The analysis of bilirubin levels may aid the classification of anaemia and jaundice. Increased production (indirect/unconjugated) is seen with haemolysis.
Owing to the horse's unusual biliary excretion system, indirect (unconjugated) bilirubin levels can be high without clinical disease. This is usually associated with fasting.
Hepatic disease may lead to serum increases as a consequence of reduced hepatic uptake, reduced conjugation, or reduced excretion.
