Fecal calprotectin. Qualitative determination.

Recommendations:

• The stool is delivered to the laboratory for examination within 2 hours of collection. If the delivery time exceeds 2 hours, it is necessary to use containers with a preservative for transporting the material.
• The container with feces is tightly closed with a lid, packed in a clean disposable bag and delivered to the laboratory.
• Stools should not be submitted for testing after an enema, suppository insertion, or castor oil administration. Stools for testing should not contain foreign substances, such as urine.
• In newborn babies, feces are collected from the diaper or nappy immediately after defecation.

Gastrointestinal diseases are a serious problem for many people around the world. They can occur for various reasons and have a different clinical picture, which makes their diagnosis and treatment a difficult task for doctors. One method of diagnosing such diseases, which is gaining popularity, is the determination of the level of fecal calprotectin in the stool samples of patients. In this article, we will look at what fecal calprotectin is, how it helps in the diagnosis and monitoring of gastrointestinal diseases and why this method is becoming increasingly popular among doctors and patients.

Fecal calprotectin is a protein produced by neutrophil granulocytes, one of the main cells of the immune system involved in the body's inflammatory reactions. Calprotectin has high levels in the blood and feces during inflammatory processes that occur in the gastrointestinal tract. Therefore, determining the level of calprotectin in feces can serve as an indicator of inflammation in the intestine.

Why is it important to measure calprotectin levels in stool? First, this test helps in the diagnosis of inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis. These diseases are characterized by chronic inflammation of the intestines, and their diagnosis can be important for timely and effective treatment. Determining the level of calprotectin can help doctors establish a diagnosis and determine the extent of inflammation.

Second, fecal calprotectin testing can be used to monitor the effectiveness of treatment. After treatment is started, doctors can regularly measure fecal calprotectin levels to see if the inflammation in the intestines is decreasing as a result of the treatment. This helps doctors make informed decisions about further treatment and adjust treatment tactics according to the patient's current condition.

It is important to note that the determination of calprotectin in feces is a non-invasive and painless diagnostic method. Patients do not need to undergo complex procedures or preparation for the analysis, as in the case of colonoscopy or other invasive methods. Simply collect a stool sample and submit it for analysis.

However, it is important to note that elevated levels of calprotectin in stool are not specific indicators of a particular disease. They can also be elevated in cases of other inflammatory processes in the body. Therefore, the results of the analysis should be interpreted in conjunction with clinical symptoms and other diagnostic methods.

In conclusion, fecal calprotectin is an important tool for the diagnosis and monitoring of gastrointestinal diseases. It helps doctors to make a timely diagnosis, assess the degree of inflammation and monitor the effectiveness of treatment. This method allows patients to get a quick and non-invasive assessment of their condition and improve their quality of life through rational treatment.
