Protein Denaturation Quiz

Summary of AUBF LAB Tests for Protein and Glucose

• AUBF LAB offers tests for protein and glucose in urine samples.
• The protein test is based on the denaturation of protein or albumin, which causes precipitation when boiled in an acidic medium.
• Reagents used for the protein test include heat to denature the proteins and acetic acid to enhance precipitation and sensitivity.
• A positive result for the protein test is indicated by precipitation or cloudiness in the urine sample.
• The glucose test uses Benedict's reagent, a chemical solution that detects reducing sugars in a sample.
• The principle behind the glucose test is the reaction between reducing sugars and Benedict's reagent.
• For the glucose test, a positive result is indicated by a color change in the presence of reducing sugars.
• The Heller's test is another protein test that relies on the precipitation of proteins in the presence of mineral acids like nitric acid.
• The precipitation of proteins by acids is dependent on changes in the pH of the solution.
• In the Heller's test, nitric acid is used to acidify the urine sample.
• A positive result for the Heller's test is indicated by the formation of a white ring at the point of contact.
• The AUBF LAB tests for protein and glucose are used to assess the levels of these substances in urine samples.
