Additional Information
The Synovasure™ PJI test was developed specifically for the diagnosis of periprosthetic joint infection (PJI). Synovasure™ PJI is a laboratory developed test (LDT) for the detection of infection in the synovial fluid (joint fluid) of patients experiencing pain and/or inflammation in a joint. Synovasure™ is a panel of tests. The panel capitalizes on the diagnostic characteristics of alpha-defensin, and also includes an adjustment for samples with significant amounts of bloody contamination or hemolysis. Furthermore, the inclusion of a synovial fluid CRP test in the Synovasure™ PJI panel provides for the identification of samples that are most likely to represent false positive results due to confounding conditions such as metallosis. Synovasure™ PJI maintains its diagnostic performance even among patients with systemic inflammatory diseases, patients on antibiotics and patients experiencing the effects of metal products.
