Zusammenfassung:An exosome to be analyzed having a first bead and a second bead bound thereto is collected from a buffer fluid containing the exosome to be analyzed having the first bead and the second bead bound thereto. A first antibody that specifically binds to a first antigen associated with a first disease is fixed to a surface of the first bead. A second antibody that specifically binds to a second antigen associated with a second disease is fixed to a surface of the second bead. The first bead is separated from the exosome, and the exosome having the second bead bound thereto is collected. The exosome having the second bead bound thereto is dissolved, and the second bead and an inclusion of the exosome are collected (S19 and S20). The inclusion of the exosome is analyzed (S21), and the number of second beads is counted (S22).
