Primary | Difference in plasma phosphate in mmol/L at 5 specific times following a high-phosphate containing meal compared to a low-phosphate containing meal measured by analyzing of blood samples at each specific time. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Changes in plasma phosphate in mmol/L in blood samples at 5 specific times following a high-phosphate meal or low-phosphate meal compared to levels of plasma phosphate at preceding specific times and differences in these changes. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Difference in serum ionized calcium at 5 specific times following a high-phosphate containing meal compared to a low-phosphate containing meal measured by analyzing of blood samples at each specific time. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Changes in serum ionized calcium in blood samples at 5 specific times following a high-phosphate meal or low-phosphate meal compared to levels of serum ionized calcium at preceding specific times and differences in these changes. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Difference in plasma PTH at 5 specific times following a high-phosphate containing meal compared to a low-phosphate containing meal measured by analyzing of blood samples at each specific time. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Changes in plasma PTH in blood samples at 5 specific times following a high-phosphate meal or low-phosphate meal compared to levels of plasma PTH at preceding specific times and differences in these changes. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Difference in plasma FGF-23 at 5 specific times following a high-phosphate containing meal compared to a low-phosphate containing meal measured by analyzing of blood samples at each specific time. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Changes in plasma FGF-23 in blood samples at 5 specific times following a high-phosphate meal or low-phosphate meal compared to levels of plasma FGF-23 at preceding specific times and differences in these changes. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Difference in plasma magnesium at 5 specific times following a high-phosphate containing meal compared to a low-phosphate containing meal measured by analyzing of blood samples at each specific time. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
Secondary | Changes in plasma magnesium in blood samples at 5 specific times following a high-phosphate meal or low-phosphate meal compared to levels of plasma magnesium at preceding specific times and differences in these changes. | The specific times are: Before consumption of the meal(time 0), and 1 hour, 2 hours, 3 hours and 5 hours after consumption of the meal. | 5 hours | |
