Trisomy 18

Trisomy 18 is caused by an extra 18th chromosome. It is a very serious birth defect causing many health problems and severe mental retardation. The AFP+ test indicates an increased risk for Trisomy 18 in only about 1 out of every 200 women. These women can have further testing to know for sure if the baby is healthy.
