In this issue, Jatlow and colleagues have provided the field with the report of awell done and timely scientific evaluation of one of the newer alcohol consumption biomarkers,urinary ethylglucuronide (EtG), and a related metabolite, ethylsulfate (EtS). These naturallyoccurring chemical conjugates between ethanol and glucuronide (EtG) or sulfate (EtS), whileelegant in their simplicity, have caused a certain amount of discussion and controversy notonly in the literature, but also in clinical practice ( Centerfor Substance Abuse Treatment, 2012 ; Litten et al.,2010 ). EtG and EtS have been around for some time ( Wurst et al., 2003 ), but highly structured investigations into their interpretationand utility have been few ( Wurst et al., 2004 , Hoiseth et. al., 2012 ). The concerns which have haunted bothinvestigators and clinicians alike, and which have spilled over into forensic circles, involvecut-off le Continue reading >>

I'm Diabetic. I Had A Urine Drug Test That Came Up Positive For Alcohol But Don't Drink. How Is This Possible?

Answered Jun 9, 2018 Author has 4.7k answers and 2.3m answer views Ethanol is extremely common in our everyday lives and it can be found in over four hundred household products including cleaners, beauty products, foods, and medications. There is evidence that incidental EtG exposure can occur even in the absence of contact with the individuals skin. Simply inhaling the vapors created by antibacterial hand sanitizers can be enough to elevate EtG levels and, in fact, this increase can be very high. Research has proven that such incidental exposure to alcohol can result in a false positive on an EtG test. For this reason, the Substance Abuse and Mental Health Services Administration (SAMHSA) has issued an advisory against using EtG tests in probative settings . Answered Jun 9, 2018 Author has 8.1k answers and 96.2m answer views Most mouthwashes contain high levels of alcohol. I use Listerine and if you use that and then blow into a breathalyzer you will likely blow a high enough level of mouth alcohol to be a concern. The mouth alcohol dissipates after 20 minutes, so it is Ok if you get pull over a half hour later. When some people gargle with mouthwash, they can swallow some of it and it will end up in the blood stream in enough quantity to show up on a test.

Many of these products contain minute traces of alcohol but could prove problematic for people who are in programs where there is zero tolerance for alcohol. Scientific studies have found that EtG may show up in urine samples from people who regularly use things like mouthwash and hand sanitizer, however, these levels will almost always be below the commonly accepted cut off limit of 500 nanograms per milliliter (ng/ml). False negative and false positive results have also been noted in test results due to bacterial contamination from the presence of E. coli bacteria. Avoiding these false negatives is why it is important to test for EtS at the same time as EtG. The inclusion of laboratory EtS testing in conjunction with EtG testing has proven effective in avoiding most false positives and false negatives and provides analytical results that are acceptable in court. Due to the concerns about incidental exposure, positive results need to be backed up with a second test that verifies those results. This is especially true in any case that involves a court and a judge overseeing the matter. There are already plans in place to find the right level at which it is appropriate to consider a true positive on the test. Once this aspect of the EtG test has been established and it gains FDA approval, EtG stands to be a much improved and more consistent way of testing for employee alcohol use . With its help, many businesses will be able to improve the way they run their business. EtG home testing will also prevent early alcohol abuse in young people. When interpreting results foralcohol EtG tests like the 13 PanelT-Cup Urine Drug Test Cup With EtG , its important to consider the cutoff levels, normalization of results and the use of both EtG and EtS for confirmation results.

