The 7 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.

  • Toxoplasma gondii IgG

    Measures long-lasting IgG antibodies to the Toxoplasma parasite. A positive result means past exposure, not necessarily a recent infection.

  • Toxoplasma gondii IgM

    Looks for IgM antibodies to the Toxoplasma parasite. They appear early in an infection but can linger for a year or more.

  • Rubella IgG

    Shows whether you have antibodies to the rubella (German measles) virus, from vaccination or past infection. Often checked before or early in pregnancy.

    Adults
    10 and above IU/mL

  • Cytomegalovirus (CMV) IgG

    A blood test for antibodies that show whether your immune system has met cytomegalovirus (CMV), a very common virus, at some point in your life.

  • Cytomegalovirus (CMV) IgM

    Looks for IgM antibodies that often appear early in a new CMV infection, but can also stay positive for months or come back falsely positive.

  • 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.
