IGF-1 is a protein that reflects growth hormone (GH). The value falls with age and is used as a measure of anabolic signalling and ageing.
In adults the value is of interest for investigating growth hormone deficiency or excess. It is also discussed as a marker in longevity research.
What does low IGF-1 mean?
Low IGF-1 in adults can suggest growth hormone deficiency.
What does high IGF-1 mean?
Very high IGF-1 in adults can suggest acromegaly and should be investigated.
