Short summary
Synovial pH, lactate, and glucose are established biomarkers for joint infection but are usually analyzed in central laboratories. In this prospective analytical agreement study, we evaluated whether blood gas analyzers can measure these parameters at the point of care. Blood gas analyzer measurements showed good to excellent agreement with laboratory reference methods, particularly for lactate and glucose, supporting their use for rapid diagnosis of native and periprosthetic joint infection.
