The scientific work presents aspects regarding the functioning and modeling of a lab-ona-chip microfluidic device used for blood tests where the leukocyte count is followed, which informs us about the state of the immune system. Aspects regarding the stage of development of lab-on-a-chip devices are presented, extremely useful in the current conditions of the pandemic due to the rapidity of providing analysis results and the opportunity to perform certain determinations, impossible with current conventional equipment. AutoDesk INVENTOR Professional software was used to model the device and COMSOL Multiphysics software was used to simulate the finite element operation of a circuit variant, as well as its geometric optimization. Research has been carried out on the components of the device, such as the pressure system and the counting system. The conditions for the execution of the device on a millimeter silicon wafer were created using photochemical microtechnologies.
