摘要:
Objectives. We questioned whether race-specific databases for maternal serum alphafetoprotein (MSAFP) screening should be added to those already available for African-American and white patients. Study design. We analyzed 138,272 MSAFP samples. The geographic origin of the samples was New York metropolitan area. Patients were classified as white, African-American, Hispanic or Asian. The usual adjustments were made and groups compared. Statistical analysis included ANOVA and multiple comparison test. Results. MSAFP values are highest (p < 0.05) for Asians, followed by African-Americans, Hispanics, and whites, although the difference between Hispanic and white was not significant. Conclusions. Four separate databases are definable if specimen quantity is sufficient. Race/ethnic specific databases are more likely to yield the most accurate detection of abnormal MSAFP values, and therefore, fetal anomalies.
