MULTI-LAYER TEST DEVICES AND METHODS OF ASSAYING FOR FRUCTOSAMINE

摘要

The present invention is directed to a multi-layer test device (10) and method for analyzing the concentration of fructosamine in a liquid sample. The multi-layer test device (10) has a buffer layer (14) containing a buffer having a pH value of at least 9 which is either superposed above or juxtaposed to an indicator layer (15) containing an indicator capable of being reduced by fructosamine. Supporting the buffer layer (14), the indicator layer (15), and any additional layers in the multi-layer device (10) is at least one support member (16) which optionally has a detection aperture (13) for analyzing the concentration of fructosamine on the indicator layer.
