synovialFluidAnalysis
Reviewed
A group of tests that checks for changes in synovial fluid to help diagnose the cause of joint pain, swelling, and inflammation. The analysis usually includes checking the fluid's appearance, chemical tests, and microscopic analysis for crystals, bacteria, and other substances.
Preparation and collection
You may need to fast (not eat or drink) for several hours before the test. Your provider will let you know if you need to fast and if there are any special instructions. Tell your provider if you are taking any blood thinner medicines.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- The source does not provide specific reference intervals, units, or performing laboratory details.
- Interpretation requires correlation with symptoms, medical history, and other tests.
- Serious complications from the procedure are uncommon but possible.
What to do next
If you have questions about your results, talk to your provider.
