Validation and implementation of the fifth-generation high sensitivity Troponin T (hs-TnT) assay at a large teaching county hospital. A laboratory-driven multi-speciality effort

We describe the validation and implementation of the new 5th generation high sensitivity Troponin T assay (Roche Diagnostics®). In addition to the assay improved sensitivity, the numerical values, reporting units, reference intervals, and critical limits are markedly different. We describe the use of clinical correlation as the basis for implementation and validation of the fifth-generation hs-TnT assay at a large teaching county hospital.
