A stool test is a medical diagnostic technique that involves the collection and analysis of fecal matter. Microbial analysis (culturing), microscopy and chemical ...
For best isolation results, it is imperative that fecal samples be collected, refrigerated and sent to the diagnostic laboratory as soon as possible to maintain sample integrity. [4] For rectal swabs, Amies or Cary–Blair transport mediums are recommended in order to protect the sample from toxic effects of oxygen on Campylobacter species. [4]
After the sample is inoculated into or onto the choice media, they are incubated under the appropriate atmospheric settings, such as aerobic, anaerobic or microaerophilic conditions or with added carbon dioxide (5%), at different temperature settings, for example 37 °C in an incubator or in a refrigerator for cold enrichment, under appropriate ...

The stool guaiac test involves fasting from iron supplements, red meat (the blood it contains can turn the test positive), certain vegetables (which contain a chemical with peroxidase properties that can turn the test positive), and vitamin C and citrus fruits (which can turn the test falsely negative) for a period of time before the test.
Consequently, the National Technical Advisory Committee in the US recommended the following standard for recreational waters in 1968: 10 percent of total samples during any 30-day period should not exceed 400 fecal coliforms/100 mL or a log mean of 200/100 mL (based on a minimum of 5 samples taken over not more than a 30-day period). [7]
By growing and counting colonies of fecal coliform bacteria from a sample of water, the amount of bacteria originally present can be determined. Membrane filtration is the method of choice for the analysis of fecal coliforms in water. Samples to be tested are passed through a filter of a particular pore size (generally 0.45 micrometre). The ...
