Synovial fluid is normally a thick, straw-colored liquid found in small amounts in joints. How the Test is Performed A sample of synovial fluid is needed for this test. The tests help diagnose and treat joint-related problems. Bacterial cultures require 2-3 mL of fluid in a yellow top tube. Synovial fluid analysis is a group of tests that examine joint (synovial) fluid. Specimen requirement for cell count and differential is 1 mL of synovial fluid transferred to a lavender top (EDTA) tube. They are associated with degenerative arthritis. Cholesterol crystals may also be observed as bright square or rectangular plates. Synovial fluid from patients with JIA is usually inflammatory (Table 15-4). This polarization pattern is the opposite of monosodium urate crystals. Because one of the key elements of synovial fluid analysis is examination. With polarized light, they are weakly birefringent and appear yellow when aligned with the compensator axis. They differ from monosodium urate in that they form very small rhomboids, short rods, or rectangles. Examination of synovial fluid is the most accurate way to exclude. They are smaller than cholesterol crystals and lack the corner notch. Distinguishing Inflammatory versus Noninflammatory Joint Disease by Features. Calcium pyrophosphate crystals are present in chondrocalcinosis. Calcium pyrophosphate dehydrate crystals usually appear as rhomboids and tend to be small, measuring between 1 and 20 um. Urate crystals are mainly needle-shaped and strongly doubly refractile, and may be found within leukocytes. Synovial fluid (SF) accumulates in the joint cavity in different conditions this review outlines the data from those analyses that help in their differential and definitive diagnosis. Monosodium urate crystals are seen in gouty fluids. Crystal identification aids in the diagnosis of joint disease. Synovial fluid aspiration and analysis is a necessary therapeutic and diagnostic procedure useful. 90% of patients with acutely inflamed joints. The patients chart should undergo a thorough review prior to undergoing arthrocentesis to ensure the patient has no significant allergies to any medication, material, or chemical that may be in use during the procedure.
