The results can identify small amounts of missing or extra chromosomal material. These imbalances can lead to various genetic disorders, but the interpretation of the results can sometimes be complex and will require the expertise of a genetics specialist.

The risks are minimal and are mainly associated with the blood draw. These can include slight pain or bruising at the injection site.

No specific preparation is needed for this test.
