There are also tests that provide you an analysis without having to mail your sample to a lab. Some will require a prescription; consult with your physician. An example of such a test is the Second Generation FIT® Colon Cancer Test which provides a kit with a solution to conduct a fecal immunochemical test that, according to the company, is "considered a preferred screening method for colorectal cancer detection by the U.S. Preventive Services Task Force" and other medical organizations. Results will appear in one to three minutes. Research suggests that at-home tests are generally reliable.
