Uric acid is a breakdown product of purine compounds that is excreted in the urine. The average daily uric acid excretion is normally 150-250g. Uric acid poorly dissolves in water and can crystallize in the kidneys, leading to kidney stones.
A urine test can also shed light on kidney function diseases and a number of internal medicine problems. Analysis of urine samples can detect urinary tract infections, but the result can also indicate the presence of diabetes or inflammation in the body.
In the urine sediment, 1-3 red blood cells are normally visible in the field of view, in case of a higher number, we talk about blood urination.
It is called pyuria if more than 4-6 white blood cells can be seen in the sediment.
If hyaline, white blood cells, and red blood cells are also visible (imprints of tubules from the kidneys), we are talking about cylinder emptying.
