A few days ago, he went to the hospital for examination, and the doctor asked him to have a urine test. Now let's take a look at the urine test.

What's the urine test for

First: urine routine examination in clinical is a preliminary examination can not be ignored, many early renal lesions can appear proteinuria or visible components in urinary sediment. Once abnormal urine is found, it is often the first indication of kidney or urinary tract disease, and also an important clue to the essence of pathological process. In recent years, many people emphasize that the doctor in charge should do routine urine examination by himself, which is a general diagnostic method for doctors to find kidney diseases. Urine routine examination includes color, transparency, pH, red blood cell, white blood cell, epithelial cell, tube type, protein, specific gravity and urine sugar.

Second: urine color: the color of normal urine, mainly caused by urinary pigment, its daily excretion is generally constant, so the depth of urine color changes with urine volume. Normal urine is straw yellow, abnormal urine color can be due to food, medicine, pigment, blood and other factors. Transparency: normal fresh urine, in addition to women's urine visible slightly turbid, most are clear and transparent, if placed too long, there will be mild turbidity, this is due to the pH change of urine, urine mucus protein, nuclear protein, etc.

Third: cells: the important cells in clinical urine are red blood cells, white blood cells and small round epithelial cells. red blood cell. Erythrocytes can be seen occasionally in the urine of normal people. After centrifugation, there are no more than 3 erythrocytes per high power field. If there is a large amount of red blood cells in the urine, it may be caused by renal hemorrhage, urinary tract hemorrhage, renal congestion and other reasons. Strenuous exercise and blood circulation disorders, can also lead to increased glomerular permeability, and in the urine protein and red blood cells.
