A positive EZ DETECT test means that there may be bleeding in the gastrointestinal tract. Benign conditions such as polyps, hemorrhoids or rectal fissures can cause bleeding that would cause a positive result. Most studies suggest that only 5 to 10 percent of those with positive tests will be diagnosed as having cancer. However, it is imperative that anyone with a positive test result sees a physician as soon possible to determine the cause of bleeding. TAKE THE TEST CARD TO YOUR PHYSICIAN. PLEASE DO NOT MAIL TO BIOAMERICA.
