Hypothesis
The study aims to compare the specificity and predictivity for cancer and adenomas of four faecal occult blood test methods.
Conclusion
The study found that 1-day immunochemical testing is almost as specific as 3-day guaiac testing, but 3-day immunochemical testing is not recommended due to low specificity.
Supporting Evidence
- The positivity rates for the tests were 4.8%, 5.6%, 8.4%, and 11.2% respectively.
- Colorectal cancer was detected in three subjects and adenomas in 15.
- Three-day specificity estimates for the tests were 96.1%, 96.0%, 93.8%, and 91.2% respectively.
Takeaway
This study looked at different tests to find hidden blood in poop to check for colon cancer. It found that some tests are better than others at not giving false alarms.
Methodology
Subjects performed two guaiac and two immunochemical faecal occult blood tests on three consecutive faecal samples.
Limitations
The study's low number of detected lesions limits sensitivity estimates.
Participant Demographics
The sample included 350 males and 436 females with a mean age of 55.8 years.
