A clinic measures the blood glucose concentration of three patients to screen for diabetes. Table 1 shows the results of tests taken after fasting for 8 hours, and then 1 hour after consuming a high-carbohydrate meal. Patient X is healthy.
Table 1
| Patient | Blood glucose concentration (mmol/dm³) after fasting for 8 hours | Blood glucose concentration (mmol/dm³) 1 hour after meal |
|---|---|---|
| Patient X | 4.8 | 6.2 |
| Patient Y | 6.2 | 8.9 |
| Patient Z | 8.5 | 13.4 |
Compare the blood glucose concentration of Patient X with Patient Y after fasting for 8 hours.
