A FIT kit, short for Fecal Immunochemical Test, detects hidden blood in the stool, a possible indicator of cancer or precancerous conditions. You don’t need any special diet or preparation for this test. It’s non-invasive, private, and it can be done in the comfort of your home. FIT kits detect potential issues early when they’re most treatable. Early detection is key to survive cancer, and with a FIT kit, it’s easier than ever.
