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.

Sample test method, microfluidic device, and test device

Disclosed herein are a structure for optical analysis that is capable of optically analyzing a small amount of a sample and an ink composition for manufacturing the same. A structure for optical analysis includes a support and an ink structure coupled to the support and configured to form a chamber on one surface of the support. The ink structure includes a first ink structural component configured to form a body of the ink structure and a second ink structural component formed at a lower portion of a side surface of the first ink, such that the first ink structural component and the second ink structural component have different slopes with respect to a direction of a center of the chamber.
