Randomized trial compares IGF-I measurement methods in various conditions, suggesting enhanced accuracy using truncated radioligands.

This research aims to improve IGF-I and IGF-II measurement accuracy by comparing extraction methods and radioligands.
Measured IGF-I using truncated IGF-I and IGF-I as radioligands in acid ethanol extracts and acid gel filtrates.
Analyzed samples from healthy subjects and individuals with acromegaly, growth hormone deficiency, or Type I diabetes.
Utilized cryo-precipitation to separate serum in the extraction processes.
IGF-I measurements using truncated IGF-I showed strong correlation in healthy subjects (N=42, r=0.91, p<0.001).
Inacromegaly and GH deficiency, truncated IGF-I as radioligand yielded a significant correlation compared to the conventional method (p<0.01).
IGF-I concentrations with IGF-I as radioligand were inaccurately elevated by 112% in GH deficiency, indicating substantial measurement error.

Bang et al. (1991) studied this question.
