Most glucometers use whole blood to monitor blood glucose levels. Lab equipment uses the plasma of the blood to monitor blood glucose levels. Lab testing does not consider red blood cells for monitoring blood glucose. Thus, you get the different readings of blood glucose monitoring due to the different types of blood samples. Blood glucometers generally have up to 20% error accuracy. Heat, humidity, and low temperature also affect the readings on glucometers so, you may get different results.
