About this test

This test measures IGF-1, a marker of growth hormone activity that plays a role in muscle growth, metabolism and overall development. It is a single biomarker, so it gives one data point rather than a wider hormone picture.

At £149, this test is priced 139% above the £62.25 median for the 20 similarly sized hormone tests we track, the biggest such gap among the Medichecks tests covered in this fact sheet. Clinical depth is around the middle of the pack for hormone tests in general, in the 45th percentile. Collection also requires a venous draw at the Inuvi Clinic in London, since the sample cannot be posted, and results take 5 days.

The overall score is held back mainly by value for money and collection convenience, the two lowest-scoring criteria here. Trust signals still score well, based on Medichecks' Trustpilot rating and doctor review included with every test, but on price and convenience this is one of the weaker tests in the range we cover for this provider.

Who is it for?

This suits people who specifically want to check IGF-1 as a growth hormone marker, most likely on a doctor's advice, and who are able to attend the Inuvi Clinic in London for a venous draw.

Because this test is priced well above the median for similarly sized hormone tests in our data, it may be worth asking a GP whether the same marker can be arranged another way before booking directly.

How it works

You need to visit the Inuvi Clinic in London for a venous blood draw, as the sample is not suitable for posting. The lab measures IGF-1 from the sample, and a doctor reviews the result as standard. Turnaround is 5 days from when the sample reaches the lab.
