Glucose Testing: Is Your Blood Sugar in the "Sweet Spot"?

Find out if you have optimal glucose levels

Glucose, a type of sugar, is your body's primary energy source. The hormone insulin helps move it from your bloodstream into your cells. Without a lab test to determine what your levels are, you may be blissfully unaware of the potential for serious health risks, including diabetes, heart disease, stroke, kidney disease, and more.

What does a blood glucose lab test check for?

  • Evaluates the glucose levels in your blood
  • Estimates blood sugar levels over a given period of time
  • Fasting may be required, depending upon the test

Measures fasting insulin levels to help identify resistance

5 (6)
  • $29.90
  • $22.43
  • Save $7.47

Fasting insulin levels may be elevated in people with insulin resistance and type 2 diabetes, but they may be abnormally low for those with type 1 diabetes or advanced type 2 diabetes. This blood test measures fasting insulin to help diagnose insulin resistance and type 2 diabetes.
