Occult Blood in Stool: Exam Helps Detect Changes in the Gastrointestinal Tract
The occult blood in stool test is a simple and important method for identifying small amounts of blood that are not visible to the naked eye.
What is the occult blood in stool test?
This is a laboratory test aimed at checking for microscopic blood in the stool. This finding may be associated with diseases affecting the gastrointestinal tract, especially the stomach, small intestine, or colon. Often, the patient does not exhibit obvious symptoms, which is why the test is recommended as a screening tool, especially for those over 50 years old.
How is the occult blood in stool test performed?
The procedure involves collecting stool samples in appropriate containers provided by the laboratory. The material is then analyzed to identify signs of hemoglobin. Generally, no complex preparation is required, although some laboratories may advise dietary adjustments before the test. The procedure is simple, painless, and provides information that may indicate the need for further investigation, such as colonoscopy or other imaging tests.
How to prepare for the test?
Preparation may vary depending on the laboratory, but in some cases, it is recommended to restrict foods that might interfere with the results, such as red meats, certain vegetables, or specific medications. Following these instructions ensures greater accuracy in the analysis of the collected material.
Positive occult blood in stool: What can it indicate?
A positive result in the test suggests the presence of bleeding at some point in the gastrointestinal tract. This can be associated with conditions such as ulcers, polyps, inflammatory bowel disease, or colorectal cancer. The finding does not immediately define a diagnosis but points to the need for further tests, such as colonoscopy, to clarify the cause.
Which doctor to consult?
The right professional to evaluate the occult blood in stool result is a gastroenterologist. This specialist has the knowledge to investigate the digestive tract, interpret tests, recommend appropriate procedures, and guide treatment based on each case, always considering the patient’s clinical history.
Conclusion
The occult blood in stool test is a tool to identify gastrointestinal changes early.
