Does this test have other names?

TORCH screen

What is this test?


  • Toxoplasmosis. This infection is caused by a parasite commonly picked up from cat stools. Babies can develop congenital toxoplasmosis, which, if untreated, can cause blindness, deafness, seizures, and intellectual disability.


  • Rubella. Rubella, also called German measles, is a viral infection that can easily be passed from person to person through sneezing or coughing. Rubella is less common today because a vaccine protects against it, but pregnant women with rubella can pass the virus to a fetus. Rubella can cause miscarriage or stillbirth, as well as problems with growth of the fetus.



These infections can cause serious problems during pregnancy, so it's important to find them early in pregnancy so that they can be treated, if treatment is possible. Women often get the TORCH screening test at their first prenatal visit. If and when a woman has the TORCH screening is the doctor's decision.
