| Pi2− (mg/dL) | 3.1 | 2.7–4.6 |
| Mg2+ (mg/dL) | 2.2 | 1.8–2.4 |
| Alkaline phosphatase (U/L) | 236 | 106–322 |

| PTH whole (pg/mL) | 44.8 | 8.3–38.7 |
| PTHrP (pmol/L) | < 1.0 | ≦1.1 |
| TSH (μIU/mL) | 0.49 | 0.54–4.26 |
| FT4 (ng/dL) | 0.93 | 0.76–1.65 |
| ACTH (pg/mL) | 32.1 | 7.2–63.3 |
| Cortisol (μg/dL) | 15.9 | 6.24–18.0 |
| Urine parameters | ||
| 24 h urinary Ca excretion (g) | 0.1 | 0.1–0.3 |
| 24 h urinary Pi excretion (g) | 0.58 | 0.5–1.0 |
| %TRP (%) | 89.9 | 80–94 |
| TmP/GFR (mg/dL) | 2.9 | 2.3–4.3 |
| Calcium creatinine clearance Ratio (CCCR) | 0.0059/0.0054 | > 0.01 |
TmP/GFR was estimated by nomogram for derivation of renal threshold phosphate concentration16. CCCR were calculated by plasma and 24-h urine samples for calcium and creatinine
