...the study compared three fecal occult blood tests: InSure FIT, OC FIT-CHEK and Hemoccult II SENSA (a highly sensitive guaiac FOBT), in 1,006 asymptomatic patients, aged between 50 and 75 years, who also received a screening colonoscopy. The authors reported that “InSure FIT was statistically significantly more sensitive than both the OC FIT-CHECK and Hemoccult II SENSA.”
Ref: Pivotal study reports InSure® FIT™ offers superior sensitivity for colorectal cancer screening. InSure FIT more sensitive than OC FIT-CHEK and Hemoccult II SENSA for detecting advanced colorectal cancer
