Abstract
Methods and apparatus for detecting cell-bound and soluble antigens in a biological sample are described. The method comprises forming complexes of at least one antibody-coated bead and at least one antigen in a solution, placing the solution in a magnetic field such that the formed complexes levitate in the solution at a particular height, and determining at least one characteristic of the antigen in the complexes based, at least in part, on an image of the complexes showing the magnetic levitation height.
