Can tomato sauce cause a positive fecal occult test? i ate meatballs with red pasta sauce for the last two nights and i tested positive on the fit test today?

No. Food items do not cause a false positive FIT test. Positive FIT tests indicates bleeding in the colon/rectum. It would be prudent to discuss it with your doctor. Food items can cause a false positive guaiac test.
