  2. Neonatal jaundice - Wikipedia

    en.wikipedia.org/wiki/Neonatal_jaundice

    In the newborn liver, activity of glucuronyl transferase is only at 0.1-1% of adult levels, so conjugation of bilirubin is already reduced. Further inhibition of bilirubin conjugation leads to increased levels of bilirubin in the blood. [ 18 ]

  3. Jaundice - Wikipedia

    en.wikipedia.org/wiki/Jaundice

    Jaundice in infants, as in adults, is characterized by increased bilirubin levels (infants: total serum bilirubin greater than 5 mg/dL). Normal physiological neonatal jaundice is due to immaturity of liver enzymes involved in bilirubin metabolism, immature gut microbiota, and increased breakdown of fetal hemoglobin (HbF). [ 54 ]

  4. Hyperbilirubinemia in adults - Wikipedia

    en.wikipedia.org/wiki/Hyperbilirubinemia_in_adults

    Serum tests evaluate plasma bilirubin, haemolysis and liver function and are essential for definitive diagnosis. When total serum bilirubin exceeds 2.5 mg/dL and unconjugated bilirubin occupies >85% of total amount, it is classified as unconjugated hyperbilirubinemia. [6]

  5. Gilbert's syndrome - Wikipedia

    en.wikipedia.org/wiki/Gilbert's_syndrome

    People with GS predominantly have elevated unconjugated bilirubin, while conjugated bilirubin is usually within the normal range or is less than 20% of the total. Levels of bilirubin in GS patients are reported to be from 20 μM to 90 μM (1.2 to 5.3 mg/dl) [38] compared to the normal amount of < 20 μM. GS patients have a ratio of unconjugated ...

  6. Hemolytic jaundice - Wikipedia

    en.wikipedia.org/wiki/Hemolytic_jaundice

    Normal colour of the patient's urine indicates the absence of unconjugated bilirubin. [27] Results from the urine test should be confirmed by a complete blood count (CBC) and serum testing for total serum bilirubin and fractionated bilirubin. [32]

  7. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

  8. Van den Bergh reaction - Wikipedia

    en.wikipedia.org/wiki/Van_den_Bergh_reaction

    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]

    Reference ranges for urine tests are described below: Measurement Lower limit Upper limit Unit ... Bilirubin: n/a: 0 / negative [2] Blood: n/a: 0 / negative [2 ...
