Reference values for IGF-I serum concentration in an adult population: use of the VARIETE cohort for two new immunoassays

Objective Measurement of IGF-I is important in the management of patients with growth hormone disorders. Here we aim to establish normative data for two new IGF-I assay kits based on a large random sample of the French general adult population. Subjects and methods We measured IGF-I in 911 healthy adults (18–90 years) with two immunoassays (ROCHE Elecsys ® and IMMULITE-2000 calibrated against the new IS 02/2547). We compared the data with those...
