The Waters MassTrak™ Steroid Serum RUO Sets support precise steroid measurement in clinical research, helping laboratories optimize method performance and achieve reliable, consistent results.

Designed to streamline laboratory workflows, these comprehensive sets include calibrators and quality controls (QCs) traceable to National Institute of Standards and Technology (NIST) certified reference material (CRMs), along with internal standards and an optimization mix. By eliminating the need for in-house preparation, the sets help laboratories save valuable time and resources while supporting consistent analytical performance.

Overview

Comprehensive, Ready-to-Use Standards: MassTrak Steroid Serum RUO Sets provide essential standards for laboratory-developed test (LDT) development, including calibrators, QCs, internal standards, and an optimization mix, helping streamline workflows and reduce preparation time.
Traceability and Quality: Calibrators traceable to NIST CRMs and reference measurement procedures, along with quality controls, support laboratories in meeting applicable ISO 15189 requirements.
Flexible Method Development: Broad, customer-informed analyte concentration ranges, combined with a flexible design featuring 7+1 calibrator levels and four QC levels, enable laboratories to tailor methods to their specific LDT requirements.
Consistent Analytical Performance: High lot-to-lot manufacturing consistency and standardized value assignment support reliable LC-MS/MS method performance and comparability across laboratories.
Extended Stability and Cost Efficiency: Extended shelf life and in-use stability support prolonged product use, helping laboratories minimize reagent costs per batch when following RUO steroid analysis methods described in the Waters Application Note library.
