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.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
