| Amorphous Urates Amorphous urates appear as dark or yellow red granules while phosphates are white or colorless. The pH of the urine determines the type of amorphous crystals present. They may be urates in acid urine or phosphates in alkaline urine. | View Page |
| Crystals in Normal Alkaline Urine Crystals found in normal alkaline urine include triple phosphate, ammonium biurate, calcium carbonate, amorphous phosphates, and calcium oxalate. This slide shows an example of triple phosphate crystals. These may appear as four to six sided prisms resembling coffin lids. They indicate either stasis of the bladder or a stale sample. | View Page |
| Please identify these crystals occurring in acid urine. | View Page |
| Amorphous Urates Amorphous urates can be dissolved in dilute sodium hydroxide. Amorphous phosphates will dissolve in dilute acetic acid. In either case, the bacteria will remain. | View Page |
