Abstract
A method for identifying a result of a test carried out from a fluidic sample, the fluidic sample being contained in a translucent container, the container being positioned on an area of interest of the container and opposite a dedicated area of the support. Ranges of reference colorimetric values and geometric references are printed on the support which also includes calibration colorimetric values printed in the at least one color calibration area.

A method for identifying a result of a test carried out from a fluidic, sample, the fluidic sample being contained in a translucent container and the method comprising the following steps:
- provision of a support for the container containing the fluidic sample;
- positioning of the container opposite a dedicated area of the support;
- capture of a digital image of the support and of the container positioned on the support;
- determination of an area of interest of the container occupied by at least one portion of interest of the container in the digital image;
- extraction of a colorimetric information relating to the area of interest of the container in the digital image, so that said extraction is configured to eliminate an artifact present in the area of interest of the container;
- identification of the result of the test based on the analysis of the colorimetric information.
