Fecal immunochemical test

What is FIT?

Fecal immunochemical test (abbreviated as FIT or iFOBT) is used for colorectal cancer screening by detecting human hemoglobin on the surface of stool.  …

How FIT is performed in colorectal cancer screening?

30+ years, 45+ countries

Eiken Chemical launched sales of fully automated quantitative FIT analyzer in 1989. Since then, we have been developing our product “OC-SENSOR” for 30 years worldwide. It is now used in more than 45 countries. We have accumulated many experiences of participating in FIT programs, from national screening  to testing at local clinics.
