Gmelin's test is a chemical test used for detecting the presence of bile pigments in urine. It is named after Leopold Gmelin, who introduced the test. [1] [2] [3] Five millilitres of urine is slowly added to five millilitres of concentrated nitric acid in a test-tube. Different coloured rings between the two layers are visible if bile pigments ...
Rosenbach's test is a qualitative medical test to detect the presence of bile in urine. To carry out the test, the urine is passed through the same filter paper several times. The filter paper is then dried, and a drop of nitric acid is added. In the presence of bile, the characteristic bile pigment colours appear (a yellow spot with rings of ...
Hay's test, also known as Hay's sulphur powder test, is a chemical test used for detecting the presence of bile salts in urine. [1] Procedure
In the human liver, bile is composed of 97–98% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids, and lecithin), and 200 meq/L inorganic salts. [2] [3] The two main pigments of bile are bilirubin, which is orange-yellow, and its oxidised form biliverdin, which is green.
The bile components that form gallstones include cholesterol, bile salts, and bilirubin. [2] Gallstones formed mainly from cholesterol are termed cholesterol stones, and those formed mainly from bilirubin are termed pigment stones. [2] [3] Gallstones may be suspected based on symptoms. [4] Diagnosis is then typically confirmed by ultrasound. [2]
In parenchymal liver disease and incomplete extrahepatic obstruction, the rise in conjugated bilirubin is less than the complete common bile duct obstruction due to malignant causes. In Dubin–Johnson syndrome , a mutation in multiple drug-resistance protein 2 (MRP2) causes a rise in conjugated bilirubin.
Bilirubin (BR) (from the Latin for "red bile") is a red-orange compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells. [3]
Biliverdin (from the Latin for green bile) is a green tetrapyrrolic bile pigment, and is a product of heme catabolism. [ 1 ] [ 2 ] It is the pigment responsible for a greenish color sometimes seen in bruises .
