About this test

This panel combines a calculated fasting insulin resistance index with measurements of random glucose, fasting insulin and fasting glucose-linked insulin. Together these markers are commonly used to help assess how well the body is managing blood sugar, which is relevant if you have risk factors such as a family history of diabetes, polycystic ovary syndrome, or difficulty losing weight.

With four biomarkers, this sits in the 86th percentile for clinical depth among the six similarly sized diabetes tests we track, and at £79 it is priced 59% below their £195 median. The main limitation is collection: you need to attend Inuvi Clinic in London for a venous draw, since the sample is not suitable for posting, though results come back quickly, within 2 days.

The overall score is strong across the board, with clinical depth and value for money standing out in particular. Collection convenience is the weakest area, reflecting the clinic-only requirement, but trust signals and results handling both score well, based on Medichecks' Trustpilot rating and the doctor review included with the result.

Who is it for?

This suits anyone with risk factors for insulin resistance, such as a family history of type 2 diabetes, polycystic ovary syndrome, or persistent difficulty losing weight, who wants a more detailed look than a single glucose reading provides.

We do not track a directly comparable competitor test for this exact four-marker combination, so we cannot point to a cheaper or deeper named alternative. If attending a clinic in London is not practical for you, be aware that this particular test has no home collection option.

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 the fasting insulin resistance index, random glucose, insulin and fasting insulin from the sample, and a doctor reviews the results as standard. Turnaround is 2 days.
