Alpha Defensin Lateral Flow Test for Diagnosis of Periprosthetic Joint Infection Not a Screening but a Confirmatory Test

摘要

Background: Determination of alpha defensin in synovial fluid has shown promising results for diagnosing periprosthetic joint infection (PJI). The purposes of our study were to assess the performance of alpha defensin lateral flow (ADLF) test for the diagnosis of acute and chronic PJI using 3 classification systems and to compare its performance with the synovial fluid leukocyte count.
