Clinical urineanalysis

Urinalysis (urinalysis) is a laboratory test that allows evaluating physical and chemical characteristics of the urine and microscopy of the sediment.

What indicators are examined in the clinical urine analysis?

The features that are examined are the color of urine, its transparency, specific gravity, acidity (pH). The urine is examined on the concentration of protein, glucose, bilirubin, urobilinogen, ketones, nitrite and hemoglobin. Epithelial cells, erythrocytes, leukocytes, cylinders, bacteria are also detected in the urinary sediment.

Why is urinalysis performed?

  • for the diagnosis of kidney diseases: nephritis, nephrosclerosis, amyloidosis, kidney stones, tumors;
