What is HSV DNA test?

HSV testing identifies the presence of the virus in a sample from a blister, sore or fluid to diagnose an active herpes infection or testing detects antibodies in the blood to determine previous exposure to herpes.

How is HSV PCR test done?

Polymerase Chain Reaction (PCR) 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.

What does HSV by PCR mean?

Special Instructions. HSV PCR is a single test that both detects the presence of HSV DNA and determines which type is present in the positive samples. There is no mechanism, therefore, for testing for HSV-1 without simultaneously testing for HSV-2.

What is HSV type 2 DNA?

The herpes simplex virus 1 and 2 DNA PCR is a test that can detect an active infection of type-1 and type-2, as well as differentiate between them. PCR stands for polymerase chain reaction.

Can HSV antibodies go away?

It may take between six and eight weeks to detect antibodies in a herpes blood test after first becoming infected with HSV. Also, antibodies may disappear with time, especially if the person has infrequent recurrences of herpes.

How long does a HSV PCR test take?

Herpes tests are done to find the herpes simplex virus (HSV). Results for a rapid viral culture may take 2 to 3 days, while results for a standard culture can take up to 14 days. Antigen detection test results are ready in a day. Polymerase chain reaction (PCR) test results are ready in 1 to 3 days.

Is HSV PCR accurate?

PCR test: The PCR test can tell if you have genital herpes even if you don’t have symptoms. The PCR test looks for pieces of the virus’s DNA in a sample taken from cells or fluids from a genital sore or the urinary tract. This is a commonly used test to diagnose genital herpes and is very accurate.

How accurate is HSV PCR blood test?

HSV-1: At least 94% of positive tests give the correct result, and at least 99% of negative test will be correct. HSV-2: At least 98% of positive tests are correct, and at least 97% of negative tests are correct.

Which is the most sensitive method to detect HSV?

Studies have shown the HSV PCR sensitivity to be from 75% to 100% with a specificity of 100%. In conclusion, the detection of HSV DNA by PCR has been proven to be the most specific, rapid, and sensitive means to diagnose anogenital and CNS infections.
