Test Description:

Maternal cell contamination (MCC) studies.

The potential presence of maternal cells within a prenatal specimen (amniotic fluid, CVS, cord blood, products of conception) causes risk for interpreting DNA based test results inaccurately. To have complete confidence that the test results are indicative of the fetal DNA, the maternal blood genotype is compared to the fetal genotype, derived from amniocytes, chorionic villi, cord blood, or products of conception. This assay assesses at least 13 chromosomal markers utilizing a PCR-based assay. This study detects and quantifies the presence of maternal DNA within the prenatal sample.
