Official title

Performance Characteristics of Immunochemical and Guaiac FOBT

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The objective of this study is to compare the performance characteristics or accuracy of different in-home screening tests for colorectal cancer (fecal occult blood tests), among patients without symptoms of colorectal cancer. Patients who meet study eligibility criteria and agree to participate in the study are asked to perform one guaiac and two immunochemical fecal occult blood tests at home prior to their colonoscopy. After the patient has completed and sent in the test kits, the patient then undergoes their previously scheduled colonoscopy. Accuracy and performance characteristics for each type of fecal occult blood test, including sensitivity, specificity, test positivity rate and positive predictive value for advanced colorectal neoplasia (advanced colorectal polyps) or colorectal cancer, will be estimated by comparing the fecal occult blood test results with the results of the colonoscopy.
