Overview

There are no specific diagnostic laboratory findings associated with an intellectual disability however, laboratory tests like imaging, genetic testing, chromosomal analysis, and enzyme levels assessment are done to determine possible cause of ID.

Laboratory Findings

It is challenging to completely examine children with intellectual disabilities due to inadequate communication skills. Some malformations may be missed even with a comprehensive examination. Some malformations such as atrial septal defect (ASD), single kidney, holoprosencephaly, visual and hearing impairment may be missed. ^[1]
