Abstract
On the stand point of user and regulatory authority, researchers on microfluidics should emphasize not only the merits, but also important considerations from the view point of science and technology. The items like viscosity of patient sample and adsorption of the analyte on the inner walls, etc. should be taken into account and examined experimentally for the national guideline of practical medical uses. The considerations on microfluidics using patient serums of which liquid properties depend on individuals were evaluated. As a result, it is found that the effects of adsorption of the anaylte, and viscosity of patient sample are different from the conventional macroscale, and dependencies of blood sampling part should be no need to be taken into consideration in case of CRP. Standardization of the guideline for microfluidics is proposed in comparison with the conventional ones.
