Abstract: Two different antibodies that specifically bind to tau protein or phosphorylated tau protein are used. One of the two different antibodies is a first antibody immobilized on a support or labeled with a molecule capable of binding to the support, and the other of the two different antibodies is a second antibody labeled without being immobilized on the support. The tau protein includes an N-terminal domain, a C-terminal domain, and an intermediate domain located between the N-terminal and C-terminal domains. Epitopes recognized by the first and second antibodies are each an amino acid sequence contained in the intermediate domain or an amino acid sequence contained in the N-terminal domain. One of the first and second antibodies is first subjected to an antigen-antibody reaction with the blood sample, and the other of the first and second antibodies is subsequently subjected to an antigen-antibody reaction with the blood sample.
