Adiponectin
Adiponectin blood testing measures the level of adiponectin circulating in your blood. Adiponectin is a hormone-like protein (adipokine) made primarily by fat tissue (adipose tissue) and secreted by individual fat cells (adipocytes) into the bloodstream. At home blood testing is available in select states. See FAQs below
Cardio IQ Insulin Resistance
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. At home blood testing is available in select states. See FAQs below
Corrected Calcium (Albumin-adjusted)
Corrected calcium (albumin‑adjusted calcium) is a calculated estimate that modifies your routine blood calcium to account for albumin, the main protein that carries calcium in the bloodstream. In blood, calcium exists in two forms: attached to proteins, chiefly albumin (protein‑bound), and unbound (ionized). At home blood testing is available in select states. See FAQs below
Estimated Average Glucose (mg/dL)
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). At home blood testing is available in select states. See FAQs below
Estimated Average Glucose (mmol/L)
Estimated Average Glucose (eAG) is a calculated value that translates hemoglobin A1c into an everyday blood sugar number. It arises from the way glucose in the bloodstream binds slowly and steadily to the hemoglobin protein inside red blood cells (erythrocytes). This attachment happens without enzymes (nonenzymatic glycation). At home blood testing is available in select states. See FAQs below
Estimated Glucose / HbA1c Ratio (Glycation Gap)
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. At home blood testing is available in select states. See FAQs below
Fructosamine
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. At home blood testing is available in select states. See FAQs below
Glucose
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). At home blood testing is available in select states. See FAQs below
Hemoglobin A1c (HbA1c)
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. At home blood testing is available in select states. See FAQs below
Insulin
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). At home blood testing is available in select states. See FAQs below
Leptin
Leptin blood testing measures the amount of leptin in your bloodstream. Leptin is a hormone made mainly by body fat (white adipose tissue) and released by fat cells (adipocytes) in proportion to stored energy. It is one of the key signaling proteins produced by fat (adipokine) and is encoded by the LEP gene. At home blood testing is available in select states. See FAQs below
(Triglyceride - Glucose Index) - TyG Index
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. At home blood testing is available in select states. See FAQs below
TyG-BMI Index
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). At home blood testing is available in select states. See FAQs below
Uric Acid
Uric acid blood testing measures urate, the end product of purine breakdown. Purines come from the nucleic acids in your cells and from food. As cells turn over and purines are recycled or degraded, enzymes convert them through hypoxanthine and xanthine to uric acid (urate), mainly via xanthine oxidase in the liver and intestinal tissues. At home blood testing is available in select states. See FAQs below
