Fecal leakage, fecal soiling and fecal seepage are minor degrees of FI, and describe incontinence of liquid stool, mucus, or very small amounts of solid stool. They cover a spectrum of increasing symptom severity (staining, soiling, seepage, and accidents). [1] Rarely, minor FI in adults may be described as encopresis.
Cultures of stool samples are examined to identify the organism causing dysentery. Usually, several samples must be obtained due to the number of amoebae, which changes daily. [17] Blood tests can be used to measure abnormalities in the levels of essential minerals and salts. [17]
Rectal discharge is intermittent or continuous expression of liquid from the anus ().Normal rectal mucus is needed for proper excretion of waste. Otherwise, this is closely related to types of fecal incontinence (e.g., fecal leakage) but the term rectal discharge does not necessarily imply degrees of incontinence.
No laboratory standards have been agreed upon, [41] so recommendations vary for size of sample to be prepared, ranging from 30 to 100 grams (1.1 to 3.5 ounces) of fecal material for effective treatment. [13] [37] [39] [42] Fresh stool is used to increase viability of bacteria within the stool [41] [42] and samples are prepared within 6–8 hours.
Feces is the scientific terminology, while the term stool is also commonly used in medical contexts. [30] Outside of scientific contexts, these terms are less common, with the most common layman's term being poop or poo. The term shit is also in common use, although it is widely considered vulgar or offensive. There are many other terms, see below.
A study on parasites in stool samples in the United States during 2000 found blastocystosis to be the most common parasitic infection in the population, occurring in 23% of individuals. [90] [92] A Canadian study of samples received in 2005 identified Blastocystis as the most prevalent protozoal infection identified. [91]
