Diabetes Lab Values

Below is a question I recently received from

My fasting glucose number was 127. Does this sound like pre-diabetes or diabetes? What should I do to control by blood sugar?

A fasting blood sugar of 126 or greater is indicative of diabetes. However, be sure to get a second test from your PCP to confirm this diagnosis.

On a more interesting note, it is now accepted to use another lab value, hemoglobin A1c, to confirm a diagnosis of diabetes. Hemoglobin A1c (also known as glycosolated hemoglobin) is lab value that measures how well blood sugars were managed over a period of 3 months; it is also used by medical professionals to gauge how well diabetic patients have controlled their blood sugars. A hemoglobin A1c reading of 5.7-6.4% is indicative of pre-diabetes and a reading of 6.5% or higher confirms a diabetes diagnosis.

Whether you are in the pre-diabetes or diabetes stage, it is highly recommended that you meet with a certified diabetes educated and/or registered dietitian to help plan lifestyle interventions to keep you on the track to good health!
