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.

Herpes Blood Test And Results
- The test is used for diagnosing both HSV-1 and HSV-2, which is performed for people who have the symptoms or close contact with an infected person.
- These tests are type-specific glycoprotein G-based that are used to detect any antibodies presence to the herpes virus in the blood.
- If the blood test shows the antibodies of HSV-2, you can confirm that you are infected by genital herpes.
- The commonly affecting is HSV-1, which is an oral infection, but still, there are chances for people with HSV-1 getting a genital infection and, in some cases, the type of herpes cannot be determined.
- The disease symptoms may tend to develop 2 to 20 days after getting exposed to the virus, so if you check as soon as the exposure, it may show negative but turns positive within days.
False test results
Usually, the herpes blood tests give the person accurate results, but it may go wrong when everyone should know. There are concerns regarding the faulty positive effects of the herpes blood tests.
This can happen with any of the diagnostic tests, but as this is a lifelong infection, it badly affects the person, which worries the researchers in the field. Considering these factors, this test is advised only to people with herpes symptoms or to the high risk persons of infection, like the partner of a patient with genital herpes.
Can I Take The Test At Home
At-home tests are available to test for evidence of an HSV infection. At-home herpes testing typically detects HSV antibodies in a self-collected sample of blood and may require additional follow-up if preliminary results are positive. At-home herpes tests can be obtained online or at a local pharmacy.

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 offices, clinic, or community organization.
If a patient is 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 a patient is 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.

In The Absence Of Answers
Herpes tests arent the only ones with a risk of false positive results. False positives can occur for any test that diagnoses viral infection based on antibodies, i.e., your bodys immune reaction, rather than direct detection of the virus. For similar diagnostics like HIV and hepatitis C testing, protocols automatically call for a second test that directly detects the virus whenever an antibody test comes back positive, said Paul Swenson, laboratory director in the department of public health of King County, Washington. Herpes, however, is a particularly challenging infection to directly test for, because the virus spends most of its time hiding in nerves. Swab tests can sometimes detect the virus during outbreaks, but this isnt an option for people without symptoms. Thus even the Western blot relies on antibodies, and may give indeterminate results to a small number of people.
But two steps of antibody testing are still more reliable than one step todays diagnostics for Lyme disease and syphilis are a two-step antibody testing approach, said Dr. Edward Hook, a medical epidemiologist specializing in STI screening and prevention at the University of Alabama, Birmingham, who questioned why such a standardized two-step approach hasnt taken firm hold for herpes.

Who Decides Which Diseases Are Notifiable And Why
The Council of State and Territorial Epidemiologists works with CDC to determine if a particular disease should be nationally notifiable. To make this decision, they follow a number of public health principles, for example, whether or not it is treatable whether or not it is preventable how common it is whether or not a public health response is needed whether or not there is a good source of information on the number of cases and whether or not it represents a significant public health threat . Information on HSV-1 and HSV-2 infections already exists in NHANES, so herpes infections have not been classified as notifiable diseases.

Which Herpes Test Should You Get
Each method of testing for herpes has advantages and disadvantages, from time and cost, to an increased possibility of false results. Often, people concerned about the virus use a range of herpes testing to get a more accurate, proven picture of whether or not theyre infected with HSV-1 or HSV-2.
Since herpes is a lifelong infection that cant be cured, its important to discuss testing options with your healthcare provider and make sure you receive an accurate result. Your healthcare provider will be able to tell you more about the best options for herpes testing based on your symptoms and situation.
Typically, your healthcare provider will carry out a physical exam before choosing the best testing method for you. As herpes symptoms tend to be worst during the initial outbreak of the virus, its best to talk to your healthcare provider as soon as you start experiencing symptoms.
In the event that you do have herpes, theres no need to panic. Both oral and genital herpes are extremely common, and a variety of effective treatments are available for both.
Our Valacyclovir 101 guide goes into more detail about one of the most common, effective drugs for treating both symptomatic and asymptomatic herpes. You can also learn more about the risk of catching herpes in our guide to how herpes is transmitted between people.

