What does a positive IgM test indicate regarding TORCH infections?

A positive IgM test indicates a recent infection and a potential risk to the baby concerning TORCH infections, which include Toxoplasmosis, Other infections, Rubella, Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV).

In the context of infectious diseases, the presence of IgM antibodies usually signifies that the body has recently responded to an infection. This is particularly significant in the case of TORCH infections during pregnancy, as a recent infection in the mother can pose serious risks to fetal development.

For instance, if a pregnant woman tests positive for IgM antibodies against any of the TORCH pathogens, it suggests that the infection occurred during her current pregnancy or shortly before conception, heightening the concern for adverse outcomes such as congenital anomalies or other complications in the newborn. Therefore, understanding the implications of a positive IgM test is critical in prenatal care and risk assessment for both the mother and the baby.
