OctavaColon Blood Tests OctavaGold and OctavaSilver - Blood Tests for the Help in Diagnosis of Colon Cancer Clinical Study Protocol

The OctavaColon tests are qualitative plasma tests that are indicated to people above 18 years of age suspected with colon abnormality. The blood tests will provide additional information to the doctor in the course of colon cancer diagnosis for both normal population and high risk population

The clinical objective of this study is to develop two antibody-based blood tests for additional information during colon cancer diagnosis -

1. Highly specific (OctavaGold) - provides additional information to doctors during evaluation of normal population.
2. Highly sensitive (OctavaSilver) - provides additional information to doctors during evaluation of high risk population.

The study will be considered successful it can achieve at least one of the following sets of performances -

1. For the OctavaGold - 95% specificity with at least 50% sensitivity.
2. For the OctavaSilver - 95% sensitivity with at least 50% specificity. The biological objective of this study is to find the best set of antigens, that when combined with the appropriate algorithm will support each of the above clinical objectives
