Abstract: A tip for use in an optical detection system to analyze an analyte in a fluid sample drawn into the tip, using light reflected from a detection surface inside the tip that the analyte binds to, comprising a first detection surface and a second detection surface located in a same flow path with no controllable valve separating them, wherein the first and second detection surfaces have different surface chemistries.
