Maternal blood screening can detect an elevated risk for spina bifida by measuring levels of alpha-fetoprotein (AFP) in the mother's blood, but it cannot diagnose the actual condition in the fetus. Ultrasound sonography can sometimes detect physical abnormalities associated with spina bifida, but it may not always be definitive. Amniocentesis and chorionic villi sampling involve analyzing fetal cells and can diagnose spina bifida, but they are not specifically designed to detect an elevated risk for the condition.
