Each prenatal test request is unique and evaluated on an individual basis; additional requirements may apply. Though these guidelines may assist in the care of your patient, we strongly suggest contacting us to confirm arrangements PRIOR to the prenatal procedure. Making arrangements ahead of time is the best way to expedite testing for patients.
Please call (855) 831-7447 to speak with a laboratory genetic counselor prior to ordering prenatal testing.

Informed Consent for Prenatal Chromosomal Microarray Testing
- A maternal blood sample must accompany the prenatal sample to test for maternal cell contamination (MCC). A paternal sample may also be required (see below).
- The indications for prenatal testing must be specified on the requisition.
- Amniocyte and chorionic villus samples are acceptable for direct analysis for many molecular tests. However, a culture must be started either by the referring laboratory or by NTD Genetics. Culturing samples for molecular tests performed at NTD Genetics incurs a charge and must be specifically ordered.
