Shop - Synovial Fluid for Crystals

Description

1. Synovial Fluid for Crystals Test: A diagnostic procedure that involves analyzing synovial fluid, the lubricating fluid found in joint spaces, to identify the presence of crystals, which can indicate specific types of arthritis or joint disorders.
2. Purpose: This test is primarily used to diagnose crystal-induced arthropathies such as gout and pseudogout. The identification of crystals in the synovial fluid can help differentiate between various types of inflammatory arthritis.
3. Sample Collection: A synovial fluid sample is obtained through arthrocentesis (joint aspiration), where a needle is inserted into the joint space to collect fluid. Proper aseptic technique is crucial to avoid contamination.
4. Types of Crystals Analyzed:
   • Monosodium Urate Crystals: Associated with gout, these needle-shaped crystals typically indicate hyperuricemia and inflammation.
   • Calcium Pyrophosphate Dihydrate (CPPD) Crystals: Associated with pseudogout, these rhomboid-shaped crystals can indicate the presence of calcium pyrophosphate deposition disease.
5. Microscopic Examination: The synovial fluid is examined under polarized light microscopy to identify and characterize the crystals. The shape, size, and birefringence of the crystals are key factors in making a diagnosis.
6. Clinical Relevance: Analyzing synovial fluid for crystals is essential for diagnosing and managing inflammatory joint conditions. Accurate identification of crystal types can guide appropriate treatment strategies and provide insights into the underlying metabolic conditions.
