Hormones
IGF-1
Extended panel — run periodically
What it indicates
A growth factor produced mainly by the liver in response to growth hormone.
Why a series helps
It is fairly stable from week to week, so a change across several months stands out clearly.
What this page does not tell you
What a particular IGF-1 result means depends on you: your history, your medication, why the test was taken. Ziro does not interpret results for individuals and does not diagnose. If something in your results warrants a conversation, that conversation is with a doctor, and your results are downloadable so you can bring them.
