Home glucometers are inexpensive, easy to use and readily available. Not especially accurate. Will give you a general range of your blood glucose (eg., it IS 120 and definitely NOT 320). But small variations one reading to another is routine. Also, “real” blood glucose constantly fluctuates based on eating, exercise, metabolic state.Variations like you describe are meaningless

Glucometers test whole blood. Lab tests plasma. Plasma levels are more reliable and are the method on which the diagnostic criteria are based.
