Suspected hepatitis - the total bilirubin level is divided between conjugated (direct) and unconjugated (indirect) studies. A marked increase in the bilirubin level ranging from 5 to 20 mg/dL may occur 3.5 to 5.5 months after exposure; an elevation of greater than 20 mg/dL suggests severe disease. 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. Conjugated and direct bilirubin were measured in 288 samples from 107 neonates less than 15 days old. Retrospective analysis of the medical records showed that 53 neonates were hepatobiliary-normal, 42 patients had no obvious evidence of hepatobiliary disease but had received total parenteral nutrition, and 12 were clearly hepatobiliary-abnormal. Key Difference – Direct vs Indirect Bilirubin Bilirubin is the catabolic product of haemoglobin.Bilirubin exists in two main forms; conjugated and unconjugated bilirubin.The metabolism of bilirubin takes place predominantly in the liver.Bilirubin enters the liver in the unconjugated form and thereby converted to the conjugated form after some metabolic conversions. Conjugated (“direct”) bilirubin. This is the bilirubin once it reaches the liver and undergoes a chemical change. It moves to the intestines before being removed through your stool. This conjugated bilirubin is direct and water-soluble. It goes into the duodenum. In the guts, there are processes of deconjugation оf the bilirubin and reduction from the intestinal bacterial flora to the formation of urobilinogen. Approximately 20% of it is reabsorbed and enters the hepatocyte again via the enterohepatic pathway Difference between indirect and direct bilirubin: Indirect bilirubin also known as uncojugated bilirubin is produced from the breakdown of red blood cells in the circulatory system in spleen, liver and slightly in bone marrow. 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. Therefore, the amount of conjugated bilirubin present in serum in healthy subjects is trivial (<10% of measured total bilirubin). An elevated level of conjugated serum bilirubin implies liver disease. Also, it is important to note that only conjugated bilirubin appears in urine (unconjugated bilirubin is albumin bound and water insoluble). Bilirubin in this second phase is called “direct” or “conjugated” bilirubin. Total bilirubin is the sum of your direct and indirect bilirubin levels. Benefits of Bilirubin. Bilirubin is not just a waste product. In recent decades, science has been uncovering the beneficial roles bilirubin plays in our bodies.
