what is a normal non fasting glucose reading
Random glucose test The reference values for a "normal" random glucose test in an average adult are 79–160 mg/dl (4.4–7.8 mmol/l), between 160–200 mg/dl is considered pre-diabetes, and > 200 mg/dl is considered diabetes according to ADA guidelines (you should visit your doctor or a clinic for additional tests however as a random glucose of > 200 mg/dl does not necessarily mean you are diabetic).[citation needed]
Glucose Glucose is a simple sugar with the molecular formula C6H12O6. Glucose circulates in the blood of animals as blood sugar. It is made during photosynthesis from water and carbon dioxide, using energy from sunlight. It is the most important source of energy for cellular respiration. Glucose is stored as a polymer, in plants as starch and in animals as glycogen.
