First trimester intact hCG as an early marker of trisomy 21: a promise unrecognised?

abstract：OBJECTIVES:To determine the cost effectiveness of a universal prenatal screening program for alpha- and beta-thalassaemia. METHODS:We retrospectively reviewed our program from 1998 to 2002, and calculated the direct and indirect costs of various components. RESULTS:18,936 women were screened at our prenatal clinic an...
