| Abstract: Examples are described including measurement systems for conducting
competition assays. A first chamber of an assay device may be loaded with
a sample containing a target antigen. The target antigen in the sample
may be allowed to bind to antibody-coated beads in the first chamber. A
control layer separating the first chamber from a second chamber may then
be opened to allow a labeling agent loaded in a first portion of the
second chamber to bind to any unoccupied sites on the antibodies. A
centrifugal force may then be applied to transport the beads through a
density media to a detection region for measurement by a detection unit. |
