Abstract
The measurement of insulin is a useful adjunt to the glucose tolerance test as an aid to the diagnosis of diabetes mellitus or prediabetic syndromes. Insulin measurements also essential for the differential diagnosis of insulinoma or other hypoglycemic ststes. We have evaluated the automated Insulin assay on the IMx instrument(Abbott Labs.). Our evaluation of the insulin test by MEIA was: 1. Within-run & Between-run precision of insulin expressed in coefficient of variation(C.V.) were the range of 3.23% to 2.31% and 3.69% to 3.02%, respectively. 2.The comparison study for insulin indicated good correlation between MEIA(X) and RIA(Y), correlation sfficient(r) was 0.96, regression with RIA(Y) was Y=1.0233 x X -1.1384. Our conclusion is that insulin by MEIA method showed relatively good precosion, easy to operate, fully automated and shwed good correlation with RIA method.
