ABSTRACT:
The present invention relates to a method for passively determining the application of a sample fluid on an analyte strip using measurement of ambient light passing through the strip. Sample fluid, such as whole blood, is applied to a reagent matrix and the amount of ambient light transmitted through the matrix is periodically measured both before and after application of the sample fluid. A step increase of the transmitted light reading occurs after hydration of the strip, and the occurrence of this step increase is used to start a predetermined incubation period. At the expiration of the incubation period, another light transmission measurement is made which is indicative of an analyte concentration in the sample fluid (such as glucose concentration in a whole blood sample).
