| Used in the investigation of calcium and/or phosphate metabolism. Hypoparathyroidism, vitamin D intoxication and renal failure with decreased glomerular phosphate filtration give rise to hyperphosphataemia. Hypophosphataemia occurs in rickets, hyperparathyroidism and Fanconis syndrome. | |
| Phospholipids contained in liposomal drug formulations (e.g. AmBisome) may be hydrolysed in the test due to the acidic reaction pH and thus lead to elevated phosphate results. | |
