<p>The calibration aid according to the application may be assembled as follow. First, the standard reference substance (6) is prepared by dissolving ICG dye and albumin protein in water. Then, the carrier sheet (1) of fleece material is soaked therein and dried. After drying the carrier sheet (1), a thin well defined layer of protein bound dye is present at the surface of the fleece material. The carrier sheet (1) and the backing sheet (2) are laminated into a plastic card. For this, the plastic layers (4a,4b) may be laminated tightly together in the framing region (5) for example by welding or by use of adhesive.
