Bilirubin - Urine
Bilirubin is a product of the breakdown of haemoglobin from red blood cells. It is removed from the body via the liver, stored and concentrated in the gallbladder and secreted into the bowel. It is removed from your body through urine and faeces. Bilirubin causes the yellowish colour you sometimes see in bruises, due to red blood cells breaking down underneath the skin.
What might a high result mean?
Elevated levels of bilirubin can cause the skin and whites of eyes to become yellow (jaundice), as bilirubin builds up around the body. This is most likely caused by the liver being unable to remove sufficient bilirubin from the blood. This can be caused by liver damage such as cirrhosis, or, more commonly, a harmless inherited disorder called Gilbert's syndrome.
