Abstract:
A biomedical measuring device, such as a test strip, has a simple structure, by which analyte can be measured easily using a small amount of specimen. In embodiments, the test strip generally includes a plastic first film layer having structure defining an aperture for retaining the reacting components, a porous membrane coupled to an inner-facing surface of the first film layer and configured to reduce background signal, an absorbent pad coupled to the porous membrane and first film layer to sandwich the porous membrane therebetween, the absorbent pad being configured for rapid absorption, and a plastic second film layer coupled to the absorbent pad, the second film layer being configured to provide a barrier to prevent liquid from leaking out of the test strip during use. The test strip can be easily used with an optical sensing device coupled to or containing an analyzer device (or reader device) for quickly detecting and measuring the analyte concentration. In a particular embodiment, the analyte comprises glycated hemoglobin or HbA1c, and the optical reader device is configured to determine HbA1c concentration.

Claim (Index 1):
A test strip assembly for testing a blood sample in which red blood cells containing both glycated and non-glycated hemoglobin from the blood sample have been precipitated out from the blood sample using a reagent, the test strip assembly comprising:\n a first film layer, the film layer including structure defining an aperture; a porous membrane coupled to the first film layer and in fluid communication with the aperture, wherein the porous membrane is configured to retain the precipitated glycated and non-glycated hemoglobin particles and red blood cells from the blood sample, while allowing a remaining blood sample to pass through the membrane; and a second film layer coupled to the porous membrane such that the porous membrane is positioned between the first film layer and the second film layer, wherein the test strip assembly is configured to be positioned within an optical sensing device to determine, by analyzing a retained blood sample retained on the porous membrane, a percentage of glycated hemoglobin of total hemoglobin in the blood sample.
