The following tests make up the TORCH panel: Toxoplasmosis, Rubella, Cytomegalovirus, and Herpes simplex virus.
- Toxoplasmosis is a parasitic infection that can be passed from mother to baby through the placenta during pregnancy.
- Rubella is the virus that causes German measles.
What happens when TORCH test is positive?

What causes TORCH infections?

CMV is mainly spread through close contact with someone who already has CMV. It can be passed on through sexual contact and contact with other body fluids including saliva, blood, breast milk, tears, pee and poo. CMV can only be passed on when it’s “active”.
What if TORCH test is negative?
A negative test result is considered normal. This means no antibodies were detected, and there’s no current or past infection. There are many reasons why IgM antibodies may be present. If you test positive for IgM antibodies during pregnancy, more testing will be done to confirm an infection.

Transmission can also occur from an infected mother to her fetus or newborn and by blood transfusion and organ transplants.
Is CMV serious?
For people who have weakened immune systems, CMV infection can be serious or even fatal. People who have undergone stem cell or organ transplants seem to be at greatest risk. You develop a mononucleosis-like illness while you’re pregnant.
Is CMV a STD?
While all members of the herpes virus family are contagious, CMV isn’t considered a sexually transmitted infection (STI) like certain forms of herpes simplex are. Additionally, CMV is considered the only member of the herpes virus family to spread directly from mother to child through the placenta during pregnancy.
What is the normal range of TORCH test?

|---|---|
| 20.0 – 24.9 AU/mL: | Indeterminate – Repeat testing in 10-14 days may be helpful. |
| 25.0 AU/mL or greater: | Detected – IgM antibody to rubella detected, which may indicate a current or recent infection or immunization. |
What is Torch IgG and IgM test?
TORCH IGG/IGM DIAGNOSIS (National) The TORCH test consists of tests for antibodies detection to four organisms that cause congenital infections transmitted from mother to fetus: Toxoplasma gondii (toxoplasmosis), rubella (German measles), cytomegalovirus (CMV), and herpes simplex virus (HSV).

Which tests are used for torch screening?
Methods of TORCH screening vary. IgM level detection was one of the earlier methods for screening and remains a commonly used test.4,5,6)Previously, complement fixation tests (CFTs) for CMV and HSV and hemagglutination inhibition (HI) for rubella have been used.
