Anwendung
Gum guaiac is a tree resin and crude source of 2,5-di-(4-hydroxy-3-methoxyphenyl)-3,4-dimethylfuran (α-guaiaconic acid).[1] The phenolic α-guaiaconic acid acts as a colorimetric peroxidase substrate.[2][3][4] When reacted with an organic or inorganic oxidizing agent, the α-guaiaconic acid is oxidized to a blue-colored quinone. The guaiac reaction has been used to detect trace amounts of heme from hemoglobin in the presence of peroxide.
The Nobles test can be performed using 67% (w/v) gum guaiac diluted in 96% ethanol to analyze the level of extracellular oxidase production [5]

There is increasing evidence that faecal immunochemical tests (FITs) for haemoglobin offer a number of advantages over traditional guaiac based faecal occult blood tests (gFOBTs). However, evidence on diagnostic performance from direct comparisons with colonoscopy findings in all participants in

Guaiac-based fecal occult blood tests (gFOBTs) are the most commonly applied tests for colorectal cancer screening globally but have relatively poor sensitivity to detect colorectal neoplasms. Men have higher prevalences of colorectal neoplasms than women. In case of a positive
