How Does Fecal Occult Blood Testing Work?
Fecal occult blood testing is a stool-based test that detects hidden blood in your digestive tract. The test uses either traditional chemical methods or immunochemical tests to reveal blood that isn't visible. It's widely used for screening, especially in detecting sources of iron deficiency anemia or early signs of colorectal cancer.
Why is This Test Important?
The fecal occult blood test is a non-invasive, simple method for detecting potential health issues. It has a sensitivity of 58% and a specificity of 84% for identifying sources of iron deficiency anemia. This high sensitivity makes it a valuable tool in early detection, potentially uncovering conditions like GI bleeding or colorectal cancer before they become severe.
What Happens After a Positive Test?
If your test results are positive, further evaluation is crucial. The next steps often include colonoscopy and possibly upper endoscopy to find the bleeding source. If both tests are negative, additional investigations like small bowel evaluation might be needed. This comprehensive approach ensures no underlying condition is missed.
