What it is

The TORCH Panel, IgM Panel is a blood test that detects IgM antibodies against a group of infections known as TORCH. These include Toxoplasmosis, Other infections (such as syphilis, varicella, parvovirus B19), Rubella, Cytomegalovirus (CMV), and Herpes simplex virus (HSV). The presence of IgM antibodies usually indicates a recent or active infection.

Uses

This test is mainly used in pregnant women to screen for infections that may affect the developing baby. It helps in diagnosing recent maternal infections that can cause congenital abnormalities, miscarriage, or stillbirth. It is also used in newborns with suspected congenital infections.

Symptoms That May Lead to the Test

Doctors may recommend this test if a pregnant woman has symptoms such as fever, rash, lymph node swelling, or flu-like illness. In newborns, it may be advised if there are signs of growth retardation, jaundice, microcephaly, seizures, hearing loss, or eye problems.

Abnormal Results

Positive IgM: Indicates a recent or active infection with one or more TORCH organisms. This may require further confirmatory testing and clinical correlation.

Negative IgM: Suggests no recent infection. However, past infection or immunity can only be confirmed by testing IgG antibodies alongside IgM.

Risks

The TORCH IgM Panel is a routine blood test with minimal risks. Possible side effects include mild pain, bruising, or bleeding at the puncture site, and rarely dizziness or infection.
