What Is The Most Accurate Test For Herpes

How Often Is A Positive Herpes Test Correct

Then although almost all negative tests would still be accurate, positive tests would only be correct 55% to 85% of the time. In other words, there would be a lot of false positive tests. The possibility of false positive tests in populations where herpes isnt common is a big concern.

1. Doctor diagnosed me for having HSV-1 because I was having an outbreak and prescribed me with Valtrex that worked but blood, urine, and swabs came out NEGATIVE for HSV-1& 2. Also boyfriend got tested 2x still negative. How is this possible?

How Do You Get Checked For Herpes

There are three ways that you can get checked for herpes:

Blood Test for HSV Antibodies

Blood testing for HSV 1 & 2 antibodies is the most common method of testing for herpes infection. This is because it can detect if youre infected with herpes, even if youre asymptomatic.

Viral Culture

A viral culture can be performed with a urine sample or a swab of the suspected infected area. The sample will be used to see if the virus grows in a lab culture. It is a good choice to confirm you have the virus if youre experiencing symptoms, but it is only effective if the virus is active in a sore or lesion.

PCR Herpes Testing

PCR testing looks for HSV DNA from a blood sample or from a lip or genital sore. It can determine the difference between HSV-1 and HSV-2. PCR testing is expensive, but it is fast and efficient.

How Soon Can You Test For Herpes

I know that you may be anxious to get tested following unprotected sex, or the development of symptoms, but it is advised that you wait 6-12 weeks after sexual contact before taking an at-home herpes blood test. This allows enough time for the antibodies of HSV-1 and/or HSV-2 to develop.

If you are sexually active you should get tested for herpes regularly. LetsGetChecked offers a 30% saving on each herpes finger prick test if you subscribe for tests every three months.

If you are currently experiencing the symptoms associated with herpes, you can get tested via a urine or swab test right away to determine if you are infected with the STD. However, this will only prove effective if you are in the active stage of the infection.

How Much Does The Test Cost

The cost of testing for genital and oral herpes depends on the type of test that is performed, where the test is conducted, and whether the patient has medical insurance. Testing is often covered by insurance when ordered by a doctor, although patients may still be responsible for costs such as copays and deductibles.

Is A Blood Test For Genital Herpes Included When I Ask To Be Tested For Everything Why Does Cdc Recommend Testing For Other Stds But Not Herpes

Herpes blood tests may or may not be included. Your doctor chooses STD tests based on your sexual behaviors , as well as how common the infection is in the area that you live in. This is why you should have an open and honest discussion with your doctor about your sex practices and history. When you go in for STD testing, it is important to ask your doctor which infections you are and are not being tested for, and why.

STD tests are usually done for infections that have serious outcomes if they are not treated. For example, finding and treating curable STDs like chlamydia can stop them from causing serious complications like infertility in women. Genital herpes does not usually result in serious outcomes in healthy, non-pregnant adults. More often, the stigma and shame from a genital herpes infection can be more troubling to someone who is infected than the disease itself. If you are worried about genital herpes, you should talk with your doctor about whether you should be tested.

Should I Get Routinely Tested For Herpes

The CDC doesnt recommend routine testing for herpes. Individuals who are diagnosed with genital herpes but who do not have symptoms typically dont change their sexual behavior. Therefore, routine testing has not been effective at preventing the spread of the virus. It is also possible to get a false positive result from a herpes test, which is another reason the CDC doesnt encourage routine use of the test.

Syphilis And Gonorrhea Rates Have Risen Sharply In Us Cdc Says

When tests fall between 1.1 and 3.5, more testing is necessary, said Johnston. This recommendation is also noted in the 2015 CDC Sexually Transmitted Diseases Treatment Guidelines. But some patients will never be referred for a second test.

I think most clinicians are unaware and perhaps labs dont have this available and/or it is not straightforward to order, Johnston said of second-step tests.

But while her facilitys Western blot is considered highly accurate, it is expensive and cumbersome to perform. Each test costs over $200 and the University of Washington is the only lab that provides it.

Other confirmatory tests also exist, for instance Biokits HSV-2 Rapid Test and Quests own HSV-2 IgG Inhibition assay. The latter, which adds only $4 to the price of the HerpeSelect test, performed well in a study conducted over a decade ago. Rick Pesano, the medical director for infectious disease at Quest, believes that with more awareness, the test could stand in for the Western blot. But the test was not mentioned in the USPSTF guidelines because it still has not been evaluated in asymptomatic individuals, according to Cindy Feltner, associate director of the RTI-UNC Evidence-based Practice Center, who helped prepare the science review for USPSTF.

We need better diagnostic testing. That is where we are stuck at this point, said Johnston. We dont have a good test thats inexpensive, high throughput, and reliable.

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.

