[The analysis of synovial fluid: clinical significance of derived results].

The review presents modern data concerning characteristics of drawing of synovial fluid and also informativeness of its particular indices for resolving main clinical differential diagnostic task namely - selection group of septic and micro-crystal arthritis. It is demonstrated that minimal generally available span of analysis of synovial fluid is to include: finding number of leukocytes (threshold level for diagnostic of septic arthritis is 50 000 - 100 000 kl/mkl) and percentage of ploymorpho-nuclear cells (threshold level is 90%); analysis of content of crystals, Gram's stain and culture analysis of synovial fluid using light microscopy; and all this with mandatory registration of clinical data. The common evaluation of content of glucose and protein in synovialfluid is not enough informative.
