Electrophoresis is used to identify presence of a target compound in a patient sample based on a charge state of the compound and a label. The charge state of the compound correlates to a total net charge of a binder conjugated to the compound. The bound complex or “bound complex” with the label is then applied to the electrophoresis substrate. An electric potential is applied to the substrate for a time period and causes the labeled bound complex to migrate toward the electrode with opposite charge of the labeled bound complex at a migration velocity to form a migration pattern over the time period. At some time during or at the end of the time period, the labeled bound complex produces a bound complex band as a result of its migration across the substrate. The presence of the compound is identified based on the labeled bound complex band and one or both of the migration pattern and the migration velocity.
