Yellow-green or green-brown skin

Bilirubin is an important basis for judging jaundice clinically and an important indicator of liver function. The skin and sclera are pale yellow to deep golden yellow is one of the main characteristics of the cause. The normal serum total bilirubin concentration is 1.7 ～ 17.1μmol / L, among which the bilirubin is lower than 3.4μmol / L for one minute. When the total bilirubin is 34 μmol / L, jaundice can be found clinically; if the serum total bilirubin exceeds the normal range and the jaundice is not visible to the naked eye, it is called recessive jaundice. Jaundice is most common in hepatobiliary diseases, but other Systemic diseases can also occur.
