What is the normal range for blood glucose in mg/dL as measured by a glucometer?

• A. 60-100 mg/dL
• B. 100-140 mg/dL
• C. 80-120 mg/dL
• D. 70-110 mg/dL

Answer: (C)

Glucometer readings in a healthy person typically stay within a narrow range around baseline, about 80 to 120 mg/dL. This window captures the normal everyday fluctuations you’d see from fasting to shortly after eating, without dipping into low blood sugar or climbing into higher levels that suggest hyperglycemia. Values a bit lower, around 60–100, can indicate hypoglycemia at times, and readings around 100–140 mg/dL are higher than what’s usually seen as a normal baseline for most non-diabetic individuals. The 80–120 range is a practical standard you’ll encounter as a target for a normal, non-diabetic reading, reflecting the common balance of fasting and post-meal values. Remember that timing matters: fasting glucose is often about 70–99 mg/dL, and after meals, readings can rise but should stay within a healthy range for the individual.
