Abstract
The invention relates to a device and method for performing qualitative enzyme immunoassays. The device comprises at least one tube having antibody, antigen or hapten attached to an internal surface thereof. A first syringe is connectable to a first end of the tube or tubes and supplies a flow of test liquid therethrough. A second syringe having a two piston arrangement is connected to the tube so as to allow a first wash solution followed by an enzyme conjugate solution to be flowed therethrough. Finally a third syringe, also having a two piston configuration, is connected to the tube so as to allow a second wash solution followed by an enzyme substrate and metabolite indicator solution to be flowed therethrough.
