Synovial Fluid Crystal Analysis

Quality control of synovial fluid crystal identification.

OBJECTIVE To establish a quality assessment programme for the diagnosis of crystal arthropathies by synovial fluid (SF) microscopy. METHODS Three or four cytocentrifuge slides prepared from suitable patient SF specimens were distributed to 25-47 predominantly Finnish clinical laboratories once a year. Sodium urate crystals were included in every survey. RESULTS Returns for the years 1989-19...

[Synovial fluid analysis].

At present, the study of the synovial fluid (SF) is a tool that is used frequently in specialized laboratories because it allows the establishment of diagnosis of crystal associated arthropathies, supports the diagnosis of septic arthritis and helps establish other rheumatologic diagnoses such as monoarthritis or joint effusion. The complete study of the SF includes the following analyses: 1. M...

Synovial perfusion and synovial fluid solutes.

answer goes back to the cardinal signs of inflammation. The redness and heat of this state relate directly to increased local blood supply, and these critical findings cannot be examined systematically without accurate quantification of flow. Further, the imbalances of vascular permeability and tissue clearance that lead to tissue swelling cannot be evaluated usefully without an understanding o...

Synovial Fluid Mucin.

Synovial mucin, the characteristic component of synovial fluid, was first isolated in 1846 by Frerichs (1846), who precipitated it from joint fluid by addition of. acetic acid. Its high viscosity and peculiar chemical composition made it a subject of much interest. Frerichs realized that it was a complex of protein and carbohydrate components, but little -additional information was added until ...
