When Is It Ordered
HSV PCR testing or herpes culture may be ordered when you have signs and symptoms of a herpes infection, such as a blister or blisters on or around your eye, mouth, genitals or rectum.
Herpes PCR testing may be ordered when you have signs and symptoms of encephalitis that a healthcare practitioner suspects may be caused by a virus. Examples of these signs and symptoms include:
Prenatal and newborn testing
- A pregnant woman who has been diagnosed with herpes may be monitored regularly prior to delivery to detect a reactivation of her infection.
- A baby born to a mother who has active lesions during delivery may be tested before symptoms appear to assess whether the baby was exposed to HSV during delivery.
- A mother and newborn may be tested for HSV soon after delivery when a baby shows signs of HSV infection, such as meningitis or skin lesions that could be caused by the herpes virus.
HSV antibody testing may be done when your healthcare practitioner wants to determine if you have been exposed to HSV in the past.
Ways To Limit Exposure
There are sexually active couples out there who have managed for years to prevent the spread of the disease from one partner to the other. It takes care and attention to detail, but it is definitely possible.
First, try to avoid having sex when there are any blisters or sores present. Having sex during an outbreak is the easiest way to give someone herpes.
Beyond safe sex practices, for those with recognizable symptoms, not spreading the virus hinges on knowing when a flare-up is occurring even before any cold sores show up. Most often, that means looking out for a âtinglingâ sensation in and around the infected area. Sometimes, the skin has a mild burning feeling, and muscles nearby may feel like theyâre âasleep.â
For those without recognizable, symptoms, itâs a question of being tested. If youâre sexually active, and especially if you find out any past partner is infected, get tested for herpes, either by your doctor or at a clinic. For asymptomatic carriers, being aware of your condition and using a condom absolutely every time you have sex can dramatically reduce the chances of infecting someone else.

Testing by NAAT is appropriate when:
Cultures from lesions caused by HSV can yield positive results within 24 hours.
Sensitivity varies depending on the lesion being sampled Footnote 21. Sensitivity of culture declines when lesions start to heal and is low for recurrent lesionsFootnote 21. Due to its superior sensitivity, consider NAAT when a false negative culture result is suspectedFootnote 1Footnote 23. If NAAT is not available, viral culture can be repeated on fresh lesions.
Consult the local laboratory for the availability of HSV TSS.
A study of TSS showed a sensitivity of 80.5% and specificity of 98.5% for HSV-2, and a sensitivity of 91% and specificity of 96.4% for HSV-1Footnote 28.
TSS testing can demonstrate whether partners are serodifferent or serodiscordant or concordant .
TSS may be useful in the following situations:
TSS should not be used for screening asymptomatic people because:

What Percentage Of The Population Has Herpes
What percentage of the population has herpes? More than 3.7 billion people under the age of 50 about 67 percent of the global population are infected with herpes simplex virus type 1 , according to a new report from the World Health Organization.
- HSV-2 infection is more common in women than in men (almost 1 out of 9.
- HSV-2 infection is also more common in blacks than in whites
- Genital herpes is common in the United States. More than one out of every six people aged 14 to 49 years have genital herpes.
What Are The Symptoms And Signs Of Herpes
Oral and genital Herpes infections often have no symptoms or mild symptoms that can either go unnoticed or be mistaken for other types of bacterial or fungal infections, in both men and women. Occasionally, the virus may be present with no visible signs and can still be passed on, by a process called asymptomatic viral shedding.

What Affects The Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- If a culture sample is taken from a crusted, older sore.
- If a blood sample is taken before antibodies against HSV have formed. This period is called the window period or seroconversion period.
- If you are taking antiviral medicines, such as acyclovir, famciclovir, ganciclovir, or valacyclovir.
What You Need To Know About Herpes And How Its Transmitted
Two versions of the herpes simplex virus can cause this infection, according to the Centers for Disease Control and Prevention : herpes simplex virus type 1 and herpes simplex virus type 2 .
You might be thinking, Oooh, wait, HSV-1 causes oral herpes, and HSV-2 causes genital herpes, right? Technically, yes. But thats not the full picture. Both viruses can infect either your mouth or your genitals through skin-to-skin contact, the CDC explains.
HSV-1 has a predilection for the oral mucosa, but cases affecting the genitals are rising, Susan Bard, M.D., a New York City board-certified dermatologist and adjunct clinical instructor at the Mount Sinai Hospital, tells SELF. This can happen if, say, a person with HSV-1 in their mouth passes the infection to someones genitals while performing oral sex. And although HSV-2 is still behind most cases of genital herpes, it can cause oral herpes when someone with this infection on their genitals passes it to another persons mouth during oral sex.
You might think these signs would make it really obvious that something is up with your health if you have herpes. But its also entirely possible to have herpes without exhibiting any symptoms at all. The virus can lie dormant in the body without ever making itself known. Thats why so many people have herpes without realizing it, the CDC explains.

When Can A Blood Test Be Performed
Blood tests can be performed even when there are no symptoms present. If the herpes antibodies are found in the blood, it means that herpes simplex is latent in the body.
This method of testing has the advantage that it can be done even when a person has no symptoms, so it is a very effective way to detect an established herpes infection. Blood tests do not require swabbing a lesion, so they can be done long after symptoms have faded.
Type-specific blood tests are ideal for those who have had a history of genital symptoms but have never had a successful confirmatory test.
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.

When Should You Consider Getting Tested
Herpes is a sneaky, deceitful virus. It hides deep inside your nerve cells for unpredictable periods of time before triggering visible symptoms. In many cases, it infects the body and spreads to others without any obvious signs at all. As many as 90 percent of people infected with herpes are unaware they have the virus because theyve never experienced an outbreak.
People who dont have symptoms are more likely to transmit the herpes virus through a phenomenon known as asymptomatic shedding. This occurs when the virus sheds from the skin and spreads to others, even when no sores are present. Asymptomatic shedding is undetectable as there are no signs or symptoms, but it’s real.
According to research, at least 70% of infected people experience asymptomatic shedding of HSV-1 at least once a month. Many may even shed the herpes virus without symptoms more than six times per month.
Given that the herpes virus doesnt always trigger outbreaks and symptoms, testing is an important way to monitor your health. The CDC recommends testing if you are experiencing symptoms that could be related to herpes or if you recently had sex with a new partner who has genital herpes.
Remember, its possible that early herpes symptoms may not seem related to herpes. An initial herpes outbreak causes flu-like symptoms, including fatigue, fever and chills. These symptoms may be paired with pain, itching and redness around the affected area.

Useful Methods Include Testing An Actual Lesion
Keep in mind that theres no such thing as safe sex, only safer sex, which means using protection and being open and honest with your partner. It can definitely happen, Friedman says of the chances of transmitting the virus to a partner without a visible outbreak. Its called asymptotic shedding there are studies showing that the rates of transmission of HSV-2 are the same for symptomatic and asymptomatic. He adds that this is why using protection during sexual contact is so important, regardless of what blood tests say. 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.
Like Hutcherson, Friedman also doesnt recommend blood tests for herpes in the absence of symptoms. The tests that are useful involve sampling the actual blister or cold sore, he says, which can involve smearing scrapes of skin cells from the sore onto a slide, targeting the infected cells. As with some of the blood tests, though, this sampling test still wont tell you what type of herpes virus is present. A viral culture, on the other hand, will tell you which virus you have, though it takes some time to come back. Direct fluorescent antibody is by far the best, Friedman says, as you can get a result in a matter of hours which can be as useful as a culture. Not all hospitals have access to this method, however.
