Yes frm dietary heme: You can have false positive reading that is caused from dietary heme ( from red meat)- thus you should avoid red meat , poultry, fish, some raw vegetables (turnips, horseradish, etc.), and vitamin, aspirin, nsaids - 3 to 5 days prior to checking the fecal occult blood test. In addition, repeating the test- 2 slides each time from 3 separate bm-is recommended to increase sensitivity and accuracy.
