If there are more than 5 white blood cells in each high-power field, it is called pyuria under the microscope. Microscopic pyuria suggests purulent inflammation of urethra, such as pyelonephritis, bladder or urethritis and renal tuberculosis. When glomerulonephritis occurs, white blood cells in urine can also increase slightly.

leading indicators
1, red blood cell count and hemoglobin determination (HGB)
The first item in the routine blood test list is the examination of red blood cell count. The main function of red blood cells is to deliver oxygen to all tissues and organs of the whole body and excrete carbon dioxide produced in the body. This function mainly depends on hemoglobin (Hb), a kind of protein in red blood cells.
2. White blood cell count (WBC) and white blood cell classification count (DC)
White blood cells in blood include neutrophils, eosinophils, basophils and lymphocytes. The white blood cell count (WBC) in the laboratory sheet refers to the determination of the total number of white blood cells in the blood, and the classified count refers to the percentage of various white blood cells.
3. Platelet count
Coagulation is the main function of platelets. Without it, a small wound may be life-threatening. Generally speaking, the count of platelets is the third key point that should be paid attention to when observing the test sheet. If there is thrombocytopenia, there may be something wrong with coagulation.
