| Comments of Review Teams | The laboratory participated RELA ring trials each year from 2013. The results of 2016 RELA were just at the edge of the limits of equivalence and the results of 2017 RELA (which were not published) were outside. The additional information SCCL provided indicates the corrective action is effective. The laboratory got good results both in 2018 RELA and 2019 External Quality Assessment for Reference Laboratories( in the area of China, provider is NCCL) |
