The stool guaiac test (or guaiac fecal occult blood test) is conducted to detect the presence of blood in stool that is not apparent to the unaided eye.

[33] The term bowel movement(s) (with each movement a defecation event) is also common in health care.
P. vulgatus does not form spores and is able to grow in mesophilic conditions (37 °C), it is an anaerobe with a DNA GC content of around 41–42%. [7] P. vulgatus is one of the more predominant species in the Bacteroidaceae family, which are one of the five main genera in the human gut microbiome, Bacteroidaceae make up around 30% of fecal isolates.

The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .
