Fasting insulin is the lab my functional medicine doctor cares about most for glycaemic control: it's a much earlier marker of metabolic dysfunction than glucose or A1C.
My fasting insulin: 29 → 13 → 6 uIU/mL over 9 months. Target is <7. By the time your fasting glucose is elevated, your insulin has been elevated for YEARS trying to compensate.
Ask your doctor to include fasting insulin in your bloodwork panel. It's cheap (~$20) and incredibly informative.
A narrower follow-up, since the general answer is now clear:
Was that from a primary source or from a summary of one?

My labs after 12 months on glycaemic control: A1C 5.3%, fasting glucose 78 mg/dL, fasting insulin 7 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 7.1% and fasting glucose was 113 mg/dL. The improvement has been dramatic and consistent.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 119 | 101 | 95 | 85 |
| Insulin (fasting) | 25 | 15 | 11 | 5 |
| HOMA-IR | 5.5 | 4.0 | 2.3 | 1.3 |
| Uric Acid | 8.7 | 6.9 | 6.2 | 5.0 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 5.5 to near 1.0 is a metabolic transformation.

PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 12 months: periods became regular for the first time in ever, testosterone levels normalized, acne cleared significantly, and — unexpectedly — my hormonal symptoms have almost completely resolved.
GLP-1 agonists address the insulin resistance at the root of PCOS. For PCOS patients, this isn't "just" a weight loss drug — it's treating our underlying metabolic dysfunction.
