What is the difference between Conjugated and Unconjugated Bilirubin? • Unconjugated bilirubin is water insoluble while conjugated bilirubin is water-soluble. • Unconjugated bilirubin forms in the reticuloendothelial cells while liver forms conjugated bilirubin. • Conjugated bilirubin enters the small intestine with bile while unconjugated bilirubin doesn’t. Read more: 1. The conjugated bilirubin is present in bile, while the unconjugated bilirubin is not present in bile. The conjugated bilirubin is normally not present in urine, but appears in high plasma concentrations. The unconjugated bilirubin is not present in urine. The conjugated bilirubin is not toxic to the tissues. The unconjugated bilirubin is toxic to the tissues. The accumulation of unconjugated bilirubin in the brain leads to kernicterus (neurologic damage). The lab reports the total bilirubin, and also the percent that is conjugated vs. unconjugated. If you have a lot of bilirubin around and it is mostly unconjugated, that means that it hasn’t been through the liver yet – so either you’ve got a situation where you’e got a ton of heme being broken down (and it’s exceeding the pace of liver conjugation), or there’s something wrong with This form of bilirubin travels from the bloodstream to the liver. This molecule is not water soluble. Conjugated (Direct): Bilirubin is converted from unconjugated to conjugated bilirubin in the liver. This happens when sugar attaches to the unconjugated bilirubin. The unconjugated bilirubin turns into bile and enters the small intestines. It is eventually eliminated through a person's stool. This molecule is water soluble. The proportion of conjugated bilirubin with respect to the total raised bilirubin can give a clue as to cause of jaundice. 20-40% of total: more suggestive of hepatic than posthepatic jaundice. 40-60% of total: occurs in either hepatic or posthepatic causes > 50% of total: more suggestive of posthepatic than hepatic jaundice . Note that if conjugated bilirubin is less than 20% of total then For those under 18, the normal level will be will be 1 mg/dl. Normal results for conjugated (direct) bilirubin should be less than 0.3 mg/dl. Men tend to have slightly higher bilirubin levels than... If the unconjugated bilirubin levels are higher than the conjugated bilirubin, this could be caused by hemolytic or pernicious anemia, transfusion reactions, and cirrhosis. If the conjugated bilirubin levels are higher than the unconjugated bilirubin, this is typically due to a malfunction of the liver cells in conjugating the bilirubin. Laboratory tests are generally necessary to determine whether a patient has high levels of unconjugated bilirubin. Urinalyses alone usually aren't sufficient tests for this purpose because urine normally contains a small amount of conjugated bilirubin. As a result, bilirubin tests are conducted by taking and testing a sample of blood. Doctors sometimes use a test called the "van den Bergh Conjugated bilirubin (direct bilirubin) is not reabsorbed from the proximal intestine as mentioned above; in comparison, unconjugated bilirubin is partially reabsorbed across the lipid membrane of the small intestinal epithelium and undergoes enterohepatic circulation. Within the proximal small intestine, there is no additional metabolism of bilirubin, and very little deconjugation takes place. In stark contrast, when the conjugated bilirubin reaches the distal ileum and colon, it is rapidly The normal value for direct bilirubin or conjugated bilirubin is 0.1 - 0.3 mg/dL or 1.7-5.1 mmol/L. For indirect or unconjugated bilirubin, the normal values are 0.2-0.8 mg/dL or 3.4-12.0 mmol/L. Consult your medical practitioner to help understand your bilirubin tests. If your bilirubin levels are high, then this may be indicative of a number of disorders. Certain kinds of infections like cholecystitis or an infected bladder, hereditary diseases like Gilbert's syndrome which
