METHOD FOR DETERMINING AN ANALYTE USING AN ANALYTICAL TEST STRIP WITH A MINIMAL FILL-ERROR VIEWING WINDOW

摘要

A method for determining an analyte (such a glucose) in a bodily fluid sample includes introducing a bodily fluid sample (e.g., a whole blood sample) into a sample-receiving chamber of an analytical test strip. The method also includes verifying that the bodily fluid sample has filled at least a working portion of the sample-receiving chamber by user visual observation of the working portion through a first portion of a top layer of the analytical test strip, while an opaque second portion of the top layer precludes user visual observation of a non-working portion of the sample-receiving chamber. Thereafter, in the method, the concentration of analyte in the bodily fluid sample is determined only if during the verifying step the user has verified that the bodily fluid sample has filled the working portion.
