The C-Reactive Protein (CRP) test is a quantitative in vitro laboratory developed test (LDT) to measure CRP in synovial fluid of patients experiencing pain and/or inflammation in a joint. This assay is a component of the multi-analyte diagnostic algorithm used to aid in the detection of periprosthetic joint infection (PJI). The measurement of CRP in synovial fluid is used in conjunction with other biomarkers as a component of the Synovasure® Comprehensive PJI Panel to aid the diagnosis of PJI.
Panels Included In
Available in New York State?
Yes. The Synovial Fluid CRP test is available as part of the Synovasure® Comprehensive PJI Panel and Synovasure® Alpha Defensin for PJI test options.
Periprosthetic joint prior to implant removal
Note: Performance on specimens from other anatomic locations is not defined. Non-intraarticular joint fluid will be tested if Zimmer Biomet is participating in a clinical study.
