Ammonium acid urate (ammonium biurate) crystals in urine sediment: microscopic appearance at pH 5, morphology, and nomenclature specifics.
🔬 Urine of an 11-year-old child, Ammonium acid urate. pH=5, magnification x400+zoom. ✅ In foreign sources, the incorrect name ammonium biurate has become established. ✅ This salt contains only one uric acid residue.
