It is very important for you to know since you can give herpes to someone else without knowing you have it. The blood test detects the levels of antibodies in the blood used to fight the herpes virus.
The antigen test is similar to the culture method, and also looks for the presence of the herpes virus in the lesion. Herpes viral culture of a lesion is a laboratory test to check if a skin sore is infected with the herpes simplex virus.
A normal (negative) result means that the herpes simplex virus did not grow in the laboratory dish and the skin sample used in the test did not contain any herpes virus. Be aware that a normal (negative) culture does not always mean that you do not have a herpes infection or have not had one in the past. An abnormal (positive) result may mean that you have an active infection with herpes simplex virus. The most common method to test for genital herpes is to swab a blister and have the sample analysed at a laboratory. Herpes simplex virus (HSV) types 1 and 2 cause genital herpes infections and are the most common cause of genital ulcer disease in industrialized nations. He took a swab and sent it to the lab and the results came back positive (it was not a type specific test. I made an appointment and when went in they had me do a urine test and a very painful culture swab, along with blood work.
False-positive results (testing positive when herpes infection is not actually present) can also occur, although more rarely than false-negative. From what you’ve told me here, it sounds like your herpes test was probably accurate.
Healthcare providers can also take a swab of an area that has symptoms and run DNA testsknown as Nucleic Acid Amplification Testing (NAAT).
You can test false positive, or false negative, over and over, whether or not you exhibit the classical signs of herpes. I wanted to share my experience where I tested positive for herpes through a culture, but turned out not to have herpes.
Cells or fluid from a fresh sore are collected with a cotton swab and placed in a culture cup.
The herpes viral culture of lesion test, also known as the herpes simplex virus culture, is a laboratory test that is used to determine if a skin sore contains the herpes simplex virus. Herpes test – taking a swab test from a genital sore is the only way to accurately diagnose genital herpes. He took a swab and sent it to the lab and the results came back positive (it was not a type specific test) I later had type-specific blood tests for HSV-1 and HSV-2, four weeks after the date of my last, possible exposure, but these came back negative. Blood tests are available for people who may not have had symptoms or if the signs have already healed. But the last 2 outbreaks I’ve had have come back Positive for HSV-2 when swabbed and Negative for HSV-2 when blood is drawn (tests taken at the same time).
Hi all, a year after initial symptoms I had a swab test type specific come back positive for type 2. Genital herpes can be challenging to diagnose, but an accurate diagnosis is the cornerstone for everything that follows and is absolutely essential.
She did a swab test for herpes anyway, just to be sure, in which she just rubbed the end of a q-tip over the bumps I had which never blistered at any point. Your healthcare provider will look at the sores and see if they seem typical of a herpes outbreak.
Hello everyone, I was recently diagnosed with HSV-1 genitally in early July with a positive swab test result. The doctor said it was probably herpes, so I took herpes drugs before the results came back. Psychological Stress As A Trigger For Herpes Zoster: Might The Conventional Wisdom Be Wrong? Children, with an undeveloped immune system, can be exposed to Herpes 1 with a simple kiss from a loved one, then they can have herpes forever! We suggest ordering 2, 1 for yourself and 1 for your partner, and have them on hand when you have an outbreak.
Most of these tests can't distinguish between a current infection or a recurrent herpes infection.
One of the problems may be a false positive for HSV2 for persons with an oral HSV1 infection.
Rather than growing the virus as in the culture test, this test identifies the herpes by the presence of antigens. Using a scraping to look for Tzanck cells, it is sometimes called the Chickenpox skin test. Herpes infections include herpes genitalis, which is genital herpes, or cold sores on the lips or in the mouth. If the culture is positive for herpes, you may have recently become infected. Often, the infection is diagnosed based on the symptoms and the appearance of the blisters. Before any results came back my doc had too me that given my symptoms and what he saw, it looked like herpes.
From her physical examination and the negative blood test she said she thought I didn’t have herpes but a yeast infection.
