Abstract
An apparatus and method for detecting the presence of anisotropic crystals within a biologic fluid sample is provided. The method includes the steps of: a) disposing the sample within a sample chamber in a sample layer having a height not greater than about fifteen microns (15μ); b) disposing the sample layer within the sample chamber between a polarizing filter and an analyzing filter; c) disposing the polarizing filter, sample chamber, and analyzing filter in a configuration relative to a light source such that polarized light passes through the sample, and subsequently impinges on the analyzing filter; and d) wherein polar orientations of the polarizing filter and the analyzing filter are such that the polarized light will not pass through the analyzing filter, and light passing through an anisotropic crystal disposed within the sample will pass through the analyzing filter and appear as a point of light.
