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.