Yes I did have a swab test and it was positive for herpes and no it was not typed with the swab. Thus, a person without herpes can sometimes test positive with the blood tests, and people with herpes can test negative.
Herpes tests can be wrong, but it is much more common for them to give a false negative (because we are swabbing a herpes sore that is already healing up) , than for the test to give a false positive. With all three techniques, a carefully gathered medical and sexual history adds to accuracy. For patients with lesions in the throat or eye, a sterile swab must be used for sample collection. But 100 of the labs using gG-based tests accurately reported that the blood sample was negative for HSV-2. If direct HSV tests are repeatedly negative and the symptoms are recurring, the patient should be advised to have type-specific herpes serology.
While the herpes viral culture of lesion test can be performed on patients with active infections, the most accurate results will be obtained when the patient is first experiencing an outbreak.
The lesions that they did swab (not the initial one that scabbed, but the other two smaller ones) were open and wet.
I am having a hard time believing that this diagnosis is correct and was wondering about the false positive rates of such a test. It’s also possible for an infected mother to transmit herpes to her baby, potentially causing blindness, brain damage even death. The highest incidence of initial infection occurs between six months and three years of age.

The results then go to Private Diagnostics and they send the results to you in a secure manner with a password that only you and Private Diagnostics know. PCR techniques make many copies of the viral genetic material either DNA or RNA in a short time (4 hours) so that even tiny amounts of virus are senough for a positive test.
An antigen is a substance that causes your immune system to produce antibodies against it, in this case, the herpes virus. The culture often fails to find the virus even when it is present (false-negative results).
When I went back about a week later for follow-up, he told me My culture was positive for herpes virus, but my blood test was negative. The lab values are as follows: In January 2014 my IgM test came back positive but my IgG was 0.
Your swab test was either negative as a result of a false negative (meaning you DO have herpes, but the test was wrong) , or because the lesion was caused by something else entirely. For example, I didn’t test positive for HSV-1, so cross-reactivity with HSV-1 was out as a reason for my potential false positive. It is a very good test, but there are issues with false positive results with one form called the HerpesSelect ELISA.
Another method is polymerase chain reaction (PCR) -based qualitative test for HSV1 and HSV2 detection and typing of vaginal lesion swab specimens from symptomatic female patients. If a person does experience signs of infection, we recommend obtaining a culture test (a swab from the symptom) within the first 48 hours after a lesion appears. An outbreak that looks like herpes, but that comes back with a negative test for virus, may still be a herpes infection. Chlamydia and gonorrhea screening is done either through a urine test or through a swab inside the penis in men or from the cervix in women. This test is most likely accurate when a person is newly infected, that is, during the first outbreak. Again, I did get a positive for HSV-1, but I would like to know how accurate the negative result for HSV-2 would have been for this test? I was diagnosed positive in 2009 through a swab and 3 weeks ago swab was taken again and it came back negative, I am so confused, Cld this be something else? If a person has been recently infected they might not get a positve antibody test, because the antibodies haven't developed yet.
It is then watched to see if the herpes simplex virus (HSV) or substances related to the virus grow.
A sample of fluid is collected via swab from an open sore and inoculated into cells that allow the virus to grow. I pointed out another sore spot on my rectum to the doctor which he said was herpes, and suggested I have it tested. Primary Herpes simplex virus (HSV) infection in children is usually asymptomatic or non- specific. Beyond 48 hours of the symptoms appearing, there is a risk of receiving a false negative test result. If such changes occur, the test is declared positive, meaning that the herpes virus is present in the sample. Basically, if you test positive for herpes type 1 and negative for 2 that does not mean you don’t have genital herpes.
