If a patient’s urinary routine suggests that the patient’s urine bilirubin is (+), for most people, this is mostly considered and the patient usually drinks less water, causing the urine to concentrate after the formation of the patient’s urine bilirubin (+) number. At this time, it is recommended that patients can actively consider drinking more water and urinating more, and the patient’s urine bilirubin can mostly be reduced to normal. In addition, after drinking water and urinating, patients should pay attention to regular rechecking to see if the bilirubin in their urine routine is reduced to normal. For some patients, if the urine bilirubin is (+) in two consecutive retests, the patient needs to have a blood test for liver function. The patient needs to have further blood tests for liver function and an ultrasound of the upper abdomen to determine whether the patient has liver function impairment. If the patient has elevated bilirubin and elevated glutamic acid and glutamic oxalacetic aminotransferase, the patient is considered to have liver function damage, hepatocellular necrosis, and intrahepatic cholestasis, which may also cause elevated urinary bilirubin. If the urine bilirubin is (+) due to liver disease, it is necessary to actively consider treating the primary liver disease and to give active liver protection treatment.
