Testing & Diagnosis for Congenital Toxoplasmosis in Children

Tests

The first step in treating your child is forming an accurate and complete diagnosis.

A blood test before or during pregnancy can determine if you have been exposed to the toxoplasma gondii parasite.

  • If you are infected, another type of test can determine whether your baby is infected.
  • In addition, fetal ultrasounds can determine if your baby's organs are damaged.

Currently, physicians in the United States do not routinely screen pregnant women for toxoplasma gondii, so if you suspect you may have been exposed to the parasite, ask your doctor to perform a blood test.

After we complete all necessary tests, Boston Children’s Hospital’s experts meet to review and discuss what they have learned. Then we will meet with you and your family to discuss the results and outline the best treatment options.
