TEST MICROCIRCUIT AND METHOD OF ITS MANUFACTURING Russian patent published in 2024 - IPC G01N37/00 G01N21/78 

FIELD: test equipment; diagnostics.

SUBSTANCE: test microcircuit comprises a first layer on one side of the surface and a second layer on the other side of the surface. First or second layer has a section A for receiving liquid. First layer has at least a detection confirmation section B. Second layer has at least a liquid distribution section D adjacent to the detection confirmation section B and a liquid flow channel E connected to the liquid distribution section D. Test microcircuit is designed so that when the test liquid falls on the liquid receiving section A, the test liquid is distributed in a given order by capillary action to achieve detection confirmation section B. From the surfaces of the first layer and surfaces of the second layer, at least surfaces of material M, different from the liquid receiving section A, are sealed with a film.

EFFECT: possibility to suppress non-uniform color and to perform quantitative assessment in a simple way regardless of the amount of the tested liquid.
