Verichem Laboratories offers multi-level enzyme calibration verification materials for liver function testing as part of its liquid stable and ready-to-use Enzyme ER Verifier Kit. The kit contains the enzymes Alanine Aminotransferase (ALT/SGPT), Alkaline Phosphatase (AP/ALP), Aspartate Aminotransferase (AST/SGOT), Gamma-Glutamyl Transferase (GGT/GGTP), and Lactate Dehydrogenase (LD/LDH); which are key diagnostic enzyme tests for the diagnosis, treatment, and monitoring of patients with liver disease. The availability of these essential products is certain to address the needs of many medical laboratory professionals – including those involved with routine clinical testing, medical diagnostic R&D applications, and in the manufacturing of in-vitro diagnostic (IVD) products.

Verichem’s Enzyme ER Verifier Kit for liver function testing represents the cutting-edge in enzyme calibration verification materials, as its proprietary, liquid formulation is specifically designed to include at least one concentration for each enzyme within the normal range. These verifiers are intended to be treated as patient specimens and feature universal instrument compatibility, making them available for use on a wide assortment of wet chemistry systems from Abbott, Beckman Coulter, Roche and Siemens. Manufactured from purified source components, the liquid stable, biosynthetic format eliminates matrix variations and reconstitution errors commonly experienced with lyophilized or serum-based products. Plus, the product features an outstanding shelf-life and open-vial stability claim of eighteen (18) months.

The material’s protein balance, pH, and ion content are constant across concentration levels for optimum linearity. Verichem’s Enzyme ER Verifier Kit is conveniently packaged for multi-use and contains an ample, five milliliters (5mL) of material for each of the six (6) levels, with  each  level  filled into  easy-to-use polyethylene dropper vials.  As an added bonus, the kit materials also contain multi-level assigned activities for the additional enzyme components Amylase (AMY), Cholinesterase (CHE), Creatine Phosphokinase (CK/CPK), and Lipase (LIP).

For close to 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  ̶including FREE online  data  reduction and comprehensive test reports for full CLIA compliance. .
