Abstract This study compares total and direct-reacting bilirubin values in 40 serum samples from patients with various diagnoses, as measured by automated methods (Beckman Synchron CX-5, Beckman Astra 8, Kodak Ektachem 700) and HPLC and by a manual method for delta bilirubin. For total bilirubin, within-run CVs were less than 6%. The Ektachem 700 method underestimated bilirubin with serum samples from patients with Crigler-Najjar syndrome and from newborns in whom unconjugated bilirubin concentrations were increased but conjugated bilirubins were not present or were present only in small amoun

SUMMARY We investigated the occurrence of covalently protein-bound bilirubins in the plasma of dogs with hyperbilirubinemia attributable to hepatobiliary diseases or Coombs test-positive hemolysis. The bilirubins in plasma were measured with the conventional Van den Bergh reaction, by treatment with diazotized p-iodoaniline, and by high-performance liquid chromatography of bilirubin and its methylesters after alkaline methanolysis. All but one dog had covalently protein-bound bilirubin conjugates. The concentration and the fraction of total bilirubins varied in all diseases investigated, but t

Abstract Guidelines for managing hyperbilirubinemia in newborns were developed by using diazo methods that measure total and direct-reacting bilirubins and calculate an indirect fraction.

<strong>Background:</strong>&nbsp;Neonatal Icterus in in newborns is a serious condition. It&rsquo;s one of the most common reasons of infant immaturity. The total investigation of complete serum bilirubin (TSB) is a widely known procedure for identifying hyperbilirubinemia, but it is intrusive for neonates. TCB (TCB) was used to assess bilirubin levels since over 2 decades as just a non-invasive and painless method. Acute bilirubin encephalopathy, commonly referred as kernicterus, is indeed a bilirubin toxicity which is linked to significant morbidity and mortality. The focus of this research

Abstract:
Total bilirubin consists of an unconjugated form, solubilized by its binding to albumin, and a conjugated form representing a minor part of the circulating bilirubin. As total bilirubin in physiological concentrations is a powerful antioxidant, its concentration gradient may reflect the health status of an individual, and serve as a prognostic indicator of outcome in primary and secondary cardiovascular disease prevention. The aim of this study was to assess the association between total bilirubin and incident cardiovascular events following a myocardial infarction. Total bilirubin in serum wa

Background: Jaundice in newborns is a prevalent postnatal complication, typically benign in nature. To assess neonatal jaundice, the development of non-invasive techniques, such as the transcutaneous bilirubinometer, has proven instrumental. This study focuses on evaluating neonatal bilirubin levels using transcutaneous bilirubin (TcB) meters, which employ a non-invasive approach by measuring light transmission through the skin.&#x0D; Objective: The objective of this research is to conduct a comparative analysis between transcutaneous bilirubin levels in neonates and their corresponding total

Increased serum total bilirubin levels have been reported in patients with monoclonal gammopathy. There is also one report of decrease in direct bilirubin due to paraprotein interference.

Abstract:
Hyperbilirubinemia is a common pathological condition in neonates. Free bilirubin can penetrate the blood–brain barrier (BBB), which can lead to bilirubin neurotoxicity. In the context of predicting the risk of bilirubin neurotoxicity, although the specificity and sensitivity of free bilirubin levels are higher than those of total serum bilirubin (TSB), free bilirubin is not widely monitored in clinical practice. The threshold TSB levels at which phototherapy must be administered have been established previously. However, TSB levels are not well correlated with neurodevelopmental outcomes. Cur

Abstract The effects of light on serum bilirubin subfractions in vitro were investigated by HPLC and four routine methods for bilirubin analysis. By HPLC, the rate of photodegradation of unconjugated bilirubin (Bu) was nearly twice that of monoconjugated bilirubin (mBc) and threefold that of diconjugated bilirubin (dBc); delta bilirubin (Bd) was most stable against photoirradiation. In the diazo method, the rate of photodegradation of direct bilirubin was almost the same as that of the sum of mBc, dBc, and Bd determined by the HPLC method. However, the rate of photodegradation of indirect bili
