Method:

A chromosome microarray is a powerful tool used to look at sub microscopic changes in our genetic information that may impact health or development. Microarray is considered the gold standard test for the investigation of intellectual disability and developmental and behavioural concerns such as autism spectrum disorders and congenital malformations.

Please note, a conventional chromosome analysis or specific Prader-Willi/Angelman syndrome test can not be performed at the same time as a microarray analysis due to Medicare constraints.

A conventional chromosome analysis is recommended for neonates with suspected trisomy eg. Down syndrome.
