Routine urine usually requires 5-10 ml of urine to be fine. It is recommended that you should take the middle urine before taking the routine urine test. The middle urine is to urinate 5-10 ml first and then keep the middle urine so that the standard urine test results are true and reliable. The perineum and urethra should be cleaned effectively before retaining the urine routine to prevent bacterial infection in this area, which can lead to errors in the urine routine results. Urine routine needs to be checked for the presence of red blood cells, white blood cells, urine specific gravity, urine pH, urine bilirubin, urine bilirubin, urine ketone bodies, urine protein, etc. Be sure to leave 5-10 ml of urine, too little urine test results are prone to errors.
