The TORCH Screen Test is a blood test used to detect infections that could cause complications during pregnancy. "TORCH" stands for Toxoplasmosis, Other (like syphilis, varicella-zoster, parvovirus B19), Rubella, Cytomegalovirus (CMV), and Herpes simplex virus (HSV). These infections can be transmitted from mother to fetus and may lead to serious birth defects or pregnancy complications if not detected and managed early.
Below, you will find detailed information about the test's purpose, how it works, preparation and procedure, result interpretation, and potential risks.
Purpose of the TORCH Screen Test
The TORCH test helps detect infections that could harm a fetus during pregnancy. Early detection allows doctors to plan appropriate treatments or interventions.
This test helps:
- Identify active or past infections in the mother
- Prevent fetal complications such as miscarriage, developmental delays, or congenital anomalies
- Guide treatment plans to manage infections during pregnancy
- Monitor immune status for conditions like rubella immunity

How Does the TORCH Screen Test Work?
The TORCH Screen Test detects antibodies in your blood that show if you have a current or past infection with any of the TORCH group of infections.
Step-by-Step Process:
-
Sample Collection
A healthcare professional will clean the area, usually inside your elbow, and draw a small blood sample from a vein. -
Laboratory Analysis
The blood sample is sent to a lab, where it is tested for IgM antibodies (indicating recent infection) and IgG antibodies (indicating past infection or immunity) against the TORCH infections. -
Result Interpretation
Based on antibody levels, your doctor determines if you have an active infection, past exposure, or immunity. -
Duration
The blood draw takes only a few minutes. Laboratory testing typically takes 1 to 3 days to provide results.
