Furthermore, EtG (Helander and Dahl, 2005; Hoiseth etal., 2007b), but not EtS (Helander and Dahl, 2005), is sensitive to bacterial hydrolysis if infected samples are stored improperly, implying a risk also for obtaining false-negative results.

FOIA Diabetics are also at risk of a false-positive result on an EtG alcohol test. Our EtG test is performed by the LCMSMS method and simultaneously detects both EtG and EtS. Therefore, it is an efficient test to detect alcohol use. The ability to detect EtS using LC/MS/MS separates us from other laboratories in the United States. The EtG test is done by using a urine sample and is a quick way to detect current alcohol levels and check for recent alcohol consumption. The detection and quantification limits of this method are 0.05 and 0.1 mg/L, respectively, but for clinical purposes, a cut-off limit of 0.5 mg/L EtG (2.2 mol/L) is routinely applied (Bttcher etal., 2008), while EtS is used as a confirmatory test (limit of quantification 0.1 mg/L). All of those products have the potential to affect the results of an EtG test. We have the capability of measuring consumption up to 80 hours afterward. Three different test levels are commonly available: Our Ethyl Glucuronide test is a confirmation test! Today, a lower dilution threshold for urine creatinine (usually 20 mg/dL) is often applied in urine drug testing (Fraser and Zamecnik, 2003), but it should be pointed out that this cut-off still allows for a significant intentional urine dilution to take place. Also consumption of very small ethanol doses (10 g) is detectable for many hours afterwards (Stephanson etal., 2002; Helander and Beck, 2005; Wurst etal., 2006) and even unintentional intake from the use of ethanol-based mouthwash (Costantino etal., 2006) and hand sanitizers (Rohrig etal., 2006) could yield a positive urinary EtG and EtS, if applying a very low analytical cut-off limit.
