Chromosome aberrations observed in the CVS specimen but not in the fetus (confined placental mosaicism) occurs in approximately 1% of cases.

This test will detect chromosome abnormalities of the fetus including numerical, structural, and mosaic abnormalities. Chromosome analysis will also reveal fetal gender and sex chromosome abnormalities. Indications for prenatal chromosome analysis may include advanced maternal age, abnormal fetal ultrasound, abnormal maternal serum screen, abnormal cell-free DNA results, history of a previous child with a chromosome abnormality, or a parent who carries a balanced chromosomal rearrangement or has another chromosome abnormality.
