PROBLEM TO BE SOLVED: To provide a new cancer / rheumatic test / diagnosis method, diagnostic agent and the like. SOLUTION: The present invention performs tests and diagnoses relating to cancer and rheumatism by detecting CD166 in body fluids such as blood and joint synovial fluid. CD166 is detected in the blood of cancer patients, and the detected amount correlates well with the presence / absence / size / loss of tumor, so that it can be used as a good humoral marker in cancer examination / diagnosis. Since CD166 was specifically detected in the synovial fluid of rheumatoid arthritis model animals, it can be used as a humoral marker for testing and diagnosis of rheumatism, such as the presence of rheumatism, the degree of progression, and the prognosis. Useful. [Selection] Figure 3 |
