Abstract: A system and method for characterizing viral infection in a human or animal patient, in particular coronavirus infection, involves providing fluid from a body sample of the patient to a biosensor array comprising an array of sensor elements bearing one or more antigens of a target virus, to perform assays. The assays comprise a first group to sense a collective immune response and a second group to selectively sense an immunoglobulin IgM response and an immunoglobulin IgG response to the antigens. The collective immune response detects presence of the target virus and the levels of the immunoglobulin IgM and IgG response are compared to determine a stage of the immune response to the target virus.
