cell-free fetal DNA (cfDNA)

Cell-free fetal DNA (cfDNA) refers to tiny fragments of genetic material released into a pregnant woman's bloodstream by the developing fetus. This DNA can be detected as early as the 10th week of pregnancy. cfDNA testing is a non-invasive method used to screen for certain genetic conditions, such as Down syndrome, in the fetus. The process typically involves taking a blood sample from the mother, which is analyzed in a lab. This testing has become a valuable tool for expectant parents seeking information about their baby's health without the risks associated with invasive procedures.
