VERICHEM LABORATORIES is pleased to announce the availability of a liquid stable and ready-to-use set of clinical reference materials for use with the clinical testing of lactate.  The six level, protein based kit is expressly designed for the calibration or calibration verification of the assay on automated clinical systems.  Lactate tests are typically ordered when a patient displays signs and symptoms related to sepsis, shock, heart attack, severe congestive heart failure, kidney failure, or uncontrolled diabetes.  The materials feature universal instrument compatibility and can be used with most wet chemistry analyzers, including those from Abbott Diagnostics, Beckman Coulter, Roche Diagnostics and Siemens Healthcare.  This unique clinical reference material is treated exactly as patient specimens and sure to meet the needs of a variety of laboratory professionals involved in routine clinical testing, research applications, or within in-vitro diagnostic (IVD) manufacturing facilities.   

The multi-level product comprises a definitive set of the analyte by containing concentration levels of lactate ranging from 0.4 to 17.8 mmol/L (3.2 mg/dL to 160.0 mg/dL).  The liquid stable format is free of glycols, surfactants, azides and other interfering substances. The serum-free biosynthetic matrix is uniquely designed to support this critical analyte, while offering exceptional lot-to-lot reproducibility and product performance claims.  The gravimetric concentration design addresses the current CLIA requirements for calibration verification materials with known values and the concentration levels are verified using available USP Reference Standards.

The standards are filled in convenient and easy-to-use translucent polyethylene dropper vials containing five milliliters (5 mL) of material. The standards are prepared from highly purified source materials and feature an impressive shelf-life claim eighteen (18) months from date of manufacture.  In addition, a Certificate of Analysis (COA) indicating traceability and actual lot data is provided with each kit.  This unprecedented product also provides Acetaminophen, Ethanol, and Salicylate concentrations verified using available Standard Reference Materials from the National Institute of Standards and Technology (NIST) or, USP Reference Standards.

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 compliance.
