On the surface, this chart makes sense and seems pretty clear cut. Let’s step through the process by reviewing a few examples and learn to read between the lines.
Susan has a fasting glucose of 85 mg/dL, which is in normal range. Two hours after breakfast, her glucose increased to 135 mg/dL. Her post meal glucose is also within range of less than 140 mg/dL.
Barry has a fasting glucose of 100 mg/dL. Two hours after breakfast, his glucose increased to 150 mg/dL. Both readings are slightly out of range.
