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.

Laboratory Findings

  • There are no specific laboratory findings associated with spina bifida.
  • An elevated concentration of Maternal Serum Alpha-Fetoprotein may be predictive for contemporary detection of spina bifida.[1]

[Test] is usually normal among patients with [disease name].

  • Screening for spina bifida by mother's blood's AFP [alpha‐fetoprotein] is recommended for all pregnant women with Triple Test.[2][3]
  • Triple test looks for three specific substances: AFP, hCG, and Estriol.[2][4]
  • Triple test is performed between the 15th and 20th week of pregnancy preferably in the 16th -18th week.[2][4][3][5]
  • All pregnant women should have triple test dureng pregnancy, but is is more important in pregnants with:[2][4]
    • Family history of birth defects
    • Age of 35 years or older
    • Diabetes and use insulin
    • Viral infection during pregnancy
    • Exposure to high levels of radiation
  • 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]
