BILIRUBIN TOTAL & DIRECT
In vitro diagnostic test kit, for professional use only
Concentration in Sample (mg/dl) = (Abs. of Sample – Abs. of Sample Blank) X 14 (mg/dl)
Concentration in Sample (µmol/L)= (Abs. of Sample – Abs. of Sample Blank) X 239 (µmol/L)
INTENDED USE : Quantitative in vitro determination of concentration of Bilirubin in
CONVERSION FACTOR : mg/dl X 17.1 = µmol/L
serum on photometric systems.
For the calibration of automated photometric systems use of the commercially available calibrator is recommended. QUALITY CONTROL :
CLINICAL SIGNIFICANCE : Red blood cells at the end of their circulating life are broken
To ensure adequate quality, use of the commercially available control sera is down in the reticulo-endothelial systems, mainly the spleen. The resulting haem, once the iron is removed, is then converted to bilirubin (yellow orange bile pigment). Water insoluble bilirubin is called indirect or un-conjugated bilirubin is then released into the MEASURING RANGE:
blood stream where it binds tightly to albumin and is transported to the liver. In the liver The test has been developed to determine Bilirubin concentrations within a measuring un-conjugated bilirubin binds with glucoronic acid (mono and di glucoronides) to form range from 0.05 to 25 mg/dl (0.85 to 427.5 µmol/L). When values exceed higher limit of conjugated bilirubin (direct bilirubin) by the enzyme glucoronyl transferase. Conjugated the range, such samples should be diluted 1 + 1 with NaCl solution (9 g/I) and the result bilirubin or direct bilirubin is excreted via the biliary system into the intestine. multiplied by 2.
Total bilirubin is the sum of un-conjugated bilirubin and conjugated fractions. Bilirubin is SPECIFICITY / INTERFERENCE :
