An in vitro diagnostic card and method of construction thereof is provided. The card includes an intermediate layer having opposite faces with at least one channel extending through the faces. A translucent first layer is fixed to one of the faces of the intermediate layer and a translucent second layer is fixed to the other of the faces of the intermediate layer opposite the translucent first layer. The channel in the intermediate layer is substantially sealed off by the first and second layers. Further, an opaque material that is absorbent to laser beam energy bonds the intermediate layer to the first and second layers. |
