摘要: Prospective evaluation through the use of radioimmunoassay β -subunit human chorionic gonadotropin ( -hCG) in blood samples obtained during first 30days gestation was performed on an infertile population at high risk for pregnancy loss. Four hundred and fourteen 281 pregnancies were analyzed. On basis single, random -hCG asymptomatic patients, 77% successful 59% abortions correctly identified. doubling time (mean 2.2days±1.0 [2 SD]) computed from serial sampling, again 88% 76% appears to provide a reliable method evaluating early prognosis with significantly greater ability identify problem within than does single hCG values.
