High A1C Levels Without Diabetes: Is It Possible

A high A1C can reflect true dysglycemia, red-blood-cell changes, or an assay interference. The right next step is confirmation—not assuming that you do or do not have diabetes.

It is possible to have a high A1C without an established diabetes diagnosis. An A1C of 5.7% to 6.4% is in the prediabetes range. An A1C of 6.5% or higher meets a diabetes diagnostic threshold, […]

Prediabetes and Type 2 Diabetes: Why A1C, Fasting Glucose, OGTT, Kidney, and Lipid Testing Must Be Read Together

A connected testing guide to glucose diagnosis, kidney protection, cardiovascular risk, and meaningful follow-up.

Prediabetes and type 2 diabetes cannot be understood from one number alone. An A1C test estimates average glucose exposure over roughly two to three months. A fasting plasma glucose test measures one carefully timed point. […]

Diabetes and Prediabetes Blood Tests: A1C, Glucose, Insulin, and C-Peptide

Compare diabetes blood tests—including A1C, fasting glucose, OGTT, insulin, and C-peptide—for screening, diagnostic support, and ongoing monitoring.

Diabetes blood tests are not interchangeable. In nonpregnant adults, A1C, fasting plasma glucose, and the two-hour plasma glucose value from a 75-gram oral glucose tolerance test can be used for screening and diagnostic support. A […]

Obesity Is a Disease—And Lab Testing Can Reveal What the Scale Cannot

Why BMI and body weight cannot reveal the full impact of obesity—and how laboratory testing can uncover hidden metabolic and organ-related risks.

Doctors are reaching a clearer consensus: obesity is a complex chronic disease, but body weight and BMI alone cannot show how excess body fat is affecting an individual’s health. For decades, people living with obesity […]
