What is Free-Cell DNA testing used for?

Free-Cell DNA testing is primarily utilized for assessing aneuploidy and chromosomal abnormalities in the fetus. This testing involves analyzing small fragments of fetal DNA that are circulating in the maternal bloodstream. By examining these fragments, clinicians can evaluate the risk of various chromosomal conditions, such as Down syndrome (trisomy 21) and other aneuploidies, which arise from the presence of an abnormal number of chromosomes.

The procedure is non-invasive, making it an attractive option for expecting parents who may wish to understand potential genetic conditions without the risks associated with more invasive tests, such as amniocentesis or chorionic villus sampling. The high sensitivity and specificity of Free-Cell DNA testing contribute to its proliferation in prenatal care, providing essential information regarding fetal health and development at an early stage of pregnancy.
