Herpes I & II Test

Herpes Simplex Virus Type 1 & Type 2 IgG (HerpeSelect)

Tell me about this test.

Known as HerpeSelect, this blood test is a serologic type-specific gG-based assays. Recommended by the CDC, this test looks for antibodies that are specific to the Herpes I virus and the Herpes II. An accurate screening involves either a positive culture that has been typed (1 or 2), or a blood test that accurately distinguishes between types 1 and 2.

What kind of sample is required?

One quick blood draw is taken by a trained phlebotomist at the Test Center and you'll be on your way.

Any preparation?

None.

What do I have to know about the results?

This test looks for antibodies specific to Herpes I and Herpes II (HSV-1 &HSV-2). 70% of American adults have oral herpes or cold sores. If you test positive for HSV-1, it is most likely oral herpes. If you test positive for HSV-2, it is most likely genital herpes.

The tests provide a number result called an "index value." <0.9 indicates a negative result. 0.9 - 1.1 is "equivocal", which means that it's unclear and another test should be run later. This result is rare. An index value above 1.1 is considered positive. Any value between 1.1 and 3.5 can be a "low positive" and could be false. Another test may be indicated.
