Chromosome Analysis, Chorionic Villus with Reflex to ClariSure®, Oligo‑SNP, Prenatal

Use

Testing determines chromosomal status of the fetus. Numerical and structural chromosomal abnormalities can be diagnosed. Sex and the presence of more than one cell line (mosaicism) can also be determined. Indications include diagnosis of chromosome abnormalities in fetuses of women who are of advanced maternal age; had a previous child with a chromosome abnormality; parental carrier of a balanced translocation, inversion or marker chromosome; parental mosaicism. Chromosomal microarray (ClariSure® Oligo‑SNP) may be performed for further investigation of abnormal ultrasound findings, further definition of imbalanced cytogenetic abnormalities, investigation of equivocal cytogenetic findings, characterization of supernumerary marker chromosomes, follow‑up to familial genomic alterations, or family history of phenotypic abnormalities.
