Clinical diagnosis of congenital bilirubin metabolism abnormality requires physical examination, laboratory tests such as liver function, and liver biopsy if necessary.
1. Physical examination: In clinical physical examination, the general body is usually in good condition and there is no obvious digestive disorder. The liver may be enlarged and the spleen is usually not enlarged. There may be yellowing of the sclera and yellowing of the skin, which is a manifestation of jaundice.
2. Laboratory tests: liver function may be abnormal, and there is hyperbilirubinemia with obvious jaundice.
3. Liver biopsy: in order to make differential diagnosis, liver biopsy can be taken to do corresponding examination, which is usually normal and can exclude organic lesions of the liver.
The patient should consult the doctor in time to get a clear diagnosis and follow the doctor’s instructions for treatment.
