you should avoid eating red meat prior to testing

Explanation:

A fecal occult blood testing (FOBT) is a cost-effective, non-invasive method for colon cancer screening, which can be used in asymptomatic patients. The FOBT test is used to identify hidden blood in stool samples, which may be indicative of colon cancer and the presence of polyps in the colon/rectum. It has been shown that screening by FOBT can significantly reduce mortality from colorectal cancer. Two days before the FOBT test, it is imperative to avoid red meats and other foods (e.g., beets, carrots, cauliflower, cucumbers, grapefruit, broccoli, cantaloupe, etc), which might lead to false alarms.
