IGF-1 above the age-adjusted range in someone with suggestive features is the screening result; confirmation comes from failure of growth hormone to suppress after oral glucose. During treatment, normalising IGF-1 is the target, and with pegvisomant it is the only usable measure because growth hormone itself rises. Pegvisomant monitoring is the clearest case of IGF-1 standing in for the hormone.
Reference ranges must be from the same assay and standardised, which the 2011 consensus addressed.
Low IGF-1 supports the diagnosis but normal IGF-1 does not exclude it, because other factors maintain hepatic production in some deficient adults. Children show a clearer relationship. During replacement, IGF-1 within the upper half of the normal range is the usual target, with the level used to adjust the amount of hormone given. Oral oestrogen in women lowers IGF-1 and confounds the measure.
IGFBP-3 and the acid-labile subunit are measured as supporting markers in children.
Because the marker is the readout in nearly every study on this site and a reader should know what it integrates and when it misleads. It describes clinical practice as reported; it describes no use of the pack.
