Fetal DNA

Fetal DNA refers to tiny genetic fragments from a developing baby that circulate in the mother's bloodstream. During pregnancy, some of the baby's cells break down and release their DNA into the mother's blood. Scientists can analyze this cell-free fetal DNA through a simple blood test, which helps assess the baby's genetic makeup. This method is used for non-invasive prenatal screening to detect potential genetic conditions such as Down syndrome, providing valuable information without the risks associated with invasive procedures like amniocentesis.
