Stool tests are medical examinations of a person's feces to help diagnose various health conditions. They can detect infections, digestive disorders, and the presence of blood or abnormal substances. These tests are often used to assess gut health and screen for diseases like colorectal cancer. To perform a stool test, a sample of stool is collected and sent to a laboratory for analysis. The results can provide valuable information about a person's digestive system and overall health, guiding doctors in making informed treatment decisions. Regular stool tests can be an important part of preventive health care.
