The TORCH IgG & IgM Test detects IgG and IgM antibodies against several infections that can affect pregnancy, including Toxoplasma, Rubella, Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV). These infections can lead to birth defects in newborns and illness in adults.
- IgM antibodies in the newborn indicate a high likelihood of an active infection with that organism.
- IgM antibodies produced by the mother cannot cross the placenta, so their presence in the infant strongly suggests active infection in the baby.
- The presence of IgG and absence of IgM in the infant may indicate passive transfer of antibodies from the mother and does not suggest an active infection.
- In the pregnant woman, the presence of IgM antibodies suggests a new or recent infection with the virus or parasite, requiring further investigation.
This test helps assess the risk of these infections during pregnancy and their potential impact on both maternal and fetal health.
