Medical professionals use gout microscopes assembled specifically for identifying gout or CPPD (pseudo-gout) crystals suspended in synovial fluid. Gout is a kind of arthritis that occurs when uric acid builds up in blood and causes joint inflammation. Gout is diagnosed by taking synovial fluid from the infected joint in the process of arthrocentesis. Lab technicians prepare a wet smear on a microscope slide with the fluid and use polarized microscopy to determine the presence of sodium urate crystals (gout) or calcium pyrophosphate dehydrate or CPPD within the fluid. CPPD crystals are small rods, squares, or rhomboids and are usually harder to identify without a gout or polarized light microscope. Polarizing filters can be easily adjusted when using the gout microscope. The beam splitter sends light directly up to the camera to capture images. The Meiji MT9520 Binocular Gout microscopes, the Meiji MT9530 Trinocular Gout microscopes and the Meiji MT9540 Ergonomic binocular Gout microscopes include Meiji Techno's Infinity Corrected Optical System. These microscopes are used for identification of crystals present in body fluids. Contact Microscope World with any questions you have about a specific gout microscope setup.
