The 5 key biomarkers that can tell you how well youre aging the mostcrucial is the most overlooked

You know your Social Security number, your ATM pin code, your mom’s phone number, but do you know your HbA1c?Five numerical biomarkers can reveal how well you’re aging and warn of trouble long before symptoms of disease appear, according to Dr.Florence Comite, founder of the Comite Center for Precision Medicine & Healthy Longevity.Comite — who wrote “Invincible: Defy Your Genetic Destiny to Live Better, Longer,” out April 28 — recommends starting to monitor these biomarkers between the ages of 25 and 30.“By the time symptoms send you to a doctor, the process has often been underway for quite some time, usually decades,” Comite told The Post.“If you want to be proactive to stop aging disorders rather than react to disease, you should establish your baseline early and track how your body changes over time.”Here’s everything you need to know about these five key biomarkers, including the one that Comite deems the “most crucial” among the bunch.A fasting glucose test measures blood sugar after an overnight fast to screen for prediabetes or diabetes.A normal fasting glucose for adults without diabetes is 70–99 milligrams per deciliter, while levels between 100–125 mg/dL indicate prediabetes and 126 mg/dL or higher suggests diabetes.“I like to see fasting glucose in a tighter, optimal range, based on research studies, 70s to 80,” Comite said.“Once you are consistently above 80, into the 90s or above, especially paired with elevated insulin, that is an early warning sign of impending prediabetes with insulin resistance.”“Fasting insulin is one of the most crucial — and most overlooked — biomarkers in medicine because it reveals how hard your body is working to stabilize your glucose,” Comite said.“This biomarker is rarely ordered by physicians, yet it is an early warning sign of insulin resistance and prediabetes, giving you a heads up about brewing metabolic issues decades �...
