What Do My Test Results Mean
There are two possible antibodies that your body can make to HSV-1 and HSV-2. These are IgM and IgG.
IgM is the antibody that is made first and typically represents a current or acute infection, although this may not always be the case.
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 youve never contracted an HSV infection.
However, its possible for your results to come back negative even if youve contracted the infection within the past few months. This is referred to as a false negative.
Your body will typically take several weeks to develop IgG antibodies to HSV.
If youre tested earlier in your infection, its possible to have a false negative result. Your doctor may recommend that you return in 2 to 3 weeks to be retested.
A positive test result for HSV-1 or HSV-2 indicates that youve contracted either virus at some point.
The results also allow your doctor to differentiate between HSV-1 and HSV-2, which isnt always possible by visually examining the sores.
Depending on your results, you and your doctor can discuss ways to treat and prevent the transmission of your HSV infection.
When a serum antibody test is recommended for HSV, IgG detection is preferred. In fact, some laboratories are discontinuing their IgM tests in the future.

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.
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.

When Should I Talk With A Doctor About Herpes
If you have a primary care doctor who you regularly visit, you can share your results with them to provide better insight into your next steps.
If you dont have a primary care doctor, you can consult with a physician or nurse from the testing site about treatment options.
If youve been treating your symptoms with medication and are still in pain or discomfort, reach out to a healthcare professional.
Why Is Testing Recommended Only In These Areas
When a herpes outbreak occurs, the blistering and rawness that appears around the genitals, rectum, or mouth can be very painful. The sores which appear when an outbreak occurs can take weeks to heal properly. The herpes blood test can provide your medical provider with information about what can be expected in the future. This would include what medications would be necessary to control symptoms and how you could lower the risks of spreading the infection to a partner.
If you know that you have or had a sexual partner with genital herpes, this testing can tell if you also have the virus. For women who are pregnant, this blood test is very important because the fetus can become infected with HSV-1 or HSV-2 if the mother is infected. This can place the pregnancy at risk and in babies, a herpes infection can even be fatal.

Is One Virus Better Than The Other
Although incurable, both viruses are treatable and manageable in day-to-day life. Beyond this fact, each persons body chemistry and immune system are unique, and although the virus strains have their preferences, they are not set in stone. Developing awareness of your own body and becoming educated about the herpes simplex virus strains can help you make more sensible decisions and help defeat the stigma of a member of the herpesviridae family.
If You Have Zero Symptoms Getting Tested Won’t Help You
The problem is that blood tests for herpes when no lesions or symptoms are present are often bullshit. I realize that’s a pretty strong word, but after speaking with doctors who have administered these tests, it’s become more and more apparent to me how misunderstood and in some cases, just plain wrong the results they give are.
Part of the reason they’re flawed has to do with the fact that most people have been exposed to HSV-1 or oral herpes. “For HSV-1, close to 100 percent of people in the U.S. are antibody-positive because they have been exposed at some point in their lives, though only a percentage of these individuals will actually get cold sores,” says Adam Friedman, the residency program director at the George Washington University School of Medicine & Health Sciences in Washington, D.C. He adds that blood tests can be misleading because they usually don’t detect the herpes virus itself and instead look at the level of antibodies against the virus, which is merely a sign of immune response to it.

What Abnormal Results Mean
A positive test means you have been infected with HSV recently or at some point in the past.
Tests can be done to help determine if you have a recent infection.
About 70% of adults have been infected by HSV-1 and have antibodies against the virus. About 20% to 50% of adults will have antibodies against the HSV-2 virus, which causes genital herpes.
HSV stays in your system once you have been infected. It may be “asleep” , and cause no symptoms, or it may flare up and cause symptoms. This test cannot tell whether you are having a flare-up.
When Should I Talk With A Doctor
If you have a primary care doctor who you regularly visit, you can share your results with them to provide better insight into your next steps.
If you dont have a primary care doctor, you can consult with a physician or nurse from the testing site about treatment options.
If youve been treating your symptoms with medication and are still in pain or discomfort, reach out to a healthcare professional.

Are There Any Risks To The Test
There is no known risk to having a swab test.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
If you had a lumbar puncture, you may have pain or tenderness in your back where the needle was inserted. You may also get a headache after the procedure.
What Happens During An Hsv Test
HSV testing is usually done as a swab test, blood test, or lumbar puncture. The type of test you get will depend on your symptoms and health history.
- For a swab test, a health care provider will use a swab to collect fluid and cells from a herpes sore.
- For a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
- A lumbar puncture, also called a spinal tap, is only done if your provider thinks you may have an infection of the brain or spinal cord. During a spinal tap:
- You will lie on your side or sit on an exam table.
- A health care provider will clean your back and inject an anesthetic into your skin, so you won’t feel pain during the procedure. Your provider may put a numbing cream on your back before this injection.
- Once the area on your back is completely numb, your provider will insert a thin, hollow needle between two vertebrae in your lower spine. Vertebrae are the small backbones that make up your spine.
- Your provider will withdraw a small amount of cerebrospinal fluid for testing. This will take about five minutes.
- Your provider may ask you to lie on your back for an hour or two after the procedure. This may prevent you from getting a headache afterward.

Taking A Genital Or Oral Herpes Test
Testing for genital and oral herpes may be performed with a blood sample or a sample of fluid swabbed or scraped from a sore. Both types of samples are collected by a health professional when conducted at a doctors office, clinic, or community organization.
If you are experiencing an outbreak, a doctor can collect a sample for testing by swabbing or scraping a sore. Material from the sore can be used for a herpes viral culture, PCR testing, a Tzanck smear, or an antibody test.
If you are not currently experiencing an outbreak, a blood test may be used to identify HSV antibodies. If a doctor suspects a brain infection with HSV, a lumbar puncture may be performed to obtain a sample of cerebrospinal fluid for analysis.
How Does The Herpes Antibodies Test Work
A herpes antibodies test works by looking in your blood for HSV-1 antibodies or HSV-2 antibodies â typically the IgG type but sometimes the IgM type.
These tests only indicate exposure to either HSV-1 or HSV-2 at some point in your past. This does not necessarily mean that HSV is causing any current symptoms that you may have â since the exposure could have been years ago.
If you are worried about a new infection, it might be useful to take the test again around 21 days later to make sure that your body has had enough time to produce the antibodies.
The tests can give false-positive results. You may want to repeat the test or try other forms of testing to confirm the results.

Genital Herpes Is Common Shouldnt Cdc Recommend Testing For Everyone
CDC recommends herpes testing for people who have genital symptoms to confirm if they have it. Testing allows a healthcare provider to talk with patients about what to expect in the future. This includes talking about medications that help with symptoms. Providers can also tell patients how to lower the risk of transmitting herpes to sex partner.
CDC does not recommend herpes testing for people without symptoms in most situations. This is because of the limits of a herpes blood test and the possibility of a wrong test result. The chances of wrong test results are higher for people who are at low risk of infection.
Blood tests might be useful if:
- You have genital symptoms that could be related to herpes, or
- You have a sex partner with genital herpes, or
- Your provider found signs of herpes, but you still need a test to confirm it.
If you are sexually active, talk openly and honestly with your healthcare provider about what tests are right for you. These tips can help.

Youll have to check with your insurance network to see whether at-home STI tests are covered.

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.

This depends on the individual. People with herpes can experience outbreaks within 2 to 12 days of infection however, many people may not experience symptoms, depending on how their body reacts to the viral infection.
The HSV-1 virus goes through dormant phases before reactivating. Herpes can be spread even when asymptomatic, as cells that contain the virus are dropped from the skin during a process called shedding.
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.
