Fecal Immunochemical Testing (FIT) with bleeding in my mouth?

Fecal Immunochemical Testing (FIT) is said to "only detect blood from the lower intestines". Can it affect the test results if I have some bleeding in my mouth, some of which is swallowed? If not - how does it do the trick of distinguishing between different bloods?

Hello and welcome to EHF !

I went through your query and i want you to know that fecal occult blood test May detect the presence of blood in stools in order to have it localised, there are more invasive and specific test like endoscopy or radiolabelled RBC scans to find out the exact location of the bleed.

Take care
