Description
Estimated cost for Synovial Fluid Analysis at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
Synovial fluid analysis is primarily used for: 1. Diagnosing the cause of joint pain, swelling, or inflammation, 2. Distinguishing between infectious and non-infectious causes of arthritis, 3. Identifying specific types of arthritis, such as gout or rheumatoid arthritis, 4. Assessing the effectiveness of treatment in patients with joint diseases, 5. Monitoring the progression of joint conditions over time.
Normal Range
The normal range for synovial fluid analysis includes: White Blood Cell (WBC) count <200 cells/µL, Red Blood Cell (RBC) count <2000 cells/µL, glucose level within 80-120 mg/dL, and protein concentration between 1.5 to 2.5 g/dL. The appearance should be clear and colorless or pale yellow.
Low Values - Possible Causes
Low WBC count in synovial fluid can be caused by: 1. Normal joint condition, 2. Early stage of an inflammatory process, 3. Non-inflammatory joint conditions such as osteoarthritis, 4. Insufficient sample volume, 5. Technical errors during the test.
High Values - Possible Causes
High WBC count in synovial fluid may indicate: 1. Infection (bacterial, viral, or fungal), 2. Inflammatory arthritis (e.g., rheumatoid arthritis), 3. Gout or pseudogout, 4. Trauma or injury to the joint, 5. Hemarthrosis (bleeding into the joint).
