TNHS test repeatability and intralaboratory precision.
| High-sensitivity troponin (pg/ml; ng/l) |
Assay output requirements | |
|---|---|---|
| Repeatability (within the same series) (CV (%)) | Intralaboratory precision (total) (CV (%)) | |
| 9-20 | ≤10% | ≤12% |
| >20 | ≤10% | ≤10% |
Precision was assessed in accordance with the EP05-A3 protocol of the Clinical and Laboratory Standards Institute (CLSI): “Evaluation of Precision of Quantitative Measurement Procedures; Approved Guidelines—Third Edition” (CLSI Document EP05-A3).
