Parental Sample Prep for Prenatal Microarray Testing
Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
In order to interpret equivocal array results on a prenatal sample (amniotic fluid or chorionic villus), parental studies are performed to determine if the abnormality detected on the prenatal array is inherited or de novo.
Maternal cell contamination testing is performed on the maternal blood and prenatal sample to detect the presence of maternal cells in the fetal sample.