Alcohol is rapidly eliminated from the body at a rate of approximately one drink per hour. Whether looking for alcohol in breath, blood, saliva or urine, using the standard technology, the rapid elimination limits the detection of alcohol to a matter of hours. For example an individual who was under the influence of alcohol using standard technologies (breath, blood or saliva > 0.08%) at 10 PM would likely test negative the next morning at 9 AM due to the rapid elimination of alcohol from the body. After years of research, Ethyl Glucuronide (EtG) was found to be a direct metabolite of the alcohol (ethanol). EtG has emerged as the marker of choice for alcohol and due to the advances in technologies is now routinely available. Its presence in urine may be used to detect recent alcohol consumption, even after ethanol is no longer measurable using the older methods. The presence of EtG in urine is a definitive indicator that alcohol was ingested. Other types of alcohol, such a stearyl, acetyl and dodecanol, metabolizes differently and will not cause a positive result on an EtG test. The EtG test has become known as the 80 hour test for detecting any amount of consumed ethyl alcohol. This is not totally true. It is true that EtG can be detected in chronic drinkers for 80 hours or even up to 5 days. During this period of chronic use, the EtG level can exceed 100,000 ng/mL. Two primary factors to determine the window of detection is based on volume of alcohol consumed and the time between each drink. A person that consumes 3 drinks can only have a detectable level of EtG for approximately 20 to 24 hours and peaks at approximately 9 hours with an EtG level around 15,000 ng/mL. Therefore, the presence of EtG in urine indicates that ethanol was ingested. EtG is a more accurate i Continue reading >>

Is it possible for a false positive or alcohol in a urine test if youre diabetic?Im in a suboxone clinic and I get tested every two weeks.I was positive two consecutive times in July when I had my toe amputated and then it was fine now I tested positive again in November two consecutive times again.Back in July I had a UTI and believe I might again.Help Im accused of drinking and theyre going to throw me out of the programI don't drink and don't use any OTC products with alcohol It is possible for the urine test for alcohol to give a false positive. If they are testing for EtG, the use of other household products such as hand sanitizer, or mouthwash that contain alcohol can cause a positive result. In these cases the alcohol is absorbed through the skin or oral mucosa. Additionally, diabetics can get a false positive result if the urine sugar level is elevated and yeast is present in the urine. The yeast can ferment the sugar into alcohol if the test is allowed to sit for a while before it is tested. Continue reading >>

Urine Testing For Alcohol

Urine Testing For Alcohol

Alcohol may be tested for using urine , there are several options. It is important to clearly order the appropriate alcohol test for your employees, offendersor patients. Ethyl Alcohol Test also known as a UA or urine alcohol test. The detection time is 1 12 hours. There are several concerns with using urine alcohol for workplace testing and in evaluating whether a person is impaired by alcohol or has consumed beverage alcohol, including the following: A positive urine alcohol test is not indicative of alcohol impairment nor does it definitively indicate beverage alcohol consumption. If an individual is a diabetic and has a yeast or bacterial infection, fermentation can take place. Fermentation is the process of the yeast/bacteria consuming glucose resulting in the production of alcohol. It is possible that the glucose may no longer be detectable as the yeast/bacteria may have already consumed all the glucose. Individuals spilling sugar into the urine for whatever reason can also cause fermentation if yeast or bacteria are present and if the transit time is prolonged. The longer the specimen is in transit the chances of fermentation occurring are greater. Urine testing for alcohol is not covered under current laboratory certification standards and testing protocols. It is currently the least effective method in determining the amount of alcohol in the body. The blood to urine ratio has a wide range and can be affected by many factors, therefore, it is difficult to equate a urine test result for alcohol to a particular blood or breath alcohol level. USA Mobile Drug Testing recommends breath alcohol testing for workplace clients who wish to determine impairment or prohibited use of alcohol. This is also the DOT requirement. In Florida, under the Florida Drug Free Workpla Continue reading >>

Hand Sanitizer, Hairspray...anything that has alcohol. But you can also show a false positive if you have a UTI. Also you can have a false positive if you are a diabetic. I am not a nurse, but I do know something about etg testing. Thought I would share with you all. Etg tests are sensitive to alcohol metabolites as you have mentioned. It would be interesting to know how many ng's you all tested for. Anything under 500 ng's could/should be considered incidental exposure. Anything OVER 500 is definite alcohol consumption. That's not to say that anything under 500 is not alcohol consumption, just that it is too low to be positive that alcohol was consumed. Low levels could also indicate incidental abuse (ex: drinking high doses of cough syrup, vanilla extract, mouthwash, etc). After reading your post I guess I am wondering what makes you such an expert on ETG testing? I have tested positive 4 times in the past two years and have not had a drop of alcohol to drink. I am however, pre-diabetic and have frequent urinary tract infections, but the courts choose not to look at these facts. I am now facing time in prison because of these ETG tests and the fact that Dr. Skipper is claiming that these tests are highly innaccurate, so for you to tell me that anything above 500 is definite alcohol consumption only shows me that you don't know to much about ETG testing at all. This test is destroying lives, everyones body is different and ETG test Continue reading >>

