ToRCH is an acronym for a group of infections that can cause significant birth defects and even fetal death. For most ToRCH organisms, the initial screening test is based on the detection of antibodies to the organism. In most cases, IgG reactivity in the absence of IgM reactivity is indicative of a past infection, while IgM reactivity in the absence of IgG reactivity indicates a current infection. However, for some ToRCH diseases such as toxoplasmosis and CMV nfections, IgG avidity has recently been found to be useful for identifying primary infections. An IgG antibody produced in the first
few months following an initial infection has a lower avidity than an IgG antibody produced several months or years later; consequently, low-avidity antibody can be used to specifically identify high-risk mothers with a primary infection. To protect a fetus from ToRCH infection, early diagnosis through first trimester screening is critical.
