the normal level will be will be 1 mg/dl. Normal results forconjugated(direct) bilirubin should be less than 0.3 mg/dl. Normal bilirubin levels in newborns can reach as high as 12 mg/dl.
Causes of Abnormally High Levels • Prehepatic (increases in unconjugated bilirubin) from anorexia, intravascular or extravascular hemolytic anemia or severe rhabdomyolysis. Certain drugs can also increase the unconjugated bilirubin fraction (especially heparin, steroids). There is one report of persistent...
high, factitious elevation of the direct fraction has been reported. Experimental evidence indicates that the minute fraction of bilirubin that is not bound to albumin, referred to as the unbound or “free” bilirubin concentration, correlates more strongly with bilirubin toxicity than does total ...
Bilirubin is a yellow-orange pigment produced from the breakdown of red blood cells. Conjugated vs. Unconjugated Bilirubin There are two types of bilirubin: Conjugated bilirubin, also known as direct bilirubin Unconjugated bilirubin, also known as indirect bilirubinView...

Direct bilirubin is one of the two types of bilirubin, a brownish pigment found in bile. This type of bilirubin is water-soluble...
After the publication of the Bhutani et al1hour-specific bilirubin nomogram, other attempts have been made to stratify infants at high risk for needing treatment for hyperbilirubinemia. Sarici et al14evaluated 136 term newborns with ABO incompatibility, 6 of whom had direct Coombs-positive results...
Serum bilirubin is determined by: (i) diazo transfer reaction, currently, the gold-standard measurement method; (ii) high-performance liquid chromatography (HPLC); (iii) oxidative, enzymatic, and chemical methods; (iv) direct spectrophotometry; and (v) transcutaneous methods [15]. Since it was ...
Septicaemia, parenteral nutrition and androgens are some extrahepatic causes of conjugated hyperbilirubinaemia. About 80% conjugated bilirubin is measured in the direct bilirubin assay, together with small amounts of delta-bilirubin and unconjugated bilirubin. In non-acetaminophen-induced acute liver ...
The available knowledge on reactivity of glial cells to bilirubin and on the impairment to neuronal network dynamics that it causes, here summarized, suggests that a better comprehension of the interplay between neurons and glia is essential to understand bilirubin neurotoxicity and highlight potential ...
