Glucose, Plasma

This test measures the amount of glucose, or sugar, in the liquid part of your blood. It helps show how well your body manages energy, which is important if you have symptoms like excessive thirst, fatigue, or fainting. Doctors use this information to screen for diabetes or to identify low blood sugar levels. However, a single result cannot diagnose a specific medical condition or determine the cause of irregular levels without additional testing.
