STI Panel

The 10 tests in this panel

What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

• HIV-1/2 Antigen/Antibody (4th Generation)

  A blood test that looks for HIV antibodies and a viral protein (p24), so it can find an infection earlier than tests that only look for antibodies.

• RPR (Rapid Plasma Reagin)

  A blood test used to help find syphilis and to follow its treatment. A reactive result needs a second, more specific test to confirm it.

• Syphilis Antibody, Treponemal

  Looks for antibodies to the bacterium that causes syphilis. It usually stays positive for life after an infection, even a treated one.

• Chlamydia trachomatis NAAT

  A urine test that looks for the genetic material of the bacteria that cause chlamydia, a common sexually transmitted infection.

• Neisseria gonorrhoeae NAAT

  A urine test that looks for the genetic material of the bacteria that cause gonorrhea, a common sexually transmitted infection.

• Trichomonas vaginalis NAAT

  A test that looks for the genetic material of Trichomonas vaginalis, the parasite behind trichomoniasis, a common and curable sexually transmitted infection.

• Hepatitis B Surface Antigen (HBsAg)

  A protein from the hepatitis B virus. A positive result is linked to the virus being in your blood now, from a recent infection or a long-term one.

• Hepatitis C Antibody

  Checks for antibodies your immune system makes after hepatitis C exposure. A reactive result is followed by an RNA test to see if the virus is still there.

• Herpes Simplex Virus 1 IgG (Type-Specific)

  Looks for IgG antibodies to herpes simplex virus type 1 (HSV-1), the usual cause of cold sores. A positive result means you were infected at some point.

• Herpes Simplex Virus 2 IgG (Type-Specific)

  Looks for IgG antibodies to herpes simplex virus type 2 (HSV-2), a common cause of genital herpes. A low positive result often needs a second test to confirm.

Labs can include one more test in this panel that we haven’t written up yet.
