摘要:
Provided is a microfluidic device that can automatically perform various types of biological blood analysis. In the microfluidic device, a specimen is centrifugally separated and the centrifugally separated specimen is diluted into various dilution ratios. Also, at least two reagents that are required for one reaction and that need to be separately stored are stored in separate chambers, and they are mixed when a reaction is needed. Thus, various conventional blood analyzing reagents can be used as they are or after being minimally processed in the microfluidic device.

Provided are a method of measuring a concentration of a component in a biochemical sample such as serum, and a method of estimating the reliability of a test result using the method. The method of measuring a concentration of a component includes: preparing plural standard samples having at least one common component which has varying concentrations; measuring absorbances of the component in the standard samples at each of the concentrations for plural light beams having different wavelength bands; determining a regression equation of a relationship between the concentration of the component and the measured absorbances at plural wavelength bands; and applying the regression equation by measuring absorbances at the plural wavelength bands of the biochemical sample and applying the measured plural absorbances of the biochemical sample to the regression equation to calculate the concentration of the component.
