Increasing the quality, results, and throughput of the assays in your clinical diagnostics laboratory is a priority but sourcing high quality material that is cost effective can be a challenge for your operations and bottom line.
With the MassTrak Immunosuppressant Calibrator, Quality Control, and Internal Standard Sets, you can achieve the LC-MS/MS quality, results, and throughput you need in a cost-effective solution. With these sets your lab can ensure your analysis is delivering accurate quantification of drug levels and can detect systematic analytical deviation from reagents or analytical instrument variations. With MassTrak Immunosuppressant Standard Sets, you can ensure optimal method performance to account for sample matrix effects for the analysis of cyclosporine, sirolimus, tacrolimus, and everolimus in human whole blood samples – so you can be confident in your lab’s immunosuppressant analysis.
Metrological traceability of the Waters MassTrak immunosuppressant calibrator and quality control sets
In this application note, Waters discusses the requirement for compliance with local regulatory guidelines and international standards in the development and validation of laboratory developed tests (LDTs) within clinical laboratories. The implementation of ISO 15189:2012 in some geographies necessitates the use of metrologically traceable calibration materials. Metrological traceability and accuracy of results are important aspects of the design, development, and manufacture of the Waters MassTrak™ Immunosuppressant Calibrator and Quality Control Sets (IVD), which help laboratories harmonize their results when using validated LC-MS/MS methods. This application note provides an overview of the Waters MassTrak Immunosuppressant Calibrator and Quality Control Sets and their accuracy, as well as comparisons across lot-to-lot testing.
