| UKAS Accredited Proficiency Testing Provider No | 8560 |
| Objective of Scheme | Provides EQA for point of care methods for cardiac troponin I, cardiac troponin T, CKMB, myoglobin and NT-proBNP. Combined samples are issued for troponin, CKMB and myoglobin to enable assessment of multi-analyte panels. Separate samples are issued for NT-proBNP to enable coverage of the analytical range. This Scheme does not cover very low levels of troponin, detectable by high sensitivity assays; a separate scheme is available for these methods |
