Fæcesanalyse

Fæcesanalyse, also known as stool analysis or fecal examination, is a laboratory test performed on a stool sample. This analysis is crucial for diagnosing various gastrointestinal diseases, infections, and other health conditions. The examination can include a variety of tests, both macroscopic and microscopic, as well as chemical and microbiological analyses.

Macroscopic examination assesses the appearance of the stool, including its color, consistency, and odor. For instance, black, tarry stools can indicate bleeding in the upper digestive tract, while pale or clay-colored stools might suggest a problem with bile production or flow. The presence of undigested food particles can also provide clues about digestive issues.

Microscopic examination involves looking at a small portion of the stool under a microscope. This can reveal the presence of parasites, their eggs, or specific types of bacteria. White blood cells in the stool can indicate inflammation within the intestines, often associated with bacterial infections or inflammatory bowel diseases like ulcerative colitis or Crohn's disease.

Chemical tests can detect the presence of blood (occult blood test), which may not be visible to the naked eye, and can be an early indicator of gastrointestinal bleeding or colorectal cancer. Other chemical tests might assess fat content, helping to diagnose malabsorption syndromes.

Microbiological analysis involves culturing the stool sample to identify specific bacteria, viruses, or fungi that may be causing an infection. This is particularly important for diagnosing food poisoning or other gastrointestinal infections. Fæcesanalyse is a fundamental tool in gastroenterology and is used to guide treatment decisions for a wide range of digestive disorders.
