Which test is used to confirm that synovial fluid is indeed synovial fluid by observing hyaluronic acid clot formation?

The key idea is that synovial fluid contains mucin (hyaluronic acid) that gives it a distinctive gel-like consistency. In the mucin clot test, a sample is treated with acetic acid, which allows the mucin to form a visible clot or gel. If a firm mucin clot forms, it confirms the presence of synovial fluid because this mucin- rich clot is characteristic of synovial fluid. The other options don’t serve this purpose: Gram stain and culture test for bacteria, not for identifying synovial fluid, and the string test is just a quick viscosity check rather than a definitive confirmation of mucin content.
