<正> Objective:To study the changes of true insulin(TI) and immunoreactive insulin (IRI) in subjectswith NGT, IGT and DM, to study the difference betwee true insulin and immunoreactive insulin in evaluating β-cell function and insulin sensitivity. Methods: The levels of serum IRI and TI were determined in 54 cases with typeⅡ diabetes mellitus(Group DM),43 cases with impaired glucose tolerance (Group IGT) and 75 cases with normalglucose tolerance (Group NGT). Then every group was subdivided into obese and non-obese subgroups according tobody mass index. IRI was determined by RIA. TI was determined by ELISA using monoclonal antibody with no sig-nificant cross-reaction between insulin and proinsulin. The insulin resistance index (Homa-IR), pancreatic β-cell
