If children suffer from viral enteritis or bacterial enteritis, there will be inflammatory exudation of the tiny blood vessels in the intestine, causing children to have a positive fecal occult blood test. 2, caused by dietary factors. If a child eats green leafy vegetables, duck blood, pig blood and other blood products, the stool occult blood test will also be positive. Therefore, when testing children’s stool occult blood, try to do not eat the above food before the test, otherwise it will cause a false positive.
