1. A kit for detecting an antigen from which false positive signals are removed, comprising:
a substrate;
a capture antibody attachable onto the substrate and having a capture strand labeled with a fluorescent material;
a detection antibody having a detection strand labeled with a fluorescent material and complementary to some or all of a base sequence of the capture strand; and
a blocking strand having a base sequence capable of complementary binding to the capture strand or the detection strand to prevent the detection strand and the capture strand from complementary binding to each other.
