Function Health: The Case for Testing Insulin Before You Need To

Standard metabolic panels test glucose. Function Health tests glucose and insulin together — and that distinction catches metabolic dysfunction years before a glucose reading becomes abnormal.

The Gap in Standard Preventive Care

Most primary care physicians order a basic metabolic panel annually: glucose, creatinine, electrolytes, liver enzymes. What they don’t routinely order is insulin. Testing fasting insulin alongside glucose reveals insulin resistance — the metabolic precondition behind type 2 diabetes, cardiovascular disease, and nonalcoholic fatty liver — long before glucose levels tip into the prediabetic range. Function Health’s panel of more than 160 lab tests is built on the premise that the gap between what standard care orders and what preventive medicine actually requires is substantial, and worth paying to close.

Beyond metabolic markers, the platform includes hormonal testing: cortisol, thyroid hormone fractions (not just TSH), leptin, and sex hormones. These markers interact in ways that standard care panels don’t capture — a suppressed thyroid with normal TSH, for instance, or elevated cortisol driving insulin resistance in someone whose glucose appears normal. Function Health’s framing connects specific lifestyle factors — seasonal vitamin D variation, time outdoors, sleep consistency — to the corresponding lab markers, making the data interpretable rather than just comprehensive.

What the Platform Actually Offers

Function Health is a membership service, not a one-time lab order. Members receive longitudinal tracking: the same panel repeated over time, with trends surfaced alongside reference ranges. Optional imaging — MRI and CT scans — is available as a diagnostic add-on for members wanting structural screening beyond biomarkers.

The clinical advisors behind the platform include Dr. Mark Hyman, whose functional medicine framework prioritizes upstream metabolic markers over reactive symptom treatment. The platform’s communications are consistently labeled as health data rather than medical advice — appropriate for a service that provides information but leaves clinical interpretation to qualified physicians.

Compared to platforms like Hone Health or DEXA-focused longevity services, Function Health sits at the diagnostic layer rather than the intervention layer. It tells you what your numbers are across an unusually broad set of markers; it does not prescribe treatment. That boundary is appropriate for most users and makes the platform complementary to, rather than a replacement for, clinical care.
