Test Details: Chromosomal aneuploidy is a condition where a person has an abnormal number of chromosomes. It can affect any pregnancy and can cause a variety of birth defects. Quantitative fluorescent polymerase chain reaction (QF-PCR) detects chromosomal aneuploidies in a person's DNA. It screens for common aneuploidies like Trisomy 13, 18, and 21 and can be done during pregnancy and after birth. Chromosomal Microarray Analysis (CMA) can measure DNA gains and losses across the genome and detect sub microscopic abnormalities that are too small to be seen by traditional methods. The panel offers a comprehensive analysis of chromosomal abnormalities.
