The detection of occult blood in stool using Hemoccult SENSA, a more sensitive and readable test than regular Hemoccult, is a highly effective method for detecting bleeding associated with colorectal cancer and adenomas.

Prospective, randomized controlled clinical trials extending for up to 18 years have demonstrated that the Hemoccult products are effective in detecting occult blood in stool as an early indication colorectal cancer.

In clinical trials that enrolled over 339,000 individuals, mortality from colorectal cancer was reduced up to 33% when fecal occult blood tests were performed annually^3-5 and 15-21% when performed biennially6. The program sensitivity for detecting colorectal cancer when Hemoccult was performed annually was 90%.^7,8

Hemoccult SENSA Single Slides are convenient for use when single fecal specimens are collected for routine in-office gastrointestinal screening.

Hemoccult II SENSA Slides are designed so patients can collect serial specimens at home from bowel movements over three days. After the patient prepares the Hemoccult II SENSA test, it may be returned in person or by mail (using the Hemoccult Mailing Pouch) to the laboratory, hospital or medical office for developing and interpretation.

The Hemoccult SENSA tests consist of two main components:

1.	Hemoccult SENSA Slides (Test Cards) containing guaiac paper
2.	Hemoccult SENSA Developer, a developing solution containing a stabilized mixture of less than 4.2% hydrogen peroxide and 80% denatured ethyl alcohol and enhancer in an aqueous solution.

Polyps and cancer may bleed intermittently. Hemoccult II SENSA triple slide products are designed so patients can collect serial specimens over three days. This increases the probability of detecting hidden blood from polyps and cancer.
