cell-free fetal DNA

Cell-free fetal DNA (cffDNA) refers to tiny fragments of genetic material from the fetus that are present in the mother's bloodstream. During pregnancy, these DNA fragments are released into the mother's blood as fetal cells break down. Medical tests can analyze these fragments to assess the fetus’s genetic information, helping detect conditions like Down syndrome or other chromosomal abnormalities. This process is non-invasive, meaning it involves a simple blood draw from the mother, making it a safer alternative to traditional invasive tests. cffDNA provides valuable insights into fetal health without posing risks to the pregnancy.
