Unconjugated bilirubin of 20.8 μmol/L and total bilirubin of 26.2 μmol/L are out of the normal range and are considered to be high; a single high value is not a cause for concern, but multiple high values require treatment. Bilirubin metabolism test is one of the laboratory tests for liver disease. It includes the measurement of serum total bilirubin, conjugated bilirubin and unconjugated bilirubin. The normal values of serum total bilirubin (STB) are 3.4-17.1 μmol/L; the normal values of conjugated bilirubin (CB) are 0-6.8 μmol/L; the normal values of unconjugated bilirubin (UCB) are 1.7-10.2 μmol/L. If the value is high only once in a while, it may be related to staying up late, drinking alcohol, smoking and other factors, there is no need to worry about it yet, but it is necessary to repeat the test on another day. If the value is still high, it is necessary to consider jaundice, hepatitis and other related diseases, and it is recommended to go to the relevant department for standardized treatment under the guidance of a doctor.
