The NIPT (Non-Invasive Prenatal Testing) is a blood test for pregnant individuals that screens for common chromosomal abnormalities in a developing baby, such as Down syndrome, by analyzing fetal DNA fragments in the mother's blood.
 
It is a reliable screening test performed from the 10th week of pregnancy, can also determine the baby's sex, and provides a "high-chance" or "low-chance" result, with high-chance results requiring further diagnostic testing for confirmation
