1. A system for measurement of an analyte comprising:
a wearable electronic device and a remote device, the wearable electronic device comprising:
a camera configured to generate a video stream;
a first communication transceiver configured to transmit and receive communications to and from a second communication transceiver at the remote device;
a head-up display (HUD);
a first memory configured to store program instructions; and
a first processor operatively connected to the first communication transceiver, the camera, and the first memory, the first processor being configured to execute the program instructions;
the remote device further comprising:
a second memory configured to store program instructions; and
a second processor operatively connected to the second transceiver and the second memory, the second transceiver configured to transmit and receive communications to and from the first communication transceiver;
the wearable electronic device and the remote device being operatively connected to each other, wherein the first processor and second processor cooperate to execute the program instructions to:
identify test components in the video stream and provide guidance to the user via the HUD of required test components not detected in the video stream;
identify the application of a bodily fluid sample to a deposit site on a test strip based on the video stream;
activate a timer in response to confirmation of the application of the bodily fluid sample;
after a minimum period of time and before a maximum period of time from the activation of the timer, generating via the camera at least one image of the test strip including at least a portion of a measurement site, the at least one image being captured after guidance to the user via the HUD for positioning the test strip a predetermined distance and angular orientation relative to the camera;
analyze optical properties of at least a portion of the measurement site within the image to determine a level of an analyte; and
display the level of the analyte on the HUD.
