Verichem offers clinical reference materials for the calibration verification testing of lactate assays

Sept. 20, 2022
New clinical reference materials for testing lactate assays.

Verichem laboratories announced 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 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 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.
