Urine bilirubin 1 +, may not be normal, need to be combined with other test results to determine the specific analysis.
Urinary bilirubin is a metabolic product of red blood cell destruction, and normally it should be negative. Urinary bilirubin 1+ indicates that the test result is positive, which is abnormal. When the patient has hepatocellular damage or intra- or extra-hepatic cholestasis, bile duct obstruction and other diseases, it will lead to abnormally high plasma-conjugated bilirubin, and the urine bilirubin will also be positive.
When urine bilirubin test is performed, if the urine specimen is left for too long or there are some special substances mixed in the urine, it can lead to false-negative or false-positive test results.
If urine bilirubin is found to be positive, you should go to the hospital in time for liver function tests to clarify whether there is any liver function abnormality and elevated blood bilirubin. If the blood bilirubin is elevated, it is necessary to further improve the relevant examination to clarify the cause of the disease.
