About This Test
Who Should Get This Test
The test is used to screen pregnant women for prior or current TORCH infection, to identify those at risk of transmitting infection to the fetus, and to guide further testing and management.
How to Prepare
- No fasting or special preparation required.
- Inform the phlebotomist if you are pregnant, have recently had a blood transfusion or immunoglobulin injection, or have a known immune disorder.
- For free home sample collection, please schedule the collection before 9 am to get a same-day report.
- Wear loose sleeves so the phlebotomist can easily access the vein.
Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"A positive TORCH IgM must never be interpreted as fetal infection without confirmatory testing. Interpret results in the context of gestation, clinical symptoms and serial serology."

Test Parameters & Specifications
Sample Stability
- Grossly hemolysed or icteric sample
- Clotted sample
- Mislabeled or unlabeled sample
- Sample received outside the recommended stability period
Understanding Your Results
Past infection or immunisation. Usually indicates immunity rather than active infection.
No detectable antibodies; patient is susceptible. If clinical suspicion is high, repeat testing after 2–3 weeks is recommended.
Possible recent or primary infection. Confirmatory testing such as IgG avidity, immunoblot, PCR or serial antibody testing is needed.
Possible acute infection or false-positive IgM. Additional testing on a new sample is required before concluding fetal risk.
If you are pregnant and have any positive or equivocal TORCH IgG or IgM result, consult your obstetrician, maternal-fetal medicine specialist, or infectious disease physician promptly. Do not delay decisions based on a single IgM result.
Limitations
- ⚠IgM-positive result alone does not accurately predict the risk of fetal infection.
- ⚠A positive TORCH IgM should be considered only as a starting point; confirmatory evaluation is required.
- ⚠The panel does not detect the organism directly; PCR or culture may be needed for active infection.
- ⚠Reference ranges and cut-off values vary between laboratories and commercial kits.
- ⚠Seroconversion may be delayed, so repeat testing after 2–3 weeks may be required.
Risks & Considerations
- ●Minor bruising or pain at the puncture site
- ●Dizziness or faintness during blood collection
- ●Very rare infection or excessive bleeding
Interfering Factors
- ●Recent infection during the incubation period may produce false-negative IgM before antibodies appear.
- ●Cross-reacting antibodies from other herpes viruses can cause false-positive CMV or HSV IgM results.
- ●Passive maternal IgG in newborns can give a positive IgG result without congenital infection.
- ●Blood transfusion, prior immunoglobulin administration or immunocompromised status may alter antibody levels.
