β2轉鐵蛋白可能非中耳液體內腦脊髓液特異性指標

// Beta-2 Transferrin May Not Be Specific for Presence of Cerebrospinal Fluid in Middle Ear Fluid

本研究透過定量ELISA分析71例中耳液樣本｜結果顯示77.5%樣本含有β-2轉鐵蛋白（B2T），其中年輕患者及黏液性積液或復發性急性中耳炎患者比例較高｜研究提醒臨床上B2T在中耳液中非腦脊髓液漏特異性，特別是兒童病例需謹慎解讀結果。

// This study aimed to measure beta-2 transferrin (B2T) presence in middle ear fluid of patients receiving pressure equalization tubes for recurrent acute or chronic otitis media. Using quantitative ELISA on 71 ear samples, 77.5% were B2T-positive, especially in younger patients and those with mucoid effusions or RAOM. The findings indicate B2T is not specific for cerebrospinal fluid leaks in the middle ear, cautioning clinicians in interpreting B2T results in these cases, particularly in children.
