Väljaheiteuuringute

Väljaheiteuuringud, known in English as fecal examinations or stool tests, are diagnostic procedures that analyze a sample of a person's feces. These tests are crucial for detecting a wide range of gastrointestinal and systemic health issues. They can identify the presence of bacteria, viruses, parasites, and other microorganisms that may be causing infections or imbalances within the digestive tract.

One common use of fecal examinations is to diagnose infections like Salmonella, Shigella, E. coli, or Clostridium difficile. For parasitic infections, stool tests can reveal the presence of ova (eggs) or the parasites themselves, aiding in the identification of conditions such as giardiasis or amebiasis. Beyond infectious agents, fecal occult blood tests (FOBT) are vital for screening for gastrointestinal bleeding, which can be an early indicator of conditions like ulcers, polyps, or colorectal cancer.

Other types of stool analyses can assess digestive function, such as measuring levels of pancreatic enzymes to diagnose pancreatic insufficiency. Fecal fat analysis can help evaluate the body's ability to absorb fats, pointing towards conditions like celiac disease or Crohn's disease. The appearance, consistency, and color of stool can also provide preliminary clues to a healthcare provider, though laboratory analysis offers definitive diagnostic information. These studies are generally non-invasive and are performed as part of routine check-ups, when gastrointestinal symptoms are present, or as follow-up after treatment.
