One of albumin’s functions is to prevent water from leaking out of the blood and into your tissues. There are several schemes available to help determine the etiology of hyperbilirubinemia: Elevated direct bilirubin (conjugated hyperbilirubinemia) can be caused by several factors: Indirect elevated bilirubin (unconjugated hyperbilirubinemia) can be caused by several factors: Physicians will want to ask about the patient’s age, associated symptoms such as fever, weight loss or abdominal pain, a history of jaundice or abdominal surgery, social history to determine any risk factors for hepatitis (including alcohol consumption and risk factors). A different breakdown product, urobilin, is the main component of the straw-yellow color in urine. This hyperbilirubinemia is often caused by an underlying hematologic or hepatic disorder, but it can also be a benign finding. Main causes are when there's a blockage preventing bilirubin from moving into the intestines. In predominantly conjugated hyperbilirubinemia, liver enzymes should be obtained (aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transpeptidase and alkaline phosphatase), prothrombin time and albumin. Classification based on bilirubin processing based on location: Serologies for hepatitis or autoimmune disorders. Blockage of the bile ducts tends to increase the amount of direct more than in-direct bilirubin. The jaundice , or yellowing of the skin, sclera and mucous membranes for bilirubin typically is clinically detectable once serum bilirubin increases above 2.5 milligrams / deciliter (mg / dL) and is often detectable first conjunctiva or under the tongue. Bilirubin that reacts indirectly is calculated by subtracting the bilirubin score that reacts directly from the total bilirubin score. Bilirubin is a tetrapyrrole produced by the normal breakdown of heme. Use of medications including herbs / supplements and family history, since each of these can help diagnose the underlying etiology of hyperbilirubinemia.
