Photometric determination of bilirubin, the content of the latter was analysed in a group of 23 gallstone specimens consisting of various amounts of bilirubin and cholesterol. Bilirubin determination methods as regards miscellaneous mcqs and notes from the gastroenterology handbook.
Bilirubin determination methods are also needed in the preparation of this commercial product bilirubin reacts with diazobenzene-p-sulfonic acid to form two isomeric azopigments of identical light absorption properties commonly, these two isomeric azopigments are collectively referred to as azobilirubin. Determination of total bilirubin in neonatal and adult serum, adapted to the technicon ra-1000 analyzer clin chem 198935:1980–6 8 rolinski b, kuster h, ugele b, horn k total bilirubin measurement by photometry on a blood gas analyzer: potential for use in neonatal testing at the point of care clin chem 200147:1845–7 9. A method for the determination of both direct and indirect serum bilirubin on the autoanalyzer is described which has a number of advantages over the automated method that is currently recommended.
Mlab 2401 - clinical chemistry lab manual c f 113 unit: total and direct bilirubin 13biliwpd task inst - info 69, sb-0260-200 for stanbio kit determination of total and direct bilirubin. 2 perform a total bilirubin determination 3 perform a direct bilirubin determination introduction like so many other substances measured in clinical chemistry laboratories, bilirubin is a waste product bilirubin, the principle pigment in bile, is derived from the breakdown of hemoglobin.
Unconjugated bilirubin (indirect bilirubin) concentration is calculated by subtracting the direct-reacting fraction from total bilirubin direct reacting bilirubin slightly overestimates the conjugated bilirubin concentration because a fraction of unconjugated bilirubin (about 10 to 15 %) also gives a direct van den bergh reaction.

Conversion of the bilirubin concentration in terms of mg per cc of colored solution to mg per 100 cc of serum is made by means of the formula x= 2 - log g kl x x 100 where x is mg of bilirubin per 100 cc of serum, v is the volume of colored solution, and a is the amount of serum used.
