Screening and Diagnosis

Diagnosing autism spectrum disorders (ASDs) can be difficult, since there is no medical test, like a blood test, to diagnose the disorders. Doctors look at the child’s behavior and development to make a diagnosis.
ASDs can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered very reliable. However, many children do not receive a final diagnosis until much older. This delay means that children with an ASD might not get the help they need.

Developmental Screening
Developmental screening is a short test to tell if children are learning basic skills when they should, or if they might have delays. All children should be screened for developmental delays and disabilities during regular well-child doctor visits at:

  • 9 months
  • 18 months
  • 24 or 30 months

Additional screening might be needed if a child is at high risk for developmental problems due to preterm birth, low birth weight or other reasons.
It is important for doctors to screen all children for developmental delays, but especially to monitor those who are at a higher risk for developmental problems due to preterm birth, low birth weight, or having a brother or sister with an ASD.
