Overview
Laboratory testing is usually normal among patients with colon polyps. However, some patients with colon polyps may have abnormal tests, including CBC and stool test, which is usually suggestive of gastrointestinal bleeding. They might present with anemia or positive fecal occult blood.
Laboratory Findings
- Laboratory testing is usually normal among patients with colon polyps.[1][2][3][4]
- Some patients with colon polyps may have abnormal tests, including CBC and stool test, which is usually suggestive of gastrointestinal bleeding.
- Laboratory findings consistent with the diagnosis of colon polyps include:
- CBC
- Anemia (normal hemoglobin - 12.1 to 15.1 g/dl for women and 13.8 to 17.2 g/dl for men)
- Stool test
- Positive fecal occult blood
- Positive fecal immunochemical test
- Positive stool DNA test
- CBC