Other considerations include the cost of false positives or false negatives, which may be difficult to quantify, the value of superior service to clinician clients, and the laboratory’s reputation for quality and service. It sounds like in your case you did have an active sore when you got tested, and the swab found HSV-1 in the sore. A blood test also may help detect a herpes infection, but results aren’t always conclusive. She gave me medication for the yeast infection which seems to have cleared up all of my symptoms. He told me that the blood test was accurate and type-specific, and if I had herpes, the antibodies would have formed by the time I was tested.
Your doctor will examine your condition and should take a swab and sample of the infected tissue or a blood test. My doctor didn’t have to break a blister on me to do a swab test, and it came back positive for HSV-2.
All negative cultures should be followed up with an accurate blood test three to four months from possible exposure to see if the person really has herpes. 01 over the cutoff is basically negative) , then the lesion that was positive followed by a strongly positive HSV 1 antibody test suggests seroconversion during that time period. Antibody tests are sometimes done but are not as accurate as a viral culture at finding the cause of a specific sore or ulcer. My swab test for the herpes revealed a positive for HSV-1, and a negative for HSV-2 (so I assumed I must have acquired the virus from oral, or something like that). Most experts agree that when possible, amplified molecular testing is preferable to culture for diagnosis and to guide management decisions for people with possible genital herpes. One study found that herpes cultures give FALSE NEGATIVE results 76 of the time when compared to the more accurate PCR test described below. The most important fact to know in terms of Herpes testing is that blood testing with an IgG test is the BEST test for diagnosing the disease.
For this reason, anyone seeking an accurate diagnosis of genital herpes must be sure to get a type-specific serologic test, which can accurately distinguish HSV-2 from HSV-1 antibodies.
Know that having an accurate sexual history as well as a description of your symptoms is very important as your health care provider evaluates you. If you test positive, but your risk for getting the virus is low, you may need to be tested again.
It can be done on cells or fluid from a sore or on blood or on other fluid such as the person's spinal fluid. I have a very tiny area that is slightly irritated and I had a swab done and it came back positive for herpes, they did a blood test as well and it came back negative, they waited 3 or 4 months and did another blood test and still negative. It is, however, four times more sensitive than a culture and should be used whenever possible for diagnosing herpes from a swab sample.
The PCR swab test is obtained just like the viral culture, then using specialized laboratory techniques; the sample is amplified many times.
Most (90 in one study) of these people have positive blood tests for HSV with no history of symptoms or outbreaks.
The initial dr then took a swab test where he wetted the sore and then rubbed a q tip on the blood that had come from the sore after rubbing it.
There are several tests that are used to diagnose herpes, some are more accurate than others. There is a new test, dubbed the silver pap that includes a herpes PCR swab test in addition to the GC (gonorrhea and Chlamydia) tests that are performed at this time.
However, I have been reading lately that false positives for herpes can be rather high or common in some cases.

I was given Cipro for UTI, Flagyl for BV, Diflucan for the Yeast and Valtrex (500mg 2x day) for possible HSV. A blood test to test for herpes antibodies can sometimes be helpful, for example if you have a partner and are unsure if they are at risk of catching herpes from you, or if your doctor strongly suspects you have herpes but your swabs are repeatedly negative. Swab tests include viral cultures, Polymerase Chain Reaction (PCR) swabs, Tzanck smears and Pap smear. Cells or fluid from a blister or sore are collected with a cotton swab and placed in a culture medium. I was just wondering if this is possible, especially considering the doctors were certain it wasn’t herpes. The swab should then be removed from the transport medium and firmly rolled against the inside of the tube to express as much fluid as possible. When there’s a genital herpes outbreak, a doctor can take a swab from the sores to test for herpes virus, but the swab should be taken within 48 hours of the outbreak.
Cells or fluid from a fresh sore are collected with a cotton swab and placed in a culture Click here to see more information. In addition to the Western Blot, there are now two type-specific serologic tests that can accurately detect Herpes and distinguish between HSV 1 and 2. Blood tests for herpes do have a place in specific clinical situations, but that’s for another post. Although PCR can detect HSV DNA from later stages of lesions than virus culture, there is a theoretical risk of false-positive results occurring due to sample contamination before amplification. She then said that she has NEVER had a genital herpes outbreak but may be a silent carrier.