The Accuracy Of Various Herpes Tests

This table summarizes the overall accuracy of different herpes tests. Please especially pay attention to the most common test, the IgG testâand most importantly to its false positive and false negative rates.

The table has three columns:

• Test accuracy: how accurate is the test in detecting the herpes virus
• False positive: the test detects the presence of herpes, but the person doesnât actually have it
• False negative: the test doesnât detect the presence of herpes, but the person does have it

Please note: the numbers in the table are averages and may vary from case to case based on factors such as when the test is performed , the testing technique, and the herpes viral load.

* The Washington University test is considered the âgold standardâ blood test. The false-negative and false-positive rates for the commercially available IgG test are based on a comparison to the Western blot results of the Washington University test.

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 Can People Test For Herpes

A person can ask for a herpes test at any sexual health clinic or a doctors office. A healthcare professional will either swab a blister or draw a blood sample.

At-home herpes tests often require a blood sample through a finger prick.

Once a person receives their test results, they should contact a doctor to discuss treatment options, if necessary.

How Accurate Are Blood Tests For Herpes

According to the University of Maryland Medical Center, nearly every person in the United States about 85% of the population will be infected with herpes by the time they reach their sixties. If youve ever had one of those annoying cold sores on your tongue, youve already experienced an HSV outbreak. For most people, the herpes simplex virus will never present any lasting or major symptoms but for people who become infected with genital herpes, a common STI which causes painful sores and flu-like symptoms, the virus is a serious medical issue which needs to be managed with antiviral medication. Of course, in order for herpes to be managed effectively, it needs to be diagnosed first but just how accurate are our current testing methods? In this article, our Baltimore clinical malpractice attorneys will explain how herpes is diagnosed, which tests are most accurate, and what to do if you or your partner was the victim of a herpes misdiagnosis.

What Do The Results Mean

Your HSV test results will be given as negative, also called normal, or positive, also called abnormal.

Negative/Normal. The herpes virus was not found. You may still have an HSV infection if your results were normal. It may mean the sample didn’t have enough of the virus to be detected. If you still have symptoms of herpes, you may need to get tested again.

Positive/Abnormal. HSV was found in your sample. It may mean you have an active infection , or were infected in the past .

If you tested positive for HSV, talk to your health care provider. While there is no cure for herpes, it hardly ever causes serious health problems. Some people may only have one outbreak of sores their whole lives, while others break out more often. If you want to reduce the severity and number of your outbreaks, your provider may prescribe a medicine that can help.

Signs And Symptoms Of Herpes

Oral herpes is an infection in the mouth, caused by HSV-1 . Symptoms often include cold sores or fever blisters, but you can have oral herpes without any symptoms.

The herpes simplex virus can be dormant until an active outbreak occurs. The initial infection typically has the worst symptoms, ranging from flu-like symptoms and swollen lymph nodes to headaches. Sores may occur in and around the lips and mouth. Recurring infections are usually milder, and may include redness, itching, or swelling. Painful, fluid-filled blisters can occur and are highly contagious. These blisters often turn into sores , which will then scab over and typically heal in a few days.

Symptoms of genital herpes range from none to more severe manifestations . The majority of genital HSV infections are mild, with little to no symptoms following the initial outbreak. For people who do experience symptoms, the usual course begins with genital inflammation, where the skin may itch or burn. Blister-like sores may appear. The sores may open, scab over, and heal.

Other indirect symptoms that can occur during an active herpes virus infection include fever, headaches, muscle aches, and a burning sensation during urination.

If you think you may have a herpes infection, home testing could be a convenient option for you. If youâre wondering how to get tested for herpes at home, thereâs good news: testing for HSV-2 is easy with the Everlywell female STD Test or male STD Test.

Finding Out The Hard Way

No good data exist on how often patients with questionable positive results are actually re-tested. Until the 2015 update, CDC herpes testing guidelines had no mention of confirmatory testing for low-positive results, said Johnston. So patients often discovered the option not through their doctors, but through searching the web and reading online herpes forums.

That was the experience of Bryan, a 40-year-old man who lives in Indiana, who wrongly believed he had herpes for about two months in 2011. The misunderstanding actually put him at higher risk, he said: During those months he considered joining the hundreds of thousands of Americans on dating sites for herpes-positive people. Exclusively dating people with herpes would have increased his likelihood of contracting the virus.

The experience of YT, a 33-year-old mom who has suffered from frequent herpes symptoms over the last year, shows another side of the testing breakdown. She believes she was given HSV by a partner who didnt realize herpes wasnt included in his previous STD tests, she told STAT. Having herpes has caused her significant emotional trauma, and has driven her to permanently swear off dating. Had her partner known his true status, she wonders if her story would have been different.

People call and say, I just dont know whats going on, he said. Weve almost become de facto counselors.
