What is the fastest way to get info on baby that might have spina bifida?

Diagnosis?: If your question means how does one get diagnosis of spina bifida during pregnancy, a well-performed ultrasound can provide that information as early as the second trimester. Amniotic fluid can have elevated enzymes associated with spina bifida which requires removing fluid from the uterus & some risk. This is slower but provides complementary information to ultrasound in questionable cases.
