The table below shows the blood glucose concentrations of three patients after fasting for 12 hours, and then two hours after consuming a carbohydrate-rich test meal.
| Patient | Blood glucose concentration (mmol/dm³) after fasting | Blood glucose concentration (mmol/dm³) 2 hours after a meal |
|---|---|---|
| Patient A | 4.8 | 5.9 |
| Patient B | 5.2 | 8.1 |
| Patient C | 7.1 | 11.5 |
Compare the blood glucose concentration of Patient A with the blood glucose concentration of Patient B after fasting.
