Uric acid crystals

Uric acid crystals resemble fine red sand fine particles under visual observation, and they are often deposited on the bottom of urine containers. Under the microscope, yellow, dark brown red diamond, triangular, rectangular, oblique square crystals can be seen, which can be dissolved in sodium ammonium oxide solution. Uric acid is the end product of purine metabolism in the nucleoprotein of the body. It is usually excreted in the urine in the form of uric acid or ammonium urate, calcium urate, sodium urate salts. Normally, eating more animal purities containing high purine can make urine Uric acid increases, but in acute gout, acute fever in children, chronic interstitial nephritis, and leukemia, due to the large number of cell nuclei breakdown, it can also excrete uric acid. Hyperuricemia is also seen when renal tubules have difficulty reabsorbing uric acid.
