  • Detection of alpha defensins 1-3, human host response proteins, in synovial fluid of adults with a total joint replacement who are being evaluated for revision surgery
  • This test is not intended to be used to determine timing for reimplantation in 2-stage procedures
  • This test should only be used for patients with a total joint prosthesis
