TyG-BMI Index, Calculated: One Read on Fuel Handling and Body Size
The TyG‑BMI is a calculated biomarker that combines two routine blood measures—triglycerides and glucose—with a measure of body size, BMI. Triglycerides are fat particles carried in the bloodstream, built from dietary fat and liver production (triglycerides). Glucose is the main sugar fuel released from digestion and the liver (glucose). Available at 2,000+ lab locations and at-home (select states). See FAQs below
Measuring Insulin: What Your Result Signals About Early Resistance
Insulin blood testing measures the hormone insulin circulating in your bloodstream. Insulin is made by beta cells in the pancreas (pancreatic islet β‑cells). It is produced from a larger precursor (proinsulin) and released together with its companion fragment (C‑peptide). Available at 2,000+ lab locations and at-home (select states). See FAQs below
Reading Your HbA1c: How Sugar-Coated Hemoglobin Tracks Months of Glucose
Hemoglobin A1c is hemoglobin with sugar attached. Inside red blood cells, glucose in the bloodstream slowly sticks to hemoglobin A, forming a stable sugar–hemoglobin adduct (non-enzymatic glycation of the beta-chain N-terminal valine, yielding a ketoamine called HbA1c). This happens continuously and irreversibly for as long as the red cell circulates. Available at 2,000+ lab locations and at-home (select states). See FAQs below
Reading Your Glucose Result: The Body's Real-Time Energy Currency
Blood glucose testing measures the amount of glucose—the simple sugar circulating in your bloodstream. Glucose originates from digestion of dietary carbohydrates in the small intestine and from the liver, which releases stored glucose (glycogenolysis) and creates new glucose from non‑carbohydrate sources (gluconeogenesis). Available at 2,000+ lab locations and at-home (select states). See FAQs below
Measuring Fructosamine: A Two-to-Three-Week Window on Average Blood Sugar
Fructosamine is the collective signal of sugars attached to blood proteins. In the bloodstream, glucose binds spontaneously to free amino groups on circulating proteins—mostly albumin—through nonenzymatic glycation (Maillard reaction), forming stable ketoamine adducts (fructosamines). A fructosamine blood test quantifies these glycated serum proteins, so the biomarker originates from the everyday interaction between glucose and the body’s protein pool in serum. Available at 2,000+ lab locations and at-home (select states). See FAQs below
Measuring the Glycation Gap: What the Glucose/HbA1c Ratio Reveals
Estimated glucose / HbA1c ratio (Glycation gap) blood testing compares your hemoglobin A1c with an independent estimate of your average blood glucose. Hemoglobin A1c (HbA1c) forms when glucose nonenzymatically attaches to hemoglobin inside red blood cells (erythrocytes) over their lifespan. Available at 2,000+ lab locations and at-home (select states). See FAQs below
Reading Your eAG Result: A1c Translated Into an Everyday Number
Estimated average glucose is a calculation that translates your long-term blood sugar pattern into a single everyday number. It is derived from hemoglobin A1c, the fraction of hemoglobin in red blood cells that becomes coated with sugar. Glucose circulating in your blood drifts into red blood cells and sticks to hemoglobin over time (non-enzymatic glycation). Available at 2,000+ lab locations and at-home (select states). See FAQs below
Reading Your Cardio IQ Insulin Resistance Score: A Lipoprotein-Based Signal
Cardio IQ Insulin Resistance blood testing is a cardiometabolic panel that estimates how resistant your body is to insulin (insulin resistance). It measures insulin produced by pancreatic beta cells alongside select metabolic signals released into the bloodstream by the liver, fat tissue, and circulating lipoproteins, then brings them together into a coherent picture of insulin action. Available at 2,000+ lab locations and at-home (select states). See FAQs below
Reading Your TyG Index: A Calculated Proxy for How You Respond to Insulin
The Triglyceride–Glucose index (TyG index) is a calculated number derived from two routine fasting blood measurements: triglycerides and glucose. Triglycerides are the body’s transport form of fat, carried in the bloodstream within lipoprotein particles (mainly VLDL from the liver). Glucose is the primary circulating sugar used by cells for energy. Available at 2,000+ lab locations and at-home (select states). See FAQs below
