Verichem Laboratories, Providence, RI, has released its liquid stable, ready-to-use Matrix Plus chemistry reference kit, intended for the calibration, or calibration verification, of wet chemistry assays on clinical testing systems.
With materials expressly designed to support overall system quality control and compliance with the Clinical Laboratory Improvement Amendments of 1988, the kit is designed to meet the needs of a wide variety of clinical laboratory professionals. By maintaining a constant protein content and neutral pH across concentration levels, the unique formulation and CLSI EP06-A set point design of the reference materials are crucial for the independent determination of test method accuracy, sensitivity, linearity, and reportable range.
The set of definitive method reference materials contains seven routine chemistry components, covering 42 individual concentrations. Analytes include blood urea nitrogen, calcium, creatinine, glucose, magnesium, phosphorus, and triglycerides. The materials are intended to be treated as patient specimens with wet clinical testing systems, and are suitable for a wide variety of testing methods, including visible spectrum, ultraviolet, kinetic, and/or endpoint.
The Matrix Plus chemistry reference kit is packaged in ready-to-use, liquid stable format, incorporating a buffered protein-based matrix for serum-like reactivity. The formulation features undetectable lot-to-lot variation and is free of azide, glycols, surfactants, and other interfering substances. Each active component is verified using available standard reference materials from the National Institute of Standards and Technology.
