No, there isn’t any such prenatal screening test available. Autism spectrum disorder is a neurodevelopmental disorder characterised by persistent deficits in communication and interaction, and certain repeated patterns of behaviour or activities.
ASD is more common amongst children with certain genetic conditions than in the general population. These include conditions lsuch as fragile X and Angelman syndrome for which there is screening available. However, the vast majority of children with autism spectrum disorder may not have any clear identifiable genetic condition.
