The urinary mucus filament is a test that usually looks at the components of urine under a microscope, such as red blood cells, white blood cells, or crystals and mucus filaments, and normally there is a small amount of mucus filaments in human urine, especially in normal times, if you drink less water and urinate less, the urine will be concentrated and there will be more mucus filaments. Therefore, if all the items in the urine routine are normal, and there are no symptoms such as urinary urgency, frequent urination, bladder irritation, etc. are normal, if there are white blood cells or increased pus cells and a large number of mucus filaments, it may be considered to be due to urinary tract infection. Take medication according to the doctor’s advice and pay attention to local cleanliness and hygiene.
