August 2021—Verichem Laboratories offers liquid-stable, protein-based clinical reference materials for total and direct bilirubin assays. The Bilirubin Standard Kit, Tru-Zero Bilirubin Standard, and extended-range Level F Bilirubin Standard are intended for CLIA calibration verification with wet chemistry testing systems. Verichem’s BR2 Bilirubin Calibrator is available for use exclusively with the BR2 Bilirubin Stat Analyzer from Advanced Instruments.
The clinical reference materials incorporate a proprietary stabilization process, the company says, and do not have azides, glycols, or surfactants. Each vial contains 5 mL of material; refrigerated open-vial stability is five days and the shelf life is 18 months when stored at 2°–8°C. Concentration levels are verified using pure crystalline bilirubin and analyzed by the Doumas reference method.
Also offered by the company is the Matrix Plus Cholesterol Reference Kit for the calibration and calibration verification of wet cholesterol and uric acid assays on clinical testing systems. The product maintains a constant protein content and neutral pH across concentration levels. The cholesterol concentrations range from 40 to 750 mg/dL and the uric acid range is from 2 to 30 mg/dL.
