A multiplex test system comprising: an article (10) that supports solid phase tests, said article comprising a rigid planar substrate (12) and comprising two or more different liquid containment regions (26, 28, 30), comprising each liquid-containing region at least one analysis region that can be optically interrogated, each analysis region having one or more binding partners associated with a substrate surface, where said binding partners bind to one or more analytes present in a sample in the liquid containment region (26, 28, 30), where for at least one liquid containment region (26, 28, 30), the one or more analytes are selected from the group consisting of antigen prostate specific (PSA), free PSA, complex PSA, pro-PSA and human kallikrein protein (hk2); and an optical device (36, 38) configured to deliver collimated light to illuminate an analysis region of the two or more liquid containment regions (26, 28, 30) and detect light from the analysis region. illuminated. |
