Currently, prenatal screening and autism are not directly linked through a single, definitive test. While researchers have made strides in identifying genetic markers associated with autism, most screenings during pregnancy are designed to detect broader chromosomal anomalies, not specific developmental outcomes.

Test accuracy of existing screenings for autism remains limited. While some forms of prediction are possible through advanced genetic analysis, such as detecting rare mutations or deletions, they do not guarantee a diagnosis. Most cases of autism involve complex interactions between genes and environment, which can’t yet be captured fully through current prenatal screening and autism tools. However, such screenings can still be valuable in guiding closer developmental monitoring and earlier access to support services after birth.

What to Look Out for Postnatally

Although prenatal predictions are still evolving, early behaviours in infancy or toddlerhood can provide clearer insights into a child’s developmental profile.

Limited social engagement

Children may avoid eye contact, smile less frequently, or show little interest in faces.

Repetitive play or routines

A child might line up toys, repeat actions, or insist on sameness in daily activities.

Delayed language development

Speech may come later than expected, or a child may struggle with back-and-forth communication.
