ABSTRACT OF THE DISCLOSURE A method of making a multilayer analytical test element comprising providing a plurality of layers at least one of which is responsive to detect a ligand in a liquid sample, or to detect the ligand binding capacity of the sample, and at least one other layer that is fusible when subjected to sonic energy, arranging said plurality of layers one on top of the other together to form a composite blank of said layers, subjecting said composite to ultrasonic or laser energy to cut said composite to the desired dimension of the test element and to simultaneously weld said plurality of layers at the edges thereof, said energy softening and fusing said fusible layer to thereby bond said plurality of layers together.
