Claim:
1. A microfluidic apparatus comprising: a sample chamber; a sample separation unit which receives a sample from the sample chamber and separates a supernatant from the sample by using a centrifugal force, said sample separation unit including a linear shaped supernatant collecting portion and a precipitate collecting portion, wherein the precipitate collecting portion is wider than the linear shaped supernatant collecting portion; a testing unit comprising a detection chamber, in which a resultant of an antigen-antibody reaction between the supernatant, capture antibody or capture antigen, and a reaction buffer is received; and a first quality control chamber for identifying reliability in specimen detection, wherein the first quality control chamber is directly connected to the sample separation unit, wherein the first quality control chamber, directly connected to the sample separation unit, has a single point of entry from the sample separation unit and the first quality control chamber is wholly disposed more distally from the sample chamber than the supernatant collecting portion and the precipitate collecting portion of the sample separation unit.
