Abstract

A radioassay procedure and reagent kit therefor for detecting auto blocking antibody, such as auto blocking antibody which interferes with the complexation of intrinsic factor with vitamin B.sub.12. A receptor, i.e., intrinsic factor, is immobilized on a support and the amount of ligand, i.e., vitamin B.sub.12, capable of binding therewith in the presence of a biological fluid sample is determined.
