What do fetal karyotypes reveal?

Fetal karyotypes reveal the complete set of chromosomes in a fetus, allowing for the identification of chromosomal abnormalities such as aneuploidies (e.g., Down syndrome, Turner syndrome). This analysis typically involves examining cells from amniotic fluid or chorionic villus sampling. By assessing the number and structure of chromosomes, healthcare providers can diagnose genetic conditions and inform potential treatment or management options. Karyotyping is a crucial tool in prenatal genetic testing and counseling.
