 (bĭl′ĭ-ro͞o′bĭn, bĭl′ĭ-ro͞o′-)
n.
A reddish-yellow bile pigment, C33H36N4O6, derived from the degradation of heme.

bilirubin

(ˌbɪlɪˈruːbɪn; ˌbaɪ-)
n
(Physiology) an orange-yellow pigment in the bile formed as a breakdown product of haemoglobin. Excess amounts in the blood produce the yellow appearance associated with jaundice. Formula: C32H36O6N4
[C19: from bile1 + Latin ruber red + -in]

(ˈbɪl əˌru bɪn, ˌbɪl əˈru bɪn)

Serum direct bilirubin concentration increases, as does the amount of conjugated bilirubin in the urine, leading to very dark urine.
Because DTB is almost invariably present in commercial controls and calibrators (total bilirubin and direct bilirubin assays are calibrated with a single solution), manufacturers of bilirubin assays based on direct spectrophotometry need to be aware of the dependence of the DTB spectrum on the protein matrix and pH.
Lin-Trol[R] total and direct bilirubin linearity calibrators were purchased from Sigma Chemical Company.
Alanine aminotransferase (ALT), albumin, alkaline phosphatase (ALK), aspartate aminotransferase (AST), direct bilirubin, total bilirubin, calcium, total carbon dioxide (tC[O.

Additionally, direct bilirubin was determined by the method of Jendrassik and Grof (7) in 56 samples, and hemolysis, lipemia, and icterus were determined by multiple-wavelength photometry in 63 samples.
Albumin, pseudocholinesterase (PCHE), alkaline phosphatase, [gamma]-glutamyltransferase, cholesterol, LDL- and HDL-cholesterol, triglycerides, total and direct bilirubin, and aspartate and alanine aminotransferase (AST and ALT) were measured using standard methodologies (Boehringer).
The following serum tests should be used to evaluate patients with known or suspected liver disease: AST, ALT, ALP, total bilirubin, direct bilirubin, total protein, and albumin (IIIB, E).
In each subject, after an overnight fast, plasma concentrations of total and direct-reacting bilirubin were determined by a diazo method at least three times within 6 months before the study; indirect bilirubin was calculated as total minus direct bilirubin.

The lower limit of the fetal reference interval for calcium was below that of adults, but the upper limits of the fetal reference interval for chloride, inorganic phosphorus, and direct bilirubin were higher.