Etg/ets Not Proof Of Drinking - Ethylglucuronide (etg) And Ethylsulfate (ets)

Etg/ets Not Proof Of Drinking - Ethylglucuronide (etg) And Ethylsulfate (ets)

Ethylglucuronide (EtG) and Ethylsulfate (EtS) A Positive EtG and/or EtS Alone Does Not Confirm Drinking There is currently no known cutoff for a positive EtG or EtS that confirms drinking. Before enumerating the reasons its important to know, however, that statistically most positive EtG/EtS levels are due to drinking, probably 90% or more, however, there are a significant percentage of positives not due to drinking and therefore a positive EtG/EtS doesnt prove drinking. The higher the EtG/EtS level, especially if corrected for concentration, the more likely the positive was due to drinking. In other words, low level positives (under 2,500ng/ml) can occur more often from incidental exposure to alcohol but theres no proof that levels above this could not also be from incidental exposure or combinations of exposures. There are two issues: Does a positive EtG/EtS prove drinking and can setting a cutoff level distinguish between drinking and other causes of positives? First: Why a positive EtG/EtS does not prove drinking: Incidental sources of exposure to alcohol are numerous and can be found in mouthwash, over-the-counter medications (cough syrups, Nyquil, etc), communion wine, alcohol-free wine and beer, foods (foods cooked with wine or fermented items, beverages containing sugar that have been opened and may have fermented, etc), and vapor of alcohol (from hand gels, perfumes, bug spray, gasohol, etc) and others. All of these sources can cause a positive EtG and their effects are additive. Alcohol can be produced inside the body if someone consumes yeast (such as bakers yeast) and sugar (such as in drinks or foods). This small amount of alcohol is metabolized into EtG and EtS. Second: Why is there no cutoff that clearly distinguishes between a positive EtG/EtS from drin Continue reading >>

Etg Alcohol Testing 80 Hour Look Back

... EtG and EtS are direct metabolites of alcohol (ethanol). Their presence in urine is used to detect recent ethanol ingestioneven after ethanol is no longer measurable. Detectable up to 80 hours after ingestion, the presence of both EtG and EtS in urine is a reliable confirmation method and indicator of ethanol ingestion. EtG detects recent ingestion more accurately and for a longer period of time than standard alcohol tests. National Drug Screening offers state-of-the-art technology and skilled laboratory staffing to ensure accurate EtG/EtS analysis. EtG alcohol testing is offered in all areas of the United States at our drug testing centers. Immediate service for EtG alcohol testing is available from National Drug Screening centers in every city. If you need an EtG alcohol test today, call our toll free number for immediate service. EtG is only detected in urine when alcohol is consumed. This is important since it is possible to have alcohol in urine without drinking. Alcohol in urine without drinking is due to the production of ethanol in vitro. Ethanol in vitro is spontaneously produced in the bladder or the specimen container itself, due to fermentation of urine samples containing sugars (diabetes) and yeast or bacteria. Since the ethanol produced is not metabolized by the liver, EtG will not be produced and will therefore not be detected in a urine containing alcohol as a result of fermentation. Ethyl glucuronide (EtG) is a direct metabolite of alcohol (ethanol). Its presence in urine may be used to detect recent ethanol ingestion, even after ethanol is no longer measurable. In addition to EtG, scientific studies have identified ethyl sulfate (EtS) as a second specific metabolite or biomarker of ethanol. For this reason, we test and report EtS, in conjunction w Continue reading >>

Assessment Of Alcohol Exposure: Testing For Ethylglucuronide(etg), Ethylsulfate (ets)

