Analysis of synovial fluid

Analysis of synovial fluid is of extreme importance for diagnosis and treatment 
of joint diseases. It is divided into general and 
special analysis. Analyses regarding colour, quantity, viscosity, transparency and formations of
 mucinous clots in synovial fluid are classified
 among general investigations. Less complicated microscopic investigations, such as those 
regarding number and differential picture of
 leucocytes, also belong to this group. In numerous cases, differential diagnostic problems may 
be clarified by previously mentioned analyses, which are quite rapid (especially in cases of
 suspected acute joint infection, arthritis caused
 by crystals, blood effusion into a joint and similar). Valuable data regarding the type of the joint
 disease can be obtained by special analyses
 (microbiological, immunoserological, biochemical) 
and examination of synovial fluid for crystals 
(polarising microscopy). Special analysis is an 
important guide in the planning of treatment.
