Herpes Tests

Results

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. Results from an antibody blood test are ready in 2 days. The results from an antibody test called an enzyme-linked immunosorbent assay (ELISA, EIA) may be ready in about 2 hours.

Herpes tests

Normal:	Normal results are called negative.
	No HSV grows in the viral culture.
	No viral antigens or DNA are found.
	No herpes antibodies are present in the blood.
Abnormal:	Abnormal results that show HSV are called positive.
	HSV grows in the viral culture.
	HSV antigens or DNA are found.
	Antibodies to the herpes virus are present in the blood.

Samples taken from newly formed sores containing fluid (blisters) are generally better than samples collected from older, crusted sores.

A normal (negative) test result does not mean you do not have a herpes infection. If the first test is negative but you have symptoms of herpes, more tests may be done.
