ABSTRACT:
A device for collecting a specimen, including (a) a test vessel for containing a solution containing an immunocomplex, which is a complex as a result of an antigen-antibody reaction between a specimen and a magnetic-labeled antibody containing a magnetic micro-particle and an antibody fixed to the micro-particle, (b) an external magnetic field generating device for generating a magnetic field, preferably a gradient magnetic field and applying it to the solution in the test vessel to effect local concentration of the immunocomplex to a predetermined position, (c) a magnetic member for collecting the immunocomplex at the position of local concentration, and (d) a moving mechanism for achieving relative movement between the magnetic member and the test vessel.
