Ready-to-use, liquid stable Clinical Reference Materials for Microprotein testing are now available from VERICHEM LABORATORIES. These unique products are intended for the calibration and calibration verification of clinical systems testing for total protein and albumin in both urine and cerebral spinal fluid (CFS). The five (5) level set of materials provides ten (10) individual certified concentrations, in a liquid stable, azide-free format, where all concentrations are assigned by definitive procedures using human protein components of known purity. Accurate measurement of microprotein and microalbumin levels are extremely useful in the early detection of kidney damage, while testing CSF is useful in detecting central nervous system disorders such as multiple sclerosis, (MS), or meningitis. As such, the availability of these materials is certain to address the needs of a wide variety of laboratory professionals, including those involved with routine clinical testing, medical research applications, and in the development and manufacturing of in-vitro diagnostic (IVD) products. 

Suitable for use with both turbidimetric and colorimetric test methodologies, Verichem’s Clinical Reference Materials for Micoprotein incorporates human protein components for optimum reactivity.  Each of the certified gravimetric concentration levels of these materials employs a distinctive set point design with equidistant target concentrations to address the current CLIA requirements for clinical system accuracy, sensitivity, linearity, and reportable range. The materials are conveniently packaged as a kit, containing a five (5) level set, with fifteen milliliters (15.0 mL) of material at each level which is ample enough to cover multiple calibration verification events, any unexpected system trouble-shooting, or any additional testing procedures The materials are filled in easy-to-use, translucent polyethylene dropper vials and offer an outstanding shelf-life stability claim of twenty-four (24) months from date of manufacture when stored refrigerated at temperatures of 2° to 8°C.  Plus, a Certificate of Analysis is included with each kit indicating traceability to available NIST and/or ERM® Standard Reference Materials.    

VERICHEM LABORATORIES serves the clinical laboratory testing and in-vitro diagnostic (IVD) 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
