Urine pH, red blood cells, white blood cells, transparency, color, epithelial cells, proportion of protein, urine sugar and other related indicators can be known through routine urine examination. Routine urine examination is a common examination, which also plays an important role in the diagnosis of urinary tract stones, biliary obstruction, urinary tract infection, chronic nephritis, kidney disease, diabetes and other diseases. Under normal circumstances, the urine is light yellow and transparent. If the red blood cells in the urine are elevated, it does not rule out that there are hemorrhagic diseases in the urinary tract. If the white blood cells are elevated, it indicates that there are infectious diseases in the urinary tract. If the patient has pathological proteinuria, it is usually related to diseases such as pyelonephritis and glomerulonephritis.
