There are no specific laboratory findings in the newborn associated with spina bifida. An elevated concentration of Maternal Serum [[Alpha-fetoprotein|Alpha-Fetoprotein]] may be predictive for contemporary detection of spina bifida. Screening for spina bifida by mother's blood's [[Alpha-fetoprotein|AFP]] [alpha‐fetoprotein] is recommended for all pregnant women with Triple Test. Triple test looks for three specific substances: AFP, hCG, and Estriol. Triple test is performed between the 15th and 20th week of pregnancy preferably in the 16th -18th week. | |||

Overview
There are no specific laboratory findings in the newborn associated with spina bifida. An elevated concentration of Maternal Serum Alpha-Fetoprotein may be predictive for contemporary detection of spina bifida. Screening for spina bifida by mother's blood's AFP [alpha‐fetoprotein] is recommended for all pregnant women with Triple Test. Triple test looks for three specific substances: AFP, hCG, and Estriol. Triple test is performed between the 15th and 20th week of pregnancy preferably in the 16th -18th week.

- In patients with high level of AFP, use of ultrasound and amniocentesis may be useful to diagnose open neural tube defects including spina bifida.[4][3][5]
