What is the normal range for random blood glucose?

Random blood glucose can vary a lot because it’s measured at any time, including after meals. In healthy individuals, it tends to be around fasting levels near 4 mmol/L and can rise after eating, typically staying below about 8 mmol/L for most people two hours postprandially. So a practical normal range for a random glucose test is roughly 4 to 8 mmol/L (about 72 to 144 mg/dL). Values consistently higher, especially above 11–12 mmol/L, suggest possible hyperglycemia or diabetes, while very low values (below about 4 mmol/L) can indicate hypoglycemia.
