summary
If you measure 4.6mmol/L before meals, it is healthy blood sugar, and if you measure 4.6mmol/L after meals, it is mild hypoglycemia.
If 12.8mmol/L is measured before meals, diabetes can be highly suspected.
We must pay close attention to further examination of glucose tolerance and glycosylated hemoglobin to diagnose or exclude it; If 12.8mmol/L is measured after meals, diabetes can also be suspected and further examination is needed.