Quick Answers For Clinicians
Virologic and serologic testing methods are available to confirm herpes simplex virus infection. Direct detection of the virus by polymerase chain reaction or viral culture is recommended for neonates and patients who have an active infection with lesions, to test for disseminated bloodborne infection in immunocompromised patients, and for cerebrospinal fluid testing. Serologic testing for immunoglobulin G can be used to determine if a person has ever been exposed to HSV but cannot determine exactly when the exposure occurred or the site of infection. Type-specific serologic testing for HSV-1- and HSV-2-specific glycoproteins can determine the subtype of the virus, which provides useful information about prognosis and informs treatment and counseling.
Genital herpes is most often caused by herpes simplex virus type 2 , but HSV-1-associated cases are increasing. Recurrence and subclinical viral shedding occur more frequently in cases caused by HSV-2 than in cases caused by HSV-1, which may impact treatment and counseling decisions. Therefore, subtyping HSV using polymerase chain reaction or serology testing can guide treatment decisions and patient counseling. Subtyping may also provide epidemiologic information about transmission of the virus.

Doctors Dont Advise Getting A Blood Test For Herpes Without Any Symptoms
Hilda Hutcherson, assistant professor of obstetrics and gynecology at Columbia University Medical Center in New York, is one of those doctors. I usually dont do tests for herpes someone has a lesion or a sore, something I can see, I will do a swab and take it to a culture or check the DNA on the materials I removed, she says. If theres nothing there and I do a blood test and the blood test comes back positive, lets say its positive for type 1, what does that really mean? Most people are positive for type 1. She adds that someone could be HSV-1-positive and either have or not have genital herpes. The result doesnt mean much, and it makes people go crazy.
Hutchersons motto is pretty simple: Why stress yourself over something if you havent seen anything especially when its something as common as herpes? Lets say they have a blood test come in positive but theyve never had a lesion. Now what? You may never get a lesion, she says. Its for this reason that she recommends people do not get tested for herpes unless they have a visible lesion that can be cultured and sent to a lab. Lets say you get tested anyway and it comes back positive, despite the fact that you have no symptoms. What do you do?

How Often Are Herpes Tests Wrong
Meanwhile, the CDC and the US Preventive Services Task Force concur that the most widely available herpes test, called HerpeSelect, should not be used to screen asymptomatic people because of its high risk of false positives: Up to 1 in 2 positive tests could be false, according to the USPSTF’s most recent guidelines.
Gonorrhea May Become Resistant To All Antibiotics Sooner Than Anticipated
Some research has shown that two-step testing might improve the specificity that is avoid false positive results for the blood test which would be a great thing because these diagnoses create great anxiety and concern for people, he said. In a commentary accompanying the USPSTF guidelines, Hook expressed disappointment that herpes testing had barely improved over the past decade.
There is no perfect test but there are ways to reduce the inaccuracies and reduce the number of equivocal results and those are actively used in other diseases, he said in an interview with STAT. But they havent been used very aggressively for the purpose of herpes.
In the absence of sure-fire test advances, education and a lessening stigma surrounding herpes might help, not only by reducing test-related confusion, but potentially by bringing discussion of the virus out into the mainstream, said Hook.
Theres no major herpes advocacy group, he said. People call attention to diseases that they suffer from, but people with herpes dont feel they can call attention to it. And that creates a lot of suffering.

The Western Blot Test for Genital Herpes
This test is considered to be one of the most effective ways of diagnosing genital herpes, and it is thought that the test has great accuracy results. However, cost, time and availability are a major issue and this may make people turn to other types of herpes screening programs. Never the less, many physicians are willing to refer patients for a Western Blot test if they suspect an outbreak of genital herpes.
The HerpeSelect Test
This test comprises of two parts. Patients undergo the herpes immunoblot test and the genital herpes Elisa IgG test. The blood samples are analyzed at a laboratory, hence, the patient may have to wait for the test results. Both tests offer highly accurate results and as a rule, they will detect both variations of the herpes simplex virus . Recent studies show that herpes false positive results are unlikely when this type of test is used.

Genital Herpes is a nasty virus that comes in two different types, HSV-1 and HSV-2. They both have the same plan of attack: As many as 4-5 times each year, they attack healthy cells on your skin, hacking into them and forcing them to create clones of the Herpes virus tens of thousands of them. The cells are forced to work so hard that they eventually die, and when enough of them die, it leads to sores or lesions on the surface of your skin.
These sores are hard to identify as herpes just by looking at them. Theyre often mistaken for pimples, bug bites, or a rash. Anyone else that touches these lesions has a chance of contracting Herpes. Since they often appear on your thighs or buttocks, simply using a condom wont eliminate the risk. You dont even have to have visible symptoms to transmit Herpes to someone else.
