Pro Advantage Single Slide Fecal Occult Blood Test 100/bx
ProAdvantage Fecal Occult Blood Test is a rapid, stool test used to detect the presence of microscopic blood (hidden GI bleeding) in the feces. Occult blood tests are particularly important for early detection of colorectal cancer because 80% of patients with this disorder test positive. This asymptomatic occult bleeding may not be visible with the naked eye. Rapid results, convenient and CLIA waived and FDA 510(k) cleared.

Fecal occult blood tests help to determine the presence of occult blood (hidden GI bleeding) and to distinguish between true melena and melena like stools. Certain medications, such as iron supplements and bismuth compounds, can darken stools so that they resemble melena.
The guaiac fecal occult test Hemoccult Sensa has greater sensitivity for cancer and advanced adenomas than does the Hemoccult II. Both tests produce a blue reaction in a fecal smear if occult blood loss exceeds 2 to 3 mL in 24 hours. A newer test called the fecal immunochemical test (FIT) detects human globin, a protein that --along with heme--constitutes human hemoglobin. This makes the FIT more specific for human blood than guaiac-based tests, such as Hemoccult SENSA. The FIT is morespecific for lower GI-type bleeding, improving its specificity for detecting colorectal cancer. Some FITs also require fewer samples and less direct handling of stool.
