take just a few weeks, while it could take a few months for another. So even with the accurate tests, a person could receive a false negative if the test is taken too soon after contracting the virus.

    For the most accurate test result, it is recommended to wait 12 16 weeks from the last possible date of exposure before getting an accurate, type-specific blood test in order to allow enough time for antibodies to reach detectable levels.

    Is It Possible To Get A False Positive Result

    A false positive is when a test says you have a condition that you actually don’t have. This can happen with the herpes IgM blood test.

    In some cases you may not be infected at all. However, you may have a different virus that triggers a positive on this blood test. This may include the Epstein-Barr virus, which is in the herpes virus family, or parvovirus, a contagious virus that can lead to flu-like symptoms.

    If you don’t have symptoms, you may want to go back for IgG testing at a later date. If you do have symptoms, your healthcare provider can test the sores for herpes directly with a swab test.

    A positive result is more likely to be accurate if you have or have had symptoms of a herpes outbreak.
