ReviewPrenatal diagnosis of chromosomal imbalances.
Prenatal array comparative genome hybridisation (aCGH) testing has by and large replaced routine karyotyping in many healthcare settings.

This is the case for aCGH in any setting, but we discuss the particular challenges the prenatal setting generates and suggest areas that need further debate and discussion as well as some pragmatic ways forward.
