Glucose can read normal for years while insulin creeps higher and higher, pumping out to keep blood sugar in range. You feel the effects as belly fat that will not shift, hunger one to two hours after eating, energy crashes in the afternoon, sugar cravings and sometimes brain fog. By the time fasting glucose rises, the process has typically been building for a decade. This test measures both markers at once and calculates HOMA-IR, the validated index of insulin resistance. A result above 2.0 is worth addressing. Above 2.5 is clinically significant. Pair with HbA1c for a complete metabolic baseline.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-ingredients\"\u003e\n\u003ch3\u003eWhat it measures\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eBiomarker\u003c\/th\u003e\n\u003cth\u003eSample\u003c\/th\u003e\n\u003cth\u003eReference Range\u003c\/th\u003e\n\u003cth\u003eWhat it tells you\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFasting Glucose\u003c\/td\u003e\n\u003ctd\u003eBlood (FlOx)\u003c\/td\u003e\n\u003ctd\u003e3.9 to 5.4 mmol\/L\u003c\/td\u003e\n\u003ctd\u003eMorning blood sugar after an overnight fast.
