Do we now know what inappropriate laboratory utilization is? An expanded systematic review of laboratory clinical audits.

abstract：Objectives:Approximately 15% of breast cancers show equivocal human epidermal growth factor receptor 2 (HER2) results on HER2 immunohistochemistry (IHC) and are reflexed for fluorescence in situ hybridization (FISH). However, some cases remain equivocal. In this study, we evaluated these double-equivocal cases by using...
