Title: Increased amnionic fluid alpha-fetoprotein due to a holoacardium amorphous twin. Author: Harger JH, Doshi N, Marchese S, Hinkle RS, Garver KL. Journal: Clin Genet; 1981 Apr; 19(4):257-61. PubMed ID: 6168421. Abstract: Amnionic fluid alpha-fetoprotein measurement was employed as a screening test for neural tube defects in a pregnancy only at risk due to advanced maternal age. The alpha-fetoprotein concentration was elevated more than 10 standard deviations above the mean and was found to be caused by a holoacardium amorphous twin. A normal female fetus was also present. Various causes of elevated alpha-fetoprotein concentration in amnionic fluid are discussed.[Abstract] [Full Text] [Related] [New Search]
