Stool examination from patients infected with rotavirus reveals watery or soft stools, which rarely have gross blood and usually are guaiac-test .
To prepare a wet mount, obtain a microscope slide and the stool specimen. Take a small amount of the specimen and place it on a microscope slide. If the stool specimen is still somewhat solid, add a drop or two of saline to the specimen and mix. Ideally, two smears can be prepared on one slide, of which one can be stained with iodine. Microbiological Stool Exam: Overview Stool (feces) is an important body substance to check for the presence of disease-causing microorganisms, particularly parasites and bacteria. For the most part, laboratories use microbiology tests – similar to microbiological blood tests – to determine if disease-causing microorganisms are present.

A stool analysis is a series of tests done on a stool (feces) sample to help diagnose certain conditions affecting the digestive conditions can include infection (such as from parasites, viruses, or bacteria), poor nutrient absorption, or cancer.
For a stool analysis, a stool sample is collected in a clean container and then sent to the laboratory. Stool test is usually performed to detect the presence of any type of bacteria or parasites that are present in the intestine and infecting the gut.
Gastroenterologists can diagnose any variety of diseases by analyzing the changes in the stools color, consistency, pH balance and the presence of fats. Microscopic examinations done on fecal sample are shown in Figure Collection of Specimen for Parasites.
A random specimen of stool (at least 4 ml or 4 cm³) is collected in a clean, dry, container with a tightly fitting lid (a tin box, plastic box, glass jar, or waxed cardboard box) and transported immediately to the laboratory (this is because trophozoites of Entameba histolytica.
A History of Fecal Occult Blood Test Fecal Immunochemical Test (FIT) Ismar Boas, MD, German gastroenterologist established the guaiac test method George Barrows, MD, and colleagues developed the fecal immunochemical tests. What is being tested. The stool culture is a test that detects and identifies bacteria that cause infections of the lower digestive tract.
The test distinguishes between the types of bacteria that cause disease and the types that are normally found in the digestive tract (normal flora).The test helps to determine if pathogenic bacteria are the cause of gastrointestinal symptoms (gastroenteritis). Food handlers do not require periodic stool examinations.
However, periodic examination of stool for presence of parasites can be a useful in high risk environments as a mechanism to highlight the importance of hand washing at all times.
But the results from one week do not predict the results for the following week. Several indirect methods for assessing lactose digestion are available, including blood, urine, stool, and breath tests. Blood tests involve feeding a standard g lactose dose and measurement of plasma glucose every 15–30 minutes over a period of 30 minutes to 2 hours.
The most common test done on a stool is called fecal occult blood test (FOBT) wherein it can detect traces of blood in the feces. Feces is a solid body waste discharged from the large intestine through the anus by the process of defecation.
