Abstract: A sequential flow analysis tool comprising a microfluidic device having a fluid path defined within a substrate between an input and an output is described. The device includes a capture chamber provided within but offset from the fluid path, the capture chamber extending into the substrate in a direction substantially perpendicular to the fluid path such that operably particles provided within a fluid flowing within the fluid path will preferentially collect within the capture chamber.

Abstract: The invention relates to a method of screening a patient to identify and quantify risk of colorectal cancer, and thereby identify patients suitable for further invasive investigation such as a colonoscopy. The method employs auto-antibodies that are shown to correlate with colorectal cancer risk method and involves of assaying a biological sample from the individual for a combination of a plurality of biomarkers selected from SEQUENCE ID NO's: 1 to 12, where the combination of biomarkers is chosen such that detection of all biomarkers in the patient correlates to at least a 50% risk of the patient being positive for colorectal cancer. Detection of all of the combination of biomarkers indicates that the patient should undergo a colonoscopy. Kits for performing the method of the invention are also provided.
