New Licensing Agreement with RedHot Diagnostics on PEth Certified Reference Materials

We would like to announce that we have reached a licensing agreement with Sweden-based RedHot Diagnostics to manufacture and sell solution-based Certified Reference Materials (CRMs) of PEth alcohol biomarkers.

PEth, or phosphatidylethanol, is a group of phospholipids formed only in the presence of ethanol from the action of phospholipase D. These direct alcohol biomarkers demonstrate high sensitivities appropriate for determining moderate to heavy alcohol consumption.1 The superior sensitivity and specificity of blood PEth over other alcohol biomarkers for determining alcohol consumption has resulted in its wide use and recommendation in the US and EU as a confirmatory test for recent drinking.2,3

Under terms of the agreement, we have the exclusive rights to manufacture, sell, and market CRMs of major PEth analogs in all our global markets. In the coming months, we will be introducing under our Cerilliant® brand solution-based CRMs of PEth analogs 16:0/18:1 and 16:0/18:2 as well as a stable-labeled internal standard of 16:0/18:1 for use in liquid chromatography/mass spectrometry blood alcohol testing applications.

These products will soon complement and extend our comprehensive offering of Cerilliant® blood alcohol/ethanol solution CRMs, including single-component ethanol standards, multi-component alcohol mixes, Ethyl glucuronide & Ethyl sulfate urinary metabolites and their stable-labeled internal standards. Our Cerilliant® Certified Spiking Solutions® are manufactured using validated processes that ensure the highest level of accuracy for critical quantitative mass spectrometry-based applications from TDM, diagnostic, endocrinology and pharmaceutical research, to toxicology, forensic testing and clinical chemistry
