When the hydrogen peroxide is dripped on to the guaiac paper, it oxidizes the alpha-guaiaconic acid to a blue colored quinone.

Proposed oxidations of compounds in guaiac oil as explanation for the formation of the blue bis-methylenequinone as part of the guaiac test.

Increased powers are attributed to sculptures which are crafted from materials of significant origin, such as the last guaiac tree and cedar wood.

The two inventors created a compound of two acids _ guaiac acid and ABTS acid _ together with a dye that is added to the silicon gel.

The stool guaiac test was originally the principal colon cancer screening technology available, but modern tests which look for globin or DNA are now also available.
17.
The stool guaiac test method may be preferable to fecal immunochemical testing ( FIT ) if there is a clinical concern about possible gastric or proximal upper intestinal bleeding.
18.
Even when using anticoagulants a high proportion of positive guaiac tests were found to be due to diagnosable lesions, suggesting anticoagulants may not cause bleeding unless there is an abnormality.
19.
Though the FIT test is preferred, even the guaiac FOB testing of average risk populations may have been sufficient to reduce the mortality associated with colon cancer by about 25 %.
20.
Oil of guaiac is primarily composed of 42-72 % guaiol, bulnesol, ?-bulnesene, ?-bulnesene, ?-guaiene, guaioxide and ?-patchoulene.
