VERICHEM LABORATORIES now offers the multi-level/analyte and ready-to-use ENZYME ER™ Calibration Verifier Kit, which is certain to address the needs of a wide variety of medical laboratory professionals – including those involved with routine clinical testing, research applications, and in the development and manufacturing of in-vitro diagnostic (IVD) products. The materials are expressly designed for the calibration verification of enzyme assays on “wet” chemistry testing system and are contain nine (9) separate clinical enzyme components covering a total of fifty-four (54) individual activity levels. The enzyme components included within the materials include Amylase, ALT, ALP, AST, Cholinesterase, CK, GGT, LD, and Lipase.

Verichem’s ENZYME ER™ Verifiers represent the cutting-edge in enzyme calibration verification materials, as its proprietary formulation is specifically designed to include at least one set point for each enzyme within the normal range. These reference materials are intended to be treated as patient specimens and feature universal instrument compatibility, making them available for use on a wide assortment of clinical instrument systems, as well as offering an outstanding shelf-life and open-vial stability claim of a full  eighteen (18) months. Plus, the use of purified source components used in the manufacturing process, along with the liquid stable format, eliminates matrix variations and reconstitution errors commonly experienced with lyophilized or serum-based products.

In addition, the material’s protein balance, pH, and ion content are constant across concentration levels for optimum linearity. The linear relation for the materials is included in the product insert so that the kit can be used for reportable range verification of any automated “wet” chemistry method. Plus, for added  convenience, a separate value assignment sheet is included with targets for popular Abbott, Beckman Coulter, and Roche Diagnostics clinical chemistry systems. Verichem’s ENZYME ER™ Verifiers are conveniently packaged for multi-use and contain an ample five milliliters (5.0 mL) of material for each of the six (6) levels contained within each kit, with each level filled into easy-to-use polyethylene dropper vials.

For almost four decades, VERICHEM LABORATORIES has served the clinical laboratory testing and in-vitro diagnostic R&D and Manufacturing markets with a comprehensive line of clinical reference materials, calibration verification products, chemistry standards, linearity confirmation materials, and support services  ΜΆ  including FREE online  data  reduction and comprehensive test reports for full CLIA compliance.
