Synovial Fluid Crystal Analysis

Abstract

Synovial fluids comprise less than 5% of the fluid analyses performed by the typical laboratory. The microscopic technique used in crystal analysis can be challenging for the inexperienced technologist. This article discusses the theory of crystal detection and the operation of a polarizing microscope with a first-order red compensator. It provides tips on procedures that will enhance the detection and identification of crystals in synovial fluids.
