METHOD OF DETERMINING THE CONCENTRATION OF AT LEAST ONE ANALYTE IN A BODILY FLUID

A method of determining the concentration of at least one analyte in a bodily fluid by using a mobile device (112) is disclosed, the mobile device (112) having at least one camera (114) and at least one ambient light detector (122), the ambient light detector (122) comprising at least one of an ambient light sensor (124) and an additional camera (126), the method comprising:i. performing at least one ambient light check (178), the ambient light check (178) comprising:i.1 using the ambient light detector (122) for determining at least one item of ambient light information; andi.2 determining if at least one validity criterion on the item of ambient light information is fulfilled;ii. if the validity criterion is fulfilled, determining the concentration of the analyte in the bodily fluid by evaluating at least one image of at least a part of at least one reagent test region (118) of an optical test strip (116) having a sample of the bodily fluid applied thereto, the image being captured by the camera (114) of the mobile device (112).Further, a mobile device (112), a kit (110), a computer program and a computer-readable storage medium is disclosed.
