What are the tests for neural tube defect?
5 doctors weighed in across 2 answers
Neural tube defects: The primary test is the maternal serum fetal protein. If that is abnormal, an ultrasound examination and perhaps an amniocentesis.

Ultrasound, MSAFP.: Prenatal ultrasound should have >90% sensitivity for open neural tube defect detection around 20 weeks. Earlier (>16 weeks) risk stratification can occur with screening maternal blood for AFP - although that is not diagnostic and has to be followed by ultrasound for confirmation and/or differential diagnosis. Fetal MRI is used as part of evaluation for possible fetal surgery to treat spina bifida.
