This study aimed to evaluate the diagnostic value of synovial fluid ADA (SF-ADA) in TB arthritis. Of 43 patients enrolled, nine had confirmed TB arthritis. Fourteen had non-TB septic arthritis, and 20 patients had non-infectious etiologies. The SF-ADA levels were significantly elevated in patients with TB arthritis compared to those with non-infectious origin (P <0.05). All SF-ADA levels were ?76 U/L in TB arthritis and ? 60 U/L in non-infectious synovial fluid. The ADA was not different between TB arthritis and non-TB septic arthritis (P = 0.87). The possibility of identifying synovial fluid with an ADA under 60-76 U/L of tuberculous etiology may be very low. In addition, an SF-ADA ?76 U/L with negative ordinary bacterial culture results is highly suspicious for TB arthritis.</p> <p><strong>Continuous...</strong></p>}, number={4}, journal={Journal of the Pakistan Medical Association}, year={2021}, month={Nov.}, pages={1246–1248} }
