A method for determining a concentration of an analyte in a subject includes irradiating a part of the subject with electromagnetic radiation, wherein a part of the subject comprises biological molecules arranged to absorb the electromagnetic radiation and to emit fluorescence in response. The method also includes measuring fluorescence emitted to obtain data representative of a fluorescence decay. The method further includes processing the data to determine one or more feature points associated with the fluorescence decay and to generate one or more feature vectors based on the one or more feature points, and applying the one or more feature vectors to a regression model for the analyte to determine the concentration of the analyte. Also provided is a system for determining a concentration of an analyte in a subject, as well as a measurement device for facilitating determination of a concentration of an analyte in a subject.
