Reverse Camp Test: A Sensitive Screening Tool For Bilirubin Detection In Liver Disorders

The Reverse Camp Test utilizes the Gmelin test (oxidation of bilirubin to biliverdin by nitric acid) and the Fouchet test (condensation of biliverdin with trichloroacetic acid to form a green compound). The reagent contains nitric acid, trichloroacetic acid, and ferric chloride. When bilirubin in urine interacts with the reagent, it is oxidized to biliverdin, which then condenses to form a green compound. The presence of a green ring at the urine-reagent junction indicates the presence of bilirubin, with the intensity of the color correlating to the bilirubin concentration. The test is primarily used as a screening test to detect bilirubin in urine, aiding in the diagnosis of liver and biliary tract disorders.

The Reverse Camp Test, a vital tool in diagnosing liver and biliary tract ailments, relies on a meticulously crafted reagent to detect bilirubin in urine. This reagent is not just a simple concoction but a symphony of chemicals, each playing a specific role in the test’s success.

Ferric Chloride (FeCl3)

The backbone of the reagent, ferric chloride is an inorganic compound that eagerly donates an iron ion to the reaction. This iron ion serves as a catalyst, facilitating the conversion of bilirubin into biliverdin.

Nitric Acid (HNO3)

Nitric acid might sound daunting, but in this reagent, it acts as a dehydrating agent. It effectively removes water molecules from the reaction site, creating the optimal conditions for the iron-catalyzed oxidation of bilirubin.

Sodium Nitrite (NaNO2)

Sodium nitrite, often overlooked, plays a clever role in this chemical dance. It’s an acidifying agent, lowering the pH of the solution and ensuring that the reaction proceeds smoothly.

Potassium Iodide (KI)

Potassium iodide, a humble yet essential reagent, aids in the conversion of bilirubin into biliverdin. It helps generate iodine, which serves as an electron donor in the reaction, enabling the transfer of electrons from bilirubin to iron.

Acetic Acid (CH3COOH)

Acetic acid, the mildest of the ingredients, performs a vital dual role. It acidifies the solution, aiding in the removal of water molecules, and also stabilizes the biliverdin product, preventing it from further oxidation.

Together, these components orchestrate a chemical transformation, transforming bilirubin into biliverdin. This color change is the telltale sign that bilirubin is present in the urine, providing valuable insight into the health of the liver and biliary tract.
