ABSTRACT:
The present invention is directed to a multi-layer test device and method for analyzing the concentration of fructosamine in a liquid sample. The multi-layer test device has a buffer layer containing a buffer having a pH value of at least 9 which is either superposed above or juxtaposed to an indicator layer containing an indicator capable of being reduced by fructosamine. Supporting the buffer layer, the indicator layer, and any additional layers in the multi-layer device is at least one support member which optionally has a detection aperture for analyzing the concentration of fructosamine on the indicator layer. An additional support member having a sample aperture can be used. Where two support members are used the multi-layers are sandwiched between the first support member having a sample aperture and the second support member optionally having a detection aperture.
