Redwood Toxicology Laboratory Announces EtG Testing

SANTA ROSA, Calif., April 4, 2006 - Redwood Toxicology Laboratory (RTL) today announced it now offers urine ethyl glucuronide (EtG) testing. EtG is an alcohol metabolite that remains in the body and is detectable in urine for up to 80 hours after the elimination of alcohol. EtG is only evident when alcohol is consumed and is not produced as a result of fermentation.

EtG testing is ideal for zero tolerance and abstinence situations in the drug and alcohol treatment industry. Standard urine alcohol testing currently used by most treatment programs does not allow for the accuracy and extended detection window that EtG testing provides. By utilizing liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS), the most sophisticated equipment and technology available, RTL is able to provide accurate and reliable results.

Robert Mount, RTL's Chief Executive Officer stated, "Many of our customers require a more sensitive test for the detection of alcohol use. RTL responded to customer demand by developing an affordable and reliable EtG test. We will continue to develop toxicology technologies to provide our customers with the most comprehensive drug testing programs available."
