Equine synovial fluid analysis

Abstract

The most important application for synovial fluid (SF) analysis in the horse is in the diagnosis of synovial sepsis. Misdiagnosis of synovial sepsis is costly, and SF analysis makes correct diagnosis more likely, although far from certain. The precision of diagnosis may be increased with polymerase chain reaction analysis for detection of bacterial DNA in SF and with assays for various enzymes and cytokines. These tests are currently not widely available, however, and routine SF analysis remains of prime importance in diagnosis.
