In the prenatal setting, microarray and conventional chromosome analysis is used for the investigation of fetal anomalies detected on ultrasound, high risk screening results, miscarriage and a familiy history of genetic conditions. Testing can be performed on CVS and amniotic fluid. For pregnancy loss, chromosome microarray or molecular karyotyping is used to investigate possible chromosomal causes of miscarriage. Microarray analysis has largely replaced conventional chromosome analysis, however chromosome analaysis may still be used for the investigation of familial chromosome rearrangements.

Rapid aneuploidy FISH testing can be performed on CVS and amniocentesis samples, if requested. Results are usually available within one business day of receipt.
Advanced notification is required for prenatal DNA testing for specific disorders.
