What’s unique on PEth (alcohol biomarker) in blood based testing

Looking for a reliable and accurate alcohol biomarker test?

Look no further than our Adult PEth Testing!

At Carolina Diagnostic Labs, our Mass Spec based test measures Phosphatidylethanol (PEth), a mid-to-long-term alcohol biomarker created in red blood cells, which may be detected in blood for up to approximately 2-4 weeks. Our testing is available in dried blood spots so no more (venipuncture) for your convenience. While there may be isolated circumstances where PEth may be detected at 6 weeks or more, our test is a reliable and accurate way to measure alcohol consumption. Learn more about PEth by reading the relevant foundational research.
