Maternal Serum Screening and Amniotic Fluid Assays *
WHY IS AFP TESTING IMPORTANT?
This test is recommended for screening of neural tube defects and detects 95-100% of anencephaly and 80-90% of spina bifida.
WHAT IS A NEURAL TUBE DEFECT?
Defects in the development of the brain (called anencephaly) or the spinal cord (called spina bifida) are collectively described as neural tube defects (NTDs). Almost all babies with anencephaly die within hours or days of birth. Those born with spina bifida often survive, but because of damage to the spinal cord the vast majority develop handicaps varying from total paralysis from the waist down (associated with lack of bladder and bowel control) to some cases with only mild impairment of walking. Hydrocephalus (an accumulation of fluid in the brain) occurs in 80-90% of these children. Affected children with spina bifida require continuous medical and surgical care and often have a shorter life span. Mental retardation is a frequent complication.
