Screening selected blood donors with biochemical iron overload for hemochromatosis: a regional experience.

Abstract

This study is an example of a large, two-step hemochromatosis screening with moderate effort and low cost, that enriches basal C282Y allele frequency by about three-fold. Screening based on genotyping only subjects found to have a TS>45% is feasible but, in order to be cost effective should be based on the identification of the two prevalent mutations even in an area where several forms of hemochromatosis have been reported.
