Overview
The primary purpose of the TORCH Panel IgM test is to identify women with a recent or acute TORCH infection during pregnancy. It helps assess the risk of congenital transmission and allows for timely intervention or follow-up testing. The test measures IgM antibodies produced by the body in response to Toxoplasma gondii, Rubella, Cytomegalovirus, and Herpes Simplex Virus types 1 and 2.

Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"A positive TORCH IgM result should never be interpreted in isolation. It requires correlation with clinical findings and confirmatory tests such as PCR and IgG avidity to determine the actual risk of fetal infection."

Test Parameters & Specifications
Sample Stability
- Haemolysed samples
- Improperly labelled specimens
- Samples received beyond the recommended stability period
Understanding Your Results
Negative: No recent infection. Positive: Recent or acute toxoplasmosis.
Negative: No recent infection. Positive: Recent rubella infection or vaccination.
Negative: No recent infection. Positive: Recent or active CMV infection.
Negative: No recent infection. Positive: Recent HSV-1 infection.
Negative: No recent infection. Positive: Recent HSV-2 infection.
If your TORCH Panel IgM test is positive for any pathogen, consult your gynecologist or infectious disease specialist promptly for further evaluation. Pregnant women should seek immediate fetal risk assessment and counselling.
Limitations
- ⚠IgM antibodies can persist for months after primary infection, limiting its specificity for acute infection.
- ⚠A positive IgM result alone does not confirm fetal infection; confirmatory testing is required.
- ⚠In immunocompromised patients, IgM response may be delayed or absent.
Risks & Considerations
- ●Minimal risks associated with routine blood draw, such as slight pain, bruising, or lightheadedness.
Interfering Factors
- ●Rheumatoid factor and high IgG concentrations may cause false-positive IgM results.
- ●Recent blood transfusion or immunosuppressive therapy may affect antibody levels.
- ●Cross-reactivity from other herpes viruses (e.g., EBV, VZV) can occur.
Compare With Similar Tests
| Test | Torch Panel IgM Test | TORCH Panel IgG | PCR for TORCH Pathogens | IgG Avidity Test |
|---|---|---|---|---|
| Comparison | Torch Panel IgM Test | IgG antibodies indicate past infection or immunity, whereas IgM indicates recent infection. | PCR detects pathogen DNA/RNA directly and is more specific for active infection. | IgG avidity helps distinguish recent from past infection; low avidity suggests recent infection. |
