Fecal Occult Blood (5 Card)
The Fecal Occult Blood (5 Card) test measures the presence of hidden (occult) blood in the stool, which can be an early sign of various gastrointestinal conditions. Clinicians typically order this test as part of routine screenings for colorectal cancer, especially in individuals over the age of 50, or when there are symptoms such as unexplained abdominal pain, changes in bowel habits, or unexplained weight loss. The Fecal Occult Blood (5 Card) test is particularly useful because it can detect small amounts of blood that are not visible to the naked eye, allowing for timely diagnosis and intervention.
