Click here to contact me with questions about your laboratory results - I do not volley e-mails back and forth because it is just too time consuming to keep track of who is responding to what e-mail. If you have a health question, please read about Signs and Symptoms before our conversation.

This is a brief summary of lab value interpretation and is not intended in any way to be comprehensive or replace any conversation of your results with your doctor.

This is a measure of the sugar level in your blood. High values are associated with eating before the test, and diabetes.

The normal range for a fasting glucose is 70 - 110 mg/dL. According the the 1999 ADA criteria, diabetes is diagnosed with a *fasting* plasma glucose of 126 or more. A precursor, Impaired Fasting Glucose (IFG) is defined as reading of fasting glucose levels of 110 - 125. Sometimes a glucose tolerance test, which involves giving you a sugary drink followed by several blood glucose tests, is necessary to properly sort out normal from IFG from diabetes.

Be aware that variations in lab normals exist. Also, Europeans tend to use a 2 hour after eating definition of diabetes rather than a fasting glucose. Using the European standards tends to increase the number of people who are classified as having diabetes.
