1. An apparatus comprising:

  • a plurality of adjacent reaction sites;

    a sample collection unit, for introducing a biological fluid, in fluid communication with the plurality of adjacent reaction sites;

    a plurality of reagent chambers, including a plurality of reagents, in fluid communication with said reaction sites,wherein each of said plurality of reaction sites comprise one or more reactants bound thereto for detecting an analyte; and

    a system of fluidic channels to allow said biological fluid and said plurality of reagents to flow in said apparatus;

    wherein at least one of said plurality of adjacent reaction sites is between two optical barriers, said two optical barriers comprise two non-linear channels configured to not allow photons to pass through the two non-linear channels and contaminate signals produced from the plurality of adjacent reaction sites;

    walls of the at least one reaction site comprise optically opaque materials so that light will not escape said at least one reaction site through said walls, andthe two nonlinear channels provide fluid communication between the plurality of adjacent reaction sites.
