Chemiluminescent analytical device
First Claim
1. A test device for determining an analyte in a sample comprising at least one layer incorporated with a first reagent system responsive to the presence of said analyte to produce a reaction product and at least one luminescent layer having a second reagent system responsive to the presence of said reaction product to produce luminescence, and in which there is a pH gradient between the first reagent system layer and the luminescent layer.

Abstract
A device, method of making the device and method for determining a constituent in a sample by production of luminescence are disclosed. More particularly, there is provided a test device for determining an analyte in a sample comprising unitary solid carrier means incorporated with a first reagent system responsive to the presence of said analyte to produce a reaction product and a second reagent system responsive to the presence of said reaction product to produce luminescence. The test device can further comprise a photoresponsive layer physically associated with said carrier means and responsive to light produced by the chemiluminescent system.
