Beschreibung
Zusammenfassung:	A multilayer analytical element for detecting a ligand in or the ligand binding capacity of a liquid sample of the type having a reagent layer incorporating reagents which are responsive to the ligand in or the ligand binding capacity of the sample to give a detectable response, a radiation diffusing and blocking layer, and a support layer, the improvement wherein the radiation diffusing and blocking layer is (a) interposed between the reagent layer and the support layer; (b) impermeable to the ligand, reagents of the reagent layer, and products of their interreaction; and (c) inert to the ligand, reagents of the reagent layer, and products of their interreaction.
