Plain-English guides to the growth & recovery markers we measure and what your results mean, written to inform the conversation with your practitioner.

Markers in this group

IGF-1 (Insulin-like Growth Factor 1)IGF-1 is a hormone that carries the day-to-day signal of your growth hormone — the liver makes it whenever growth hormone is active. Because its level stays steady through the day, while growth hormone itself spikes and dips, it is a handy mirror of your average growth-hormone activity. It is read against an age-matched range, since levels fall naturally as we get older.

Possible reasons:

This can relate to sleep, stress, nutrition, or timing of the test.

Next steps: Discuss with your GP. Age and assay method affect interpretation.

in range

Your growth and recovery markers are in the expected range, supporting healthy tissue repair and regeneration.

Possible reasons:

Consistent sleep and nutrition often support in-range results.

Next steps: No follow-up is usually needed.

a little high

Higher growth marker levels can vary for many reasons. IGF-1 varies with age and assay method.

Possible reasons:

This can relate to timing of the test, recent exercise, or individual variation.

Next steps: Discuss with your GP. They can determine if any follow-up investigation would be appropriate.
