Reply to 'kL-6 is not ineffective biomarker of indium lung' by Nakano et al. (Letter to the Editor)

摘要

In our report, we mentioned "The Japan Society for Occupational Health proposed 3 lg/1 of indium in serum as an occupational exposure limit is conducted based on biological monitoring to prevent significant increase in KL-6 (Omae et al. 2011). However, in the present study, the geometric mean of S-In level was lower than 0.73mug/1 (maximum: 0-18.42 mug/1), which was also lower than 3 jag/1. Therefore, KL-6 may be not an appropriate indicator to evaluating the health illness for ITO workers".
