Fecal Occult Blood Test (FOBT)
A fecal occult blood test checks for hidden blood in three consecutive stool samples. One clinical trial in the United States reported a 33 percent reduction in
colorectal cancer deaths and a 20 percent reduction in colorectal cancer incidence among people offered an annual FOBT. Population-based trials in Europe have demonstrated that screening every other year reduced colorectal cancer deaths by 15 to 18 percent.
