To assist with control of blood glucose levels, the American Diabetes Association (ADA) has recommended glycated hemoglobin testing (HbA1c) twice a year for patients with stable glycemia, and quarterly for patients with poor glucose control. Interpretative ranges are based on ADA guidelines.
- Glucose Your blood sugar level at the time of the test — a core marker for diagnosing and monitoring diabetes and metabolic health.
- Hemoglobin A1c (HbA1c) Reflects your average blood sugar over the past 2-3 months, based on how much sugar has attached to your hemoglobin. Key marker for diabetes diagnosis and monitoring.
- Total Cholesterol The combined measure of all cholesterol in your blood — HDL, LDL, and other lipoproteins together. A foundational marker of cardiovascular risk.
- Triglycerides A type of fat in your blood used for energy storage. Elevated levels are linked to increased cardiovascular risk and often reflect diet, weight, or metabolic health.
- HDL Cholesterol The 'good' cholesterol that helps remove excess cholesterol from your bloodstream. Higher levels are generally linked to lower cardiovascular risk.
- LDL Cholesterol, Calculated The 'bad' cholesterol that can build up in artery walls. A core marker used to assess cardiovascular disease risk.
- Non-HDL Cholesterol Total cholesterol minus HDL — capturing all the potentially artery-clogging ('bad') cholesterol particles in one number.
- Total Cholesterol / HDL Ratio Compares your total cholesterol to your HDL ('good') cholesterol, offering a quick snapshot of cardiovascular risk balance.
