A method for measuring an analyte comprising: - identifying, with a processor, test strip in a video stream generated by a camera based on at least one registration mark associated with the test strip depicted in the video stream; - identifying, with the processor, application of a fluid dose to a deposit site formed on the test strip based on the video stream; - activating, with the processor, a timer in response to the identification of the application of the fluid dose; - generating, with an optical sensor, at least one optical measurement of a reagent located at a measurement site on the test strip; and generating, with the processor, a measurement of an analyte in the fluid dose based on the at least one optical measurement of the reagent only in response to the at least one optical measurement being generated after a predetermined minimum time period has elapsed subsequent to the activating of the timer and prior to a predetermined maximum time period elapsing subsequent to the activating of the timer, characterized in that the method further comprises: - identifying, with the processor, a vial in a video stream generated by a camera based on at least one of an outline shape of the test vial or at least one registration mark located on the vial depicted in the video stream; - identifying, with the processor, an opening of the vial in the video stream based on at least one registration mark located on a lid of the vial; and - identifying, with a processor, extraction of the test strip from the vial after the identifying of the opening of the vial in the video stream based on the at least one registration mark associated with the test strip depicted in the video stream. - identifying, with a processor, test strip in a video stream generated by a camera based on at least one registration mark associated with the test strip depicted in the video stream; - identifying, with the processor, application of a fluid dose to a deposit site formed on the test strip based on the video stream; - activating, with the processor, a timer in response to the identification of the application of the fluid dose; - generating, with an optical sensor, at least one optical measurement of a reagent located at a measurement site on the test strip; and generating, with the processor, a measurement of an analyte in the fluid dose based on the at least one optical measurement of the reagent only in response to the at least one optical measurement being generated after a predetermined minimum time period has elapsed subsequent to the activating of the timer and prior to a predetermined maximum time period elapsing subsequent to the activating of the timer, characterized in that the method further comprises: - identifying, with the processor, a vial in a video stream generated by a camera based on at least one of an outline shape of the test vial or at least one registration mark located on the vial depicted in the video stream; - identifying, with the processor, an opening of the vial in the video stream based on at least one registration mark located on a lid of the vial; and - identifying, with a processor, extraction of the test strip from the vial after the identifying of the opening of the vial in the video stream based on the at least one registration mark associated with the test strip depicted in the video stream. - identifying, with the processor, a vial in a video stream generated by a camera based on at least one of an outline shape of the test vial or at least one registration mark located on the vial depicted in the video stream; - identifying, with the processor, an opening of the vial in the video stream based on at least one registration mark located on a lid of the vial; and - identifying, with a processor, extraction of the test strip from the vial after the identifying of the opening of the vial in the video stream based on the at least one registration mark associated with the test strip depicted in the video stream.
