1 Normal values of direct bilirubin range from 0 to 0.4 mg/dL.  Total bilirubin (direct and indirect) range from about 0.2 to 1.2 mg/dL (some lab values range as high as 1.9 mg/dL). Medical literature sources have minor variations in normal levels).
Bilirubin is made when red blood cells break down as a result of normal cellular life cycle. After circulation, bilirubin goes to the liver. Bilirubin is excreted in the bile duct and is stored in the gall bladder. It helps digest fats and is excreted in the stool (http://www.healthline.com/health/bilirubin-blood#Overview1). Elevated bilirubin levels are found in hepatitis A. Hepatitis A is a disease of the liver caused by Hepatitis A virus. Symptoms include nausea, vomiting, diarrhea, fever, jaundice and abdominal pain (www.wikipedia.com). The goal of this study was to evaluate if there was a correlation between age (in years) and bilirubin level.
