What is the principle of the guaiac reaction?
The guaiac reaction is based on the principle that the guaiac molecule interacts with certain substances, like blood, causing a color change that indicates the presence of those substances. This reaction is often used to detect the presence of blood in samples, for example in fecal occult blood tests.
Which of the following is the primary purpose of a guaiac test?

What is stool guaiac?
Stool guaiac is a diagnostic test used to detect the presence of hidden (occult) blood in a person's stool, which can indicate gastrointestinal bleeding. The test involves applying a small sample of stool to a guaiac-based reagent, which changes color in the presence of hemoglobin. It is commonly used as a screening tool for conditions such as colorectal cancer or gastrointestinal disorders.

What tests is used to detect occult blood?
Occult blood is typically detected using the fecal occult blood test (FOBT), which analyzes stool samples for hidden blood that may indicate gastrointestinal bleeding. There are two main types of FOBT: guaiac-based tests and immunochemical tests (FIT). Guaiac-based tests use a chemical reaction to detect heme, while FIT specifically identifies human hemoglobin. Both tests are commonly used for colorectal cancer screening and diagnosing gastrointestinal disorders.

What is a Guaiac oil?
Oil of guaiac is a fragrance used in soap. It comes from the palo santo tree (Bulnesia sarmientoi). Oil of guaiac is produced through steam distillation of a mixture of wood and sawdust from palo santo. It is sometimes incorrectly called guaiac wood concrete. It is a yellow to greenish yellow semi-solid mass which melts around 40-50º C. Once melted, it can be cooled back to room temperature yet remain liquid for a long time. Oil of guaiac has a soft roselike odour, similar to the odour of Hybrid tea roses or violets. Because of this similarity, it has sometimes been used as an adulterant for rose oil. Oil of guaiac is primarily composed of 42-72% guaiol, bulnesol, d-bulnesene, b-bulnesene, a-guaiene, guaioxide and b-patchoulene. It is considered non-irritating, non-sensitizing, and non phototoxic to human skin.
