HOTLINE: Herpes 1 and 2: What’s the Difference?

Wednesday, January 13th, 2010

We get this question a lot.  If you have HSV-1, does that mean you’re going to get genital outbreaks?  And what does it mean if you get a positive test result for Herpes 1 (HSV-1) and a negative result for HSV-2?  Okay…let’s break it down.  HSV-1 is super common and is often associated with cold sores.  More than half the adults in America have HSV-1.  HSV-2, also common, is most frequently associated with rashes down below.  But…and here’s the tricky part.  HSV-1 can cause genital symptoms but it’s less likely to cause frequent, recurrent outbreaks.  The HerpeSelect test that we offer is a type-specific test. That means you can know which HSV type you may be dealing with.

A note about your negative test result for HSV-2.  HerpeSelect detects antibodies to HSV so if you just had an unsafe exposure yesterday, the antibodies will not have formed.  Practice safe sex and get tested again in 3 months to confirm your negative result.

HOTLINE: When is the right time to test?

Monday, November 30th, 2009

This may be the #1 question we hear.  The short answer?  If you are sexually active and have not been tested for HIV or other STDs in the past 12 months, the right time to get tested is right now.  It’s possible that you may have an STD and simply do not know it.  That’s why the CDC and other organizations want everyone who has sex to get a yearly STD test as part of their normal health routine.

Now, if you want to try to “time” an STD test based on what you think was a recent unsafe experience, there is a more nuanced answer.  Let’s say that up until yesterday you were a virgin and never had any sexual contact — vaginal, anal, oral or other.  And yesterday you got busy in an unsafe way with someone who told you, after having a robust night of lovemaking, “Wow, that was great, but I should tell you that I have genital herpes.”  Or HIV or Hepatitis C or another STD.  In that instance, you need to get yourself checked out and think about the timing of the test.

Viral infections like Herpes (HSV-2) and HIV may not develop detectable antibodies to the virus for up to 3 months.  This is called “seroconversion.” The HIV DNA by PCR test will look for DNA cells as early as 28 days after a possible exposure because it’s not looking for antibodies.

This is getting technical but diagnostic screening is simple.  Haven’t been tested in 12 months and you’ve had unsafe sex?  Get tested today and then wear condom.  Enjoy sex responsibly!

We’d love to hear from you.  Do you get tested regularly?
