The liquid-stable and ready-to-use Matrix Plus Cholesterol Reference Kit, containing known concentrations of both cholesterol and uric acid, is now available from Verichem Laboratories, Providence, RI. The materials are expressly designed to support overall system QC and CLIA compliance and are intended for the calibration and/or calibration verification of both “wet” cholesterol and uric acid assays on clinical testing systems.
This kit is designed to address the needs of a wide variety of clinical laboratory professionals, including those performing clinical diagnostic and research testing, as well as those involved with the development and manufacturing of in vitro diagnostic products, as the product is a valuable tool in determining a clinical system’s bias to the true, or known, value. By maintaining a constant protein content and neutral pH across concentration levels, the unique formulation and set point design of these reference materials are crucial for the independent determination of test method accuracy, sensitivity, linearity, and reportable range.
The cholesterol concentrations range from 40 mg/dL to 750 mg/dL, while the uric acid range is 2.0 mg/dL to 30.0 mg/dL. The materials are intended to be treated as patient specimens and suitable for a wide variety of testing analyzers and assay methodologies. Verichem Laboratories’ Matrix Plus Cholesterol Reference Kit is packaged in ready-to-use, liquid stable format, incorporating a bovine sourced protein-based matrix containing both esterified and free cholesterol for true serum-like reactivity.
The unique formulation features minimal lot-to-lot variation and is free of glycols, surfactants, azide, and other interfering substances. Each active component is verified using available standard reference materials from the National Institute of Standards and Technology (NIST) and fully documented with a Certificate of Analysis (CoA). This kit, in conjunction with the optional sixth Level F, aims to offer laboratories a definitive set of reference materials comprised of six separate concentration levels, covering 12 individual concentration points, for cholesterol and uric acid testing.
In addition, Verichem Laboratories’ Matrix Plus Cholesterol Reference Kit offers exceptional optical clarity and is conveniently packaged for multi-use containing 15 mL of material for each of the six levels contained within each kit. Each of the levels is filled into easy-to-use, opaque polyethylene dropper vials and offer an outstanding shelf-life stability claim of 21 months from the date of manufacture.
Verichem Laboratories serves the clinical laboratory testing and in vitro diagnostic manufacturing markets with a comprehensive line of calibration, verification products, chemistry standards, reference materials, and support services, including free, instant online data reduction reports for CLIA compliance.
