Bilirubin is an orange-yellow pigment that occurs naturally in your blood. It forms after your red blood cells break down and is sent through your gallbladder, bile ducts, and liver. Your liver helps excrete it by changing its chemical make-up so that most of it can pass through your stool as bile.
But what happens when you have low levels of bilirubin? Is it a cause for concern? In this article, we take a closer look at what is considered low bilirubin levels, the causes, and the symptoms you should be on the lookout for. Here’s everything you should know…
Types of Bilirubin
If you require a bilirubin test you should know there may be a few kinds of bilirubin that show up on the test. First, unconjugated (indirect) bilirubin happens when hemoglobin from red blood cells is broken down and bound to a protein in the blood called albumin. It’s then sent to the liver.
Next is conjugated (direct) bilirubin which happens when bilirubin fastens to glucuronic acid in the liver before it is passed out of the body. The final type is total bilirubin which refers to all bilirubin in your bloodstream.
