Objectives: GH measurements during OGTT have profound effects on therapy and follow-up management of acromegaly. To minimize the discordance between immunoassays, it is recommended to calibrate them using 22 kDa-GH-preparation instead of the use of pituitary-derived calibrants. The aim of our study was to evaluate the between-method discrepancies in GH determinations by assays using different calibrants considering further confounders like age, gender, and BMI.<p class="ab...

Objectives: Besides the measurement of IGF-1, GH suppression during OGTT to assess the biochemical status in acromegaly is recommended. However, as a consequence of the development of highly sensitive and specific GH assays a critical re-evaluation of the criteria for the diagnosis and follow-up management of acromegaly is mandatory. The aim of our study was to evaluate the between-method discrepancies in GH determinations by different immunoassays considering further confound...