Alcohol use disorder is a leading cause of preventable death with serious consequences in many domains. There is an increasing need to fine tune detection and diagnostic methods to enable health care workers prevent, diagnose and manage this disorder. The diagnosis of an alcohol problem could be quite a challenge as the disorder can present as other psychiatric syndromes . The diagnostic armamentarium includes good history and clinical examination, screening tools and biomarkers. Biomarkers are divided into direct and indirect physiologic biomarkers and two of these, namely EtG and EtS, are proving to be a great asset in guiding clinicians to determine alcohol consumption, retrospectively, over many days Alcohol use disorders , Biomarkers, EtG, EtS Alcohol use poses a serious health and socioeconomic problem worldwide, being a leading cause of preventable death. The western hemisphere observes the highest number of people with alcohol related disorders, alcohol consumption and the consequential hardships and harms. In the United States alcohol was responsible for 1 in 10 deaths among working-age adults 20-64 years of age from 2006-2010, (CDC, 2014). The economic cost, for example, was estimated to be 249 billion USD or $2.05 a drink in 2010 (Sacks, 2010). Hence, it is very important to understand the aetiology, diagnosis, course and management of these disorders. The initiation of alcohol use depends on bio-psycho- social factors, which are considered to contribute up to 60%, with the remaining variance taken by environmental factors. Alcohol use disorders (AUDs) also share, with other addictions, the consideration of a developmental perspective, i.e. epigenetics (stress & trauma), drug exposure (in utero and postnatal) early drug use, family of origin and the influenc Continue reading >>

Pam If they found alcohol in the urine sample they took from me, How did it get ther if I have not had a sip of alcohol in over 9 mo.? I already told tou that I have Diabetes 2 and had just gotten out of the hospital for high blood gloucose. Is there any chemical reactions that could make alcohol show up in my urine. I"m telling the honest to god answer I DID NOT CONSUME ANY ALCOHOL! Drug Testing Expert: Kxav , Board Certified Physicianreplied 6 years ago Sorry for the delay. If your question is can diabetes cause a false positive drug test for alcohol, the answer is likely no as diabetes can cause a false positive for Amphetamines, THC, cocaine, ecstasy, meth, and opiates. It should not cause one for alcohol. Hope this helps. Sorry, I don't accept your answer. AfterI contacted you I fiddled around on my computer. I reaserched Norchem Drug testing. They said "Yes it is possible for a drug test to be possitive for alcohol as a result of diabetes. If you want to why, Please get a hold of this company. I got them on ask.com on FAQ within this co.

How Long Does Alcohol Stay In Your Urine? Urine Alcohol Test

How Long Does Alcohol Stay In Your Urine? Urine Alcohol Test

Home / Alcohol / Urine Alcohol Concentration and Urine Alcohol Test Urine Alcohol Concentration and Urine Alcohol Test A tested person empties the bladder completely and then, after 20-60 minutes, provides at least 45 milliliters (about 1.5 fl. oz) of urine [4]. To stimulate urination, the person may drink up to 40 oz (about 1 liter) water before the test [4]. In legal procedures in the U.S. the urine alcohol concentration (UAC) is considered to be 1.3 times as high as blood alcohol concentration (BAC) ,but this is close to the truth only for a certain period of time during which the blood alcohol concentration is falling[1]. The actual UAC/BAC ratios may range from as low as 0.1/1 to as high as 21/1 [3]. For example, low UAC/BAC ratios can be observed within the first 2 hours after drinking when there may be not much alcohol in the urine yet, and high UAC/BAC ratios can be observed when most of alcohol already disappears from the blood. Drinking water after drinking alcohol and before the test does not significantly reduce urine alcohol concentration; it only lowers urine specific gravity[5]. Errors during collecting, storing or testing urine samples may cause false positive or negative results [6]. For example, in an improperly stored urine sample of individuals withuntreated diabetes type 1 andurinary tract infection, bacteria or fungi can convert glucose to ethanol [7]. Causes of FALSE NEGATIVE urine alcohol test When the test is performedwithin 2 hours after stopping drinking,that is when the urine alcohol concentration (UAC) may be still lower than blood alcohol concentration (BAC), using the official UAC : BAC ratio 1.3 : 1 could result in a false negative estimation of BAC [8]. When not supervised, a tested person couldadd water into the urine sampleand thus lo Continue reading >>

