FOB (Fecal Occult Blood) serves as an early warning sign for colorectal cancer and other gastrointestinal diseases. A sample of approximately 50mg, collected from at least 5 different parts of the stool, is required for testing. Each year, over one million patients worldwide suffer from gastrointestinal bleeding and need early screening.
