Welcome to AccessAtlanta!

A blood test that screens for several congenital infections including Toxoplasmosis, Rubella, Cytomegalovirus, Herpes simplex (hence the name) and other infections.

How the Test is Performed

Infant or young child:
The area from which blood will be drawn (usually finger) is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued bleeding.

How to Prepare for the Test

For specific information regarding how you can prepare your child, see the following: infant test or procedure preparation (birth to 1 year).

How the Test will Feel

While the blood sample is being obtained, your child will most likely feel a prick and a brief stinging sensation.

Why the Test is Performed

This test is used to screen infants for certain congenital infections (infections transmitted from mother to fetus/newborn via the placenta). Infections like toxoplasmosis, cytomegalovirus, herpes simplex, syphilis and others may lead to malformations, growth delay, and neurological dysfunction. The TORCH screen is one way to assess whether your child has a congenital infection. In some cases, the mother may also need to be tested to help diagnose certain congenital infections.
