Abstract: Biomarkers are used in compositions, combinations, systems, and methods for diagnosing, staging, and monitoring and/or treatment of osteoarthritis. The biomarkers discriminate osteoarthritis from rheumatoid arthritis, crystalline arthritis, septic arthritis, and/or traumatic injury, and can be used in a differential diagnosis of joint pain and/or joint inflammation.

Abstract: The invention provides methods and systems for detecting a biomarker in a synovial fluid wherein the system also includes a control to ensure that the test sample is indeed synovial fluid. The biomarkers and the control for synovial fluid can be identified using proteomic methods, including but not limited to antibody based methods, such as an enzyme-linked immunosorbant assay (ELISA), a radioimmunoassay (RIA), or a lateral flow immunoassay.
