Determination of free and total insulin and C-peptide in insulin-treated diabetics

Women and men have similar amounts of liver and intra-abdominal fat, despite more subcutaneous fat in women: implications for sex differences in markers of cardiovascular risk

“…Serum-free insulin concentrations were measured using the Auto-DELFIA kit (Wallac, Turku, Finland). C-peptide concentration was determined by RIA [27]. HbA 1 c was measured by HPLC using the fully automated Glycosylated Hemoglobin Analyzer System (BioRad, Richmond, Calif., USA) [28].…”

Cholesterol synthesis is increased and absorption decreased in non-alcoholic fatty liver disease independent of obesity

“…Serum free insulin concentrations were measured using the Auto-DELFIA kit (Turku, Finland), and serum C-peptide concentrations were calculated using the radioimmunoassay [22]. HbA 1c was measured with high pressure liquid chromatography (Rio-Rad, Richmond, CA).…”

Insulin glargine or NPH combined with metformin in type 2 diabetes: the LANMET study

“…Serum concentrations of GAD antibodies [14] and C-peptide [15] were determined by RIA. S-ALT, S-AST and S-AFOS activities were determined according to the recommendations of the European Committee for Clinical Laboratory Standards.…”
