In an investigation into metabolic clearance rates, the blood glucose concentrations of three canine subjects were measured after a 10-hour fast, and again 90 minutes after receiving an oral glucose load.
| Subject | Blood glucose concentration (mmol/dm3\text{mmol/dm}^3mmol/dm3) after fasting | Blood glucose concentration (mmol/dm3\text{mmol/dm}^3mmol/dm3) 90 minutes after glucose load |
|---|---|---|
| Subject X | 4.5 | 5.2 |
| Subject Y | 6.1 | 7.8 |
| Subject Z | 7.8 | 12.6 |
Compare the blood glucose concentration of Subject Y with the blood glucose concentration of Subject X after fasting.
