摘要： A method for the determination of an analyte in a bodily fluid sample includes transferring a bodily fluid sample (such as a whole blood sample) to a sample chamber of an analytical test strip. The analytical test strip to which the bodily fluid sample is transferred has a substrate layer, an electroluminescent module disposed on the substrate layer and in optical communication with the sample chamber, and a fluorophore-containing photometric enzymatic reagent disposed within the sample chamber. In addition, the electroluminescent module is configured to emit light that facilitates a fluorescent chemical reaction sequence involving the fluorophore-containing photometric enzymatic reagent and the analyte. The method also includes exposing the fluorophore-containing photometric enzymatic reagent to the bodily fluid sample and to light emitted from the electroluminescent module such that photons are emitted from the fluorophore-containing photometric enzymatic reagent via a fluorescent chemical reaction sequence. Moreover, the method includes detecting the photons with a photodetector.
