AthenaES™ Reference Standards
AthenaES™ offers the G-Mark™ Product Line, consisting of calibration standards and tools for alcohol use detection. Ingested alcohol is converted to ethyl glucuronide (EtG, a glucose derivative), ethyl sulfate (EtS) and other metabolites in the body. EtG and EtS can be detected in blood and urine up to 5 days after alcohol usage. Current methods require the use of calibration standards for accuracy.
