Indirect bilirubin of 46 μmol/L is a more serious condition if it is caused by pathologic factors.
Indirect bilirubin refers to bilirubin that is not bound to glucuronic acid in the liver, also called unconjugated bilirubin, which is an indicator reflecting the metabolic function of the liver and the decomposition of erythrocytes, with a normal reference value of 0-12 μmol/L. It is mainly used for identification and diagnosis of jaundice (including hemolytic jaundice, hepatocellular jaundice, etc.).
Under normal circumstances, indirect bilirubin may be elevated after meals and in newborns. Pathological conditions such as acute and chronic hepatitis, cirrhosis, hemoglobinopathies, and anemia may also cause elevated indirect bilirubin. Indirect bilirubin of 46 μmol/L is a more serious condition if it is caused by pathologic factors.
Indirect bilirubin is usually measured in the morning on an empty stomach. It is important to note that different hospitals use different testing methods and the values may vary, depending on the reference value given in the test report.
If the indirect bilirubin is 46 μmol/L, it is recommended to consult a doctor for diagnosis and evaluation of the condition.
