The synovial fluid guidelines provided have not been validated, but the following recommendations can be considered:
**Synovial Fluid Guidelines**
1. Run a standard curve with an additional standard point compared to the standard protocol in a buffer matrix.
2. Add 100 µl buffer + 25 µl standard/sample.
3. Agitate for 10 minutes at room temperature (RT).
4. Add 25 µl beads.
5. Incubate with agitation overnight at 4°C.
6. Follow the protocol for Det Ab and SA-PE steps.
7. Resuspend the beads in 200 µl of 1X Wash Buffer before loading onto the LMX.
8. The volume read is 100 µl on Luminex.
