November 2021—Verichem Laboratories offers ready-to-use, liquid-stable clinical reference materials for microprotein testing, suitable for use with turbidimetric and colorimetric test methods. The products are intended for the calibration and calibration verification of clinical systems testing for total protein and albumin in urine and cerebral spinal fluid. The kit contains a five-level set with 15 mL of material at each level and provides 10 individual certified concentrations in an azide-free format, incorporating human protein components for optimum reactivity.
Each of the certified gravimetric concentration levels employs a distinctive set point design with equidistant target concentrations to address CLIA requirements for system accuracy, sensitivity, linearity, and reportable range. The materials are filled in easy-to-use, translucent polyethylene dropper vials and offer a shelf life of 24 months when stored refrigerated at 2°–8°C.
