Bilirubin is a substance that can be found in the blood that is the result product of red blood cell disintegration. Red blood cells will disintegrate, navigate through the liver, then travel through the gallbladder and digestive tract, where it is then finally eliminated. When levels of bilirubin are elevated, the condition is called hyperbilirubinemia. High bilirubin levels can be indicative of numerous problems going on with the liver or gallbladder, and can also point to hemolysis, or a higher then normal destruction rate of the red blood cells.
Information. A normal level of bilirubin in the blood would land somewhere within the range of 0.3 to 1.2 mg/dL or milligrams per deciliter. Any numerical value that lands above 1.2 mg/dL is going to be concluded as elevated or high. Often times other symptoms associated with high bilirubin levels such as fatigue, vomiting, chills, chest pain, nausea, dark urine, abdominal swelling, fever, and weakness, can help a physician identify the underlying cause of the elevated bilirubin levels in the blood. A common indication of high bilirubin levels is jaundice, where the skin and white of the eyes have a noticeable yellowish tint to them.
