Screening for familial colorectal cancer with a sensitive immunochemical fecal occult blood test: For the manual FITs, specificity ranged from Quality and the college of American pathologists. Higher fecal immunochemical test cutoff levels: Samples spiked with human blood and control samples are sent to labs for testing, results are sent back to the proficiency testing program, and then summarized.
