In acute appendicitis, total bilirubin can rise from 20.52 μmol/L to 143 μmol/L. In pregnant women, the total bilirubin level is low in all three trimesters. The measurement of bilirubin levels in the newborns is done through the use of bilimeter or transcutanoeus bilirubinometer instead of performing LFTs.
Blood test results are advised to always be interpreted using the reference range provided by the laboratory that performed the test. The SI units are μmol/L. Typical ranges for adults are: 0–0.3 mg/dl – Direct (conjugated) bilirubin level; 0.1–1.2 mg/dl – Total serum bilirubin level
The level of total bilirubin is often further increased if the blood sample is taken after fasting for two days, and a fast can, therefore, be useful diagnostically. A further conceptual step that is rarely necessary or appropriate is to give a low dose of phenobarbital : [41] the bilirubin will decrease substantially.
Jaundice, also known as ICTERUS, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. [3] [6] Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. [7]
Hyperbilirubinemia is a clinical condition describing an elevation of blood bilirubin level due to the inability to properly metabolise or excrete bilirubin, a product of erythrocytes breakdown. In severe cases, it is manifested as jaundice, the yellowing of tissues like skin and the sclera when excess bilirubin deposits in them. [1]
Hemolytic jaundice. Hemolytic jaundice, also known as prehepatic jaundice, is a type of jaundice arising from hemolysis or excessive destruction of red blood cells, when the byproduct bilirubin is not excreted by the hepatic cells quickly enough. [1] Unless the patient is concurrently affected by hepatic dysfunctions or is experiencing ...
Van den Bergh reaction is a chemical reaction used to measure bilirubin levels in blood. [1] [2] More specifically, it determines the amount of conjugated bilirubin in the blood. The reaction produces azobilirubin . Principle: bilirubin reacts with diazotised sulphanilic acid to produce purple coloured azobilirubin. [3]
Hemolytic anemia or haemolytic anaemia is a form of anemia due to hemolysis, the abnormal breakdown of red blood cells (RBCs), either in the blood vessels (intravascular hemolysis) or elsewhere in the human body (extravascular). [2] This most commonly occurs within the spleen, but also can occur in the reticuloendothelial system or mechanically ...
