Frequent blood sampling with serum GH measurement shows that in normal subjects (left panel) GH can fluctuate between undetectable levels (most of the time) and peaks of up to 30 μ g/l (90 mIU/l), owing to the episodic nature of GH secretion, while in patients with acromegaly (an example is given on right panel), GH hypersecretion is continuous and GH never returns to undetectable levels.
