What Does Your Joint Fluid Say About Your Health?
Published: Mar 25, 2024
Understanding what synovial fluid analysis reveals can help pinpoint the cause of joint pain and swelling. Dive into the basics and discover how this simple test can lead to a more accurate diagnosis.
The Basics of Synovial Fluid
Synovial fluid is a lubricant found in your joints, allowing smooth movement and reducing friction. When something goes awry, this fluid can become inflamed or infected, leading to arthritis or other joint issues. By analyzing this fluid, doctors can determine whether your joint problems stem from infections, crystals, or other causes.
Collecting and Analyzing Synovial Fluid
Doctors perform a procedure called arthrocentesis to collect synovial fluid from your joint. This involves using a needle to extract fluid under sterile conditions. Once collected, the fluid is analyzed for clarity, color, and viscosity, alongside tests for white blood cells, bacteria, and crystals, which provide crucial clues about your joint health.
Interpreting the Results
The analysis results can categorize the fluid as noninflammatory, inflammatory, septic, or hemorrhagic. Noninflammatory fluid suggests conditions like osteoarthritis, while inflammatory fluid indicates issues like gout or rheumatoid arthritis. Septic fluid shows infection, and hemorrhagic fluid may point to bleeding disorders.
