The application provides an automatic reading method and system for antibody identification results based on a vector space model, which comprises the following steps: constructing an antibody specificity vector model, mapping the antigen spectrum corresponding to each antibody specificity in an antibody identification pedigree table into an antibody specificity vector with a fixed dimension; mapping the reaction results of antibody identification of a serum sample to be tested into a to-be-tested vector through the antibody specificity vector model; calculating the similarity between the to-be-tested vector and the antibody specificity vector; and performing reading based on reading logic according to the similarity calculation results to obtain antibody identification results. The antibody identification results can be automatically read by calculating the vector similarity, the antibody identification can be realized quickly, accurately and standardly, and the work efficiency is improved significantly, and the manpower is liberated.

The application belongs to the technical field of biological medicine, discloses application of bone metastasis specific secreted protein DKK3 in early diagnosis of lung cancer bone metastasis, and specifically discloses application of a substance for detecting DKK3 in preparation of a product for diagnosing or early screening of lung cancer bone metastasis. The application discloses the relationship between secreted protein DKK3 expression and lung cancer specific bone metastasis for the first time, and verifies that secreted protein DKK3 is specifically highly expressed in serum samples of lung cancer bone metastasis patients and lung cancer bone metastasis cells, which indicates that secreted protein DKK3 can be used as a new lung cancer bone metastasis diagnostic marker, and can significantly distinguish lung cancer patients with bone metastasis from lung cancer patients with metastasis to other organs and healthy people.
