Several test options are available for colorectal cancer screening: Stool-based tests. Highly sensitive fecal immunochemical test (FIT) every year. Highly sensitive guaiac-based fecal occult blood test (gFOBT) every year. Multi-targeted stool DNA test with fecal immunochemical testing (MT-sDNA or sDNA-FIT or FIT-DNA)) every 3 years.
