A line of liquid stable, protein based, bilirubin reference materials are now available from Verichem Laboratories. The Bilirubin Standard Kit, and the optional Bilirubin Standard-Level F, are specifically designed and intended for CLIA calibration verification of total and direct bilirubin assays with any wet chemistry, clinical testing systems. The company also offers the TRU-ZERO™ Bilirubin Standard as an optional zero concentration (0.0 mg/dL) level for both analytes.
Certain to address the needs of a wide variety of medical laboratory professionals, Verichem LABORATORIES’ ready-to use bilirubinstandards are treated as patient specimens, with no preparation or diluents required. All have had their assigned concentration levels verified with the Doumas Reference Method, and the included Certificate of Analysis provides verification data using pure crystalline bilirubin reference material. The standard’s unique protein-based formulation, along with a set point design using CLSI EP06-A linearity protocol, are critical for the determination of the testing method’s accuracy, sensitivity, linearity and reportable range.
All of the standard materials are conveniently packaged in amber serum vials with rubber-lined closures containing five milliliters (5.0mL) of standard at each level. The Bilirubin Standard Kit contains five (5) concentration levels, while the extended range Level F also contains two (2) vials of with a 30 mg/dL concentration level. Plus, all of these unique bilirubin standards incorporate a proprietary stabilization process which negates the need for azides, glycols or surfactants and feature an exceptional refrigerated open-vial product stability claim of five (5) days, with a shelf-life claim of fourteen (14) months, when stored at 2 to 8 °C.
