Liquid stable, multi-level clinical reference materials for toxicology testing
Verichem Laboratories has announced the availability of ready-to-use, multi-level, clinical reference materials intended for use with Toxicology assays on a wide array of diagnostic testing systems.
The component materials and available concentration ranges include Acetaminophen: 6.0 to 300.0 mg/L; Lithium: 0.20 to 4.60 mmol/L and/or 0.50 to 5.50 mmol/L; and Salicylate: 2.0 to 100.0 mg/dL. Expressly designed for testing as patient specimens for the calibration verification of the intended components, all materials feature universal instrument compatibility, making them suitable for use on a wide array of wet chemistry analyzers. These unique formulations eliminate time-consuming reconstitution procedures with a liquid, non-interfering matrix.
CLIA compliant concentration designs, at or near decision cut off concentrations, are vital for the determination of test method accuracy, sensitivity, linearity, and reportable range, with all concentrations directly verified using Standard Reference Materials available from either NIST or USP.
Verichem’s clinical reference materials for toxicology assays are ergonomically packaged and contain ample volumes of materials at each of the six available concentration levels to accommodate multiple calibration events or any potential troubleshooting incidents. The standards are filled within convenient polyethylene, multi-use dropper vials and include a lot specific Certificate of Analysis indicating accuracy traceability and actual lot testing data.
