One of the primary benefits of cffDNA testing is its non-invasive nature, which poses no risk to the fetus compared to invasive procedures like amniocentesis or chorionic villus sampling (CVS). Additionally, it has a high accuracy rate for detecting common chromosomal abnormalities. However, it is important to note that cffDNA testing is a screening test, not a diagnostic one. This means it cannot definitively diagnose a condition but can indicate the likelihood of its presence. A positive result often requires further diagnostic testing to confirm the findings.
