  1. Glucagon and IGF1 were measured by radioimmunoassay (RIA); ACTH, cortisol, and growth hormone were measured by chemiluminescent enzyme immunoassay (CLEIA); adrenalin, noradrenalin, and dopamine were measured by High Performance Liquid Chromatography (HPLC)
  2. aReference range of Insulin growth factor 1 (IGF1) for 77 years old male. The reference range of IGF1 is differ by age and sex, only up to 77 years old
