Maternal Serum Alpha-Fetoprotein Screening
Background: The maternal serum alpha-fetoprotein test (MSAFP) was developed to screen for neural tube defects. Little is known about the adoption of the MSAFP test. This study examines the effect of provider specialty and geographic location and patient insurance status on MSAFP test use in Washington State. Methods: We conducted a retrospective cohort study of MSAFP use in low-risk obstetric p...
متن کاملPrenatal fetal karyotyping and maternal serum alpha-fetoprotein screening.
Prenatal karyotyping was undertaken in 569 consecutive amniotic fluid samples where the indication for amniocentesis was two sequential raised maternal serum alpha-fetoprotein concentrations. In 475 successful cultures five chromosome abnormalities were found--four constitutional anomalies (47,XXY; 47,XYY; an inherited inv(8) (p23q11); and a de-novo translocation t(6;7) (p11;p22) and a culture-...

pheochromocytomas are cathecolamine producing tumor arising from chromaffin cells of adrenal medulla and extra adrenal tissues. this is a report of a boy presented with headache and hypertension. in radiologic exams, an adrenal mass detected in the left side, with no renal tissue on that side. it was reported an adrenal pheochromocytoma in histopathology. renal agenesis confirmed during surgery...
متن کاملSerum alpha-fetoprotein: II. Clinical evaluation of two automated immunoassays for maternal serum screening.
A prospective clinical evaluation is reported for analysis of maternal serum alpha fetoprotein (s.AFP) testing by recently developed enzymeimmunoassay automated systems. The reference method for the study was a manual competitive binding radioimmunoassay which has been utilized by us in the Maternal Serum AFP Screening Program at the Medical University of South Carolina for the past five years....
متن کاملEvaluationof Four “Kit” ImmunoassayMethodsfor Determination of Aipha-Fetoproteinin Serum duringPregnancy
We evaluated four immunoassay methods for determination of alpha-fetoprotein in serum. All are commercially available in kit form in North America and we find them acceptable with respect to sensitivity, stability, precision, linearity, and analytical recovery. For the Dainabott method, the median values from 16 through 20 weeks of gestation are 34.4, 38.1, 42.1, 51.4, and 66.3 tg/L for each we...
