Link to Article | |
In each type of jaundice, will bilirubinuria be detected?
|
Haemolytic NO - because most of bilirubin is unconjugated Obstructive YES - because conjugated bilirubin accumulates Hepatocellular NO - because bilirubin fails to conjugate due to liver cell damage NB - the kidney can only excrete the water soluble conjugate |
