Introduction
Fecal occult blood test usually yields results within 0.5 to 1 hour. Normally, human stool does not contain blood. Fecal occult blood refers to the presence of small amounts of red blood cells in the stool that cannot be seen with the naked eye and must be confirmed through chemical methods or other testing techniques. Fecal occult blood is primarily diagnosed through fecal occult blood testing.
Fecal occult blood test results are generally available within 0.5 to 1 hour. The detailed explanation is as follows:
Under normal circumstances, human stool does not contain blood. Fecal occult blood refers to the presence of small amounts of red blood cells in the stool that cannot be seen by the naked eye and must be confirmed through chemical methods or other testing techniques. Fecal occult blood is primarily diagnosed using a fecal occult blood test, which usually involves an immunochemical test strip. The special reagent on the test strip reacts with hemoglobin in red blood cells, causing a color change on the strip, thereby indicating the presence of blood in the stool. This testing method is quick and cost-effective, with results typically available within 0.5 to 1 hour. If a patient is diagnosed with fecal occult blood, additional tests should be performed to determine the underlying cause so that appropriate treatment can be provided.
Patients are advised to maintain a light diet before the test and avoid foods containing animal blood. Female patients should schedule the test outside of their menstrual period to avoid interference with the results.
