The method is based on the catalytic effect of selenium on the reduction of tetranitro blue tetrazolium by dithiothreitol; it is simple, rapid and effective with several forms of selenium. With this catalytic assay, 1.2 ng of Se as selenite, 21 ng of Se as selenocysteine or 150 ng of Se as selenocys
