Abstract: A sample test method, microfluidic device, and test device efficiently and accurately compensates for interference of an interfering substance present in a sample using optical measurement without addition of a separate reagent for detecting the interfering substance. The sample test method includes: measuring an optical characteristic value of a target substance present in a sample; measuring an optical characteristic value of an interfering substance present in the sample; and determining a concentration of the target substance for which interference of the interfering substance is compensated for based on the optical characteristic value of the interfering substance.

Abstract: Disclosed herein are a reactor, a test apparatus, and a test method, which measure, when a material included in a sample acts as an interfering material with respect to estimating a concentration of a target material, a concentration of the interfering material, and correct an estimated concentration of the target material based on the concentration of the interfering material, thereby improving the reliability and accuracy of the concentration of the target material. The reactor includes: a target material detecting chamber in which a first reagent that includes a first material that is activated by a target material is contained; a first material detecting chamber in which a second reagent that includes the target material is contained; an inlet hole into which a sample is injected; and a channel configured to connect the inlet hole, the target material detecting chamber, and the first material detecting chamber to each other.

Abstract: Provided is a microfluidic apparatus including: a microfluidic structure for providing spaces for receiving a fluid and for forming channels, through which the fluid flows; and valves for controlling the flow of fluid through the channels in the microfluidic apparatus. The microfluidic structure includes: a sample chamber; a sample separation unit receiving the sample from the sample chamber and separating a supernatant from the sample by using a centrifugal force; a testing unit receiving the supernatant from the sample separation unit for detecting a specimen from the supernatant using an antigen-antibody reaction, and a quality control chamber for identifying reliability of the test.
