Verichem Laboratories launched a multi-level set of liquid stable and ready-to-use clinical reference materials for the calibration and calibration verification of Ammonia assays.

The materials feature universal compatibility and can be used with a broad offering of clinical testing systems, including those from Abbott Diagnostics, Beckman Coulter, Roche Diagnostics, and Siemens Healthineers, and are explicitly designed for assays employing either enzymatic or colorimetric test methodologies.

The five-level standard kit, along with an optional and stand-alone sixth level, features an array of Ammonia concentrations ranging from 10 mcg/dL to 2000 mcg/dL, which is aimed to meet the needs of a variety of laboratory professionals, including those involved in routine clinical testing, research applications, or within in-vitro diagnostic (IVD) manufacturing facilities.

Verichem’s clinical reference materials for Ammonia incorporates a liquid stable format which is free of glycols, surfactants, azides, and other interfering substances, and prepared from reagent grade source materials, with Ammonia concentrations verified using American Chemical Society (ACS) reagent grade independent primary standards. Not only are the materials  uniquely designed to support this critical trace analyte, but they also demonstrate exceptional lot-to-lot duplication and product performance claims; while the set point design with equidistant target concentrations, addresses the current CLIA requirements for calibration verification materials used for the determination of a clinical system’s accuracy, sensitivity, linearity, and reportable range.

All of the available reference materials have a 24 month stability, when stored at 2°C to 8°C, and are packaged within convenient and easy-to-use translucent, polyethylene dropper vials, containing an ample fifteen milliliter (15.0 mL) fill volume thereby making the products ideal for numerous calibration verification events or test system troubleshooting.

The materials also offer Iron concentrations as well, which have been verified using available Standard Reference Materials (SRM) from the National Institute of Standards and Technology (NIST) with Iron concentration levels ranging from 10 mcg/dL to 1000 mcg/dL; with a Certificate of Analysis (COA) indicating traceability and actual lot  data provided with each kit.
