Determination of total bilirubin and for the measurement of direct bilirubin the indirect fraction is obtained by subtracting the direct value from the total value. Bilirubin is an endogenous compound that can be toxic under certain conditions but, on the other hand, mild unconjugated hyperbilirubinaemia might protect against cardiovascular diseases and tumour development.

Bilirubin is one of the most commonly used tests to assess liver function approximately 85% of the total bilirubin produced is derived from the heme moiety of hemoglobin, while the remaining 15% is produced from the red blood cell precursors destroyed in the bone marrow and from the catabolism of. What is a high total bilirubin count normal results for a bilirubin test are 01 to 1 milligram per deciliter of total bilirubin and 0 to 03 milligrams per deciliter of direct bilirubin, according to mayo clinic doctors consider anything higher to be elevated levels of bilirubin bilirubin is a. For these reasons determination of total bilirubin was thought preferable in order to select an adequate reaction time, colour development was followed at 530 nm in the recording spectrophotometer coupling of bilirubin in the absence of urine is complete in less than 25 sec.

Highly selective and accuracy in the determination of the bilirubin concentration but interferes with other heme containing proteins (eg haemoglobin) and pigments. Bilirubin is a breakdown end product of heme containing proteins about 80% of bilirubin is formed from the degradation of erythrocyte hemoglobin after 120 days of erythrocyte life in the blood.
Bilirubin, a degradation product of heme catabolism, is a non-polar molecule there are two forms of bilirubin: water-soluble (conjugated or direct) and water-insoluble (unconjugated or indirect) bilirubin. The large number of modern methods which have been published for the determination of total bile pigments in the blood plasma indicates the difficulties of the estimation and suggests the need for a reliable standard method in view of the present importance of plasma bilirubin levels in the. 484 determination of bilirubin after addition of the serum, tube 1 being used for the initial adjustment of the galvanometer.
