Fasting Glucose

The Fasting Glucose Blood Test measures blood sugar after you have not eaten for at least 8 hours. High levels may be linked to diabetes, prediabetes, or insulin resistance, while normal levels show healthy blood sugar control and energy balance.

Fasting Glucose

Experiencing symptoms like excessive thirst or frequent urination, concerned about diabetes risk, or want to monitor your blood sugar control for metabolic health?

Overview

Think of the Fasting Glucose test as your body's energy meter – it measures how well your internal fuel system is working after you've been "running on empty" overnight. Just like checking your car's engine performance, this test reveals how efficiently your body manages blood sugar, which is your cells' primary fuel source. After fasting for 8-12 hours, your blood is tested to see how well your body maintains steady glucose levels without food coming in, giving doctors a clear picture of your metabolic health.

This simple blood test is incredibly valuable because it can catch problems before they become serious health issues. When your results are higher than normal, it might indicate pre-diabetes or diabetes – conditions where your body struggles to keep blood sugar in the healthy zone. This early warning system is especially important if you've been experiencing symptoms like constant thirst, frequent bathroom trips, or unexplained fatigue, or if you have risk factors like family history of diabetes or being over 45. By identifying these issues early, you and your healthcare provider can take steps to prevent or manage diabetes, protecting you from complications that affect your heart, nerves, and overall well-being.