Alcohol (ethanol) is the most abused drug worldwide (Table 1). Alcohol abuse affects over 18.5 million adults in the U.S., costing society over $200 billion annually in lost productivity, health care expenditures, motor vehicle accidents, crime and other related costs 1 . Alcohol related diseases contribute to a high percentage of all hospital admissions (more than 20 per cent) and deaths approximate 100,000 annually. Estimates also suggest that among children under age 18, one in four is exposed to family alcohol problems. Due to the host of medical, social, economic and personal afflictions associated with habitual drinking, it is essential that effective strategies be developed to prevent, diagnose, and treat alcohol-induced diseases as well as offenses 2 . The development of effective diagnostic tests to detect high-risk drinking behavior and alcohol-induced tissue damage is therefore required for these strategies. 20% of ingested ethanol is absorbed in the stomach and another 80% in the intestine. This is distributed into the total body water representing 75% and 66% for men and women respectively. About 90% to 95% of ingested ethanol is oxidized in the liver by alcohol dehydrogenase, aldehyde dehydrogenase and microsomal ethanol-oxidizing enzymes before elimination in urine 3 , 4 . Some of these oxidation products are responsible for pathologic effects ( Figure 1 ) often observed in individuals exposed to alcohol. Of the remaining ethanol less than 5% is eliminated unchanged in urine, sweat and breath. In these matrices ethanol itself must be measured in a relatively short time (less than 12 hours) post consumption in order for it to be detected ( Figure 2 ). However, the non-oxidative products of liver ethanol metabolism ( Figure 1 ) can be detected several days Continue reading >>

Six Facts About Testing For Ethyl Glucuronide (etg)

Six Facts About Testing For Ethyl Glucuronide (etg)

23 0 Ethyl glucuronide is a direct, minor metabolite that can be used as a biomarker for ethanol exposure. Like any other toxin, ethanol is excreted from the body in a variety of ways. These include: 1) Direct excretion of ethanol (5–10%) in urine, sweat and breath; 2) Metabolic excretion by conversion to acetaldehyde/acetic acid (> 90%); 3) Metabolic excretion by conversion to ethyl glucuronide and ethyl sulfate (< 0.1%), both of which are readily eliminated through urination. While most of these excretory products are detectable in urine for very short periods of time (less than 24 hours), ethyl glucuronide (EtG) and ethyl sulfate (EtS) have longer half-lives and may be detectable in urine for up to 96 hours, depending on the dose taken prior to specimen collection. Incidental exposure to ethanol from non-beverage sources may result in a positive drug test for EtG. Many common products purchased at grocery stores or pharmacies contain ethanol, which can cause a positive result in a drug test for EtG. These products include over-the-counter, alcohol-based cold and flu medications (e.g., NyQuil), food products (e.g., sauerkraut, balsamic vinegar, vanilla extract) and personal products such as mouthwashes. Additionally, certain popular drinks sold in stores (e.g., kombucha) may contain significant amounts of alcohol. It is also important to know that supposed non-alcoholic beverages may contain up to 1% ethanol by volume. In-vitro creation of EtG can occur in certain rare situations. A diabetic with a specific urinary tract infection represents perhaps the most common example of in-vitro formation of ethyl glucuronide in the body. If the patient’s diabetes is uncontrolled, excess glucose in the blood is excreted into the urine and can be fermented into alcohol by mic Continue reading >>

You havesaid that you consumed absolutely no alcohol. Does that mean that youhad not consumed any alcohol for a long while (weeks or months?) orwithin the past day or two?There are instances where high levels of sugar or acetone in the urinecan result in false positives for alcohol content. If you suspect thiscould be the case, it might be wise to have a medical check-up to seeif you have any abnormalities in urine composition.There is reference to the fact that laboratory error can result infalse positives for alcohol due to contaminated equipment as well asthe introduction of air into the sample.
