This test detects clinically significant large (whole chromosome) and submicroscopic (microdeletion/microduplication) copy number changes throughout the genome in fetal cells after a pregnancy loss.
Test details and complementary testing
- In addition to fetal tissue, a maternal blood sample is requested to rule out maternal cell contamination, which ensures that the microarray results are representative of the fetus rather than the mother.
- Prenatal Microarray should be ordered instead of this test to analyze fetal cells during a pregnancy.
- Postnatal testing on maternal, paternal, or newborn blood after delivery, including Postnatal Chromosome Analysis, Postnatal FISH, or Postnatal Microarray, must be ordered separately.
