Rheumatology…Joint fluid analysis (Pathology)

Rheumatology…Joint fluid analysis (Pathology)

Check out my brand new “Electrolytes” course at and use the PROMO code: ELECTROLYTES50 to get a 50% discount. Joint fluid aspiration (arthrocentesis) can help diagnose a variety of rheumatological diseases via synovial fluid analysis.
The doctor taps the joint and aspires the synovial fluid, then send it to the laboratory for examination.
The lab comments on the fluid’s color, aspect (clarity), consistency, viscosity, WBC count, RBC count, glucose,…etc.
The normal synovial fluid is colorless, clear, thin, stringy, possesses an intermediate viscosity, has a WBC count of fewer than 200 cells/mm3, free of RBCs, bacteria, fungi or viruses.
The glucose level in the synovial fluid should — normally– be slightly lower than that of the plasma.
In this video, we discuss the joint fluid analysis of osteoarthritis, rheumatoid arthritis, gout, sjögren syndrome, systemic lupus erythematosus, as well as septic arthritis.

A new rheumatology video will be uploaded every Saturday, so please subscribe.