HSV-1 generally infects the face or lips (eg, cold sores) and up to 80 of Australian adults carry this type. However, if your HerpeSelect test is indeterminate (not definitely positive or negative) or weakly positive, it may be worth it to you to send a blood sample to the University. He swabbed the sores and looked at it under the microscope, and he came back and said the virus didn’t look like herpes under the microscope, either. Since I live an hour away from my gynecologist and was just looking for the most convenient way to get tested, I found a website that could send a lab order for the STD tests to my local walk-in lab, where I could get my blood drawn without having to make an appointment. DNA testing is usually done only if the culture is negative but the practitioner still suspects herpes, or if the patient has received treatment for herpes.
If a person has a genital herpes blister or ulcer a swab test can be performed on collected cells or fluid. Could what I have be herpes, even though it doesn’t really look or act like herpes, and three tests have come back negative? As Johnston pointed out, while most herpes tests in general are considered 95 percent accurate, if you’re low risk, that rate drops. If you score above 1 and you get a positive swab you’re considered positively positive. Herpes blood tests are not entirely reliable, and it’s possible for a person to have herpes (either 1 or 2) , but not to test positive.
Quest Diagnostics offers a PCR-based test that provides type-specific direct detection of HSV from vaginal swabs (SureSwab; test code 90570) or ThinPrep endocervical liquid Pap specimens (test code 90569).
The blood test is not as accurate as the viral culture test to diagnosis a specific lesion, because it only tests whether a person has been exposed to the herpes virus. Depends on timing: False negatives can occur, especially if the ulcer is cultured too late, after healing has already begun. 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.
No good screening test exists for herpes, a viral infection that can be transmitted even when a person doesn’t have symptoms.
False negatives can occur if there is not enough active virus in the test sample, which can occur if the lesion is cultured more than 48 hours after the symptoms appear. A few days ago, I went to Planned Parenthood for what was diagnosed as a first outbreak of genital herpes- though we’re still waiting on results for the swab test. The doctor took one look and said it was definitely herpes, sent a swab test off to the lab, and gave me prescriptions for Valtrex and some ointment. Diagnosis of HSV is made by a viral swab test called PCR, sampled by swabbing a new blister.
There are three main laboratory methods to diagnose the virus: culture, PCR, and blood tests for antibodies, although false negative results are possible.
Just to make double-sure, I got a blood test a few months later after my regular check-up, which also was negative for herpes. In addition, IgM tests cannot accurately distinguish between HSV-1 and HSV-2 antibodies, and thus very easily provide a false positive result for HSV-2. The sooner you come in for the test after you get a new blister the more accurate it will be. I had a vaginal exam and the doctor took swabs and then put me on and antibiotic and valtex.
Other viral STIs, such as herpes and genital warts, are often diagnosed by visual identification of a lesion.
However, results depend on multiple factors, including the adequacy of the specimen, and a negative result may not exclude infection. The most accurate test involves a tissue culture, in which a swab is rubbed over the lesion within 48 hours of the lesion appearing. Is it possible to not have h after having unprotected sex with your partner who tested positive from a viral culture? Everything that my partner and I spoke about makes no sense that her test came up positive. It would be good to request a swab test of a lesion but instead of culture, you should request a PCR test, far more sensitive. Your doctor tests you for syphilis by taking either a blood sample or a swab from any genital sores you might have. Does Advil have any effect on the results of HSV tests, specifically on the results of the ELISA test? Possible exceptions may be those infected simultaneously at more than one site or those with very recent HSV-1 infection who have not yet seroconverted. 6) As I mentioned in my previous post, my last blood test for herpes came back negative for both HSV 1 and 2 at 0. Because false negatives and false positives occur, the results have to be weighed together with the clinical presentation and patient’s history.
