Inorganic phosphates (Pi) [S/P/U24h]
Reference range, target level, or decision threshold
0.9-1.6 mmol/L (2.8-5.0 mg/dL)
15-30 mmol/24 h (466-931 mg/24 h)
[mmol/L] × 3.1 = [mg/dL]
[1 mmol = 31 mg]
Interpretation of results
↑ Renal failure, hypoparathyroidism (↓ Pi in urine), pseudohypoparathyroidism
↓ Primary hyperparathyroidism (↑ Pi in urine)
