Alcohol Testing

Alcohol Testing is vital in the workplace.

Georgia Onsite Labs offers alcohol testingAlcohol is the single most used and abused drug in America. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), nearly 14 million Americans (1 in every 13 adults) abuse alcohol or are alcoholics.

Accidents and on-the-job injuries are far more prevalent among alcoholics and alcohol abusers. There are different types of alcohol tests available. Urine Testing and Blood Testing.

Georgia On-Site Lab Testing offers the EtG/EtS 80 Hour alcohol test.

EtG is a direct metabolite of alcohol (ethanol). Its presence in urine and may be used to detect recent ethanol ingestion, even after ethanol is no longer measurable.

The presence of EtG in urine is an indicator that ethanol was ingested and can be detected in urine for up to 80 hours after ingestion. EtG is only evident when ethanol is ingested and is not produced as a result of fermentation .

The detection of alcohol in the urine typically employs Ethyl glucuronide (EtG), a direct metabolite of ethanol alcohol. The presence of EtG in the urine is used to detect recent alcohol consumption, even after the ethanol alcohol is no longer detectable by other methods. As a consequence, the existence of EtG in the urine is an authoritative indicator that alcohol has been ingested.Traditional laboratory practices usually measure the amount of alcohol present in the body.Depending on the amount of alcohol has been consumed, the traditional methodology typically reveals alcohol consumption that has taken place within the past few hours.The presence of EtG in the urine, alternatively, demonstrates that ethanol alcohol was ingested within the past 3 or 4 days, or roughly 80 hours after the ethanol alcohol has been metabolized by the body.
80 Hour Test for Alcohol: Conclusion 
It is this 80-hour period of time that has given this alcohol test the following name: the 80 hour test for alcohol.As a result of the above facts, it can be determined that a urine alcohol test employing EtG is a more accurate indicator of the recent consumption of alcohol as opposed to simply measuring for the existence of ethanol alcohol.
In addition to EtG, recent scientific studies have identified ethyl sulfate (EtS) as a second specific metabolite or biomarker of ethanol. For this reason, Georgia On-Site Labs tests and reports EtS, in conjunction with EtG, to confirm recent ethanol ingestion or exposure. The detection of EtG and EtS offers greater sensitivity and accuracy for determination of recent ethanol ingestion, than by detection of either biomarker alone.
Georgia On-Site Lab Testing utilizes the most sophisticated, sensitive and specific equipment and technology available, LC/MS/MS (liquid chromatography/mass spectrometry/mass spectrometry), to screen confirm and quantitate EtG/EtS. This methodology provides highly accurate alcohol biomarker test results.

Features and Benefits

Ideal for zero tolerance and abstinence situations. Strong indicator of ethanol ingestion within the previous 3 to 4 days. Allows monitoring in alcohol treatment programs and acts as an early warning system to detect trends towards relapse. Tests performed by LC/MS/MS on state of the art equipment. EtG/EtS tests may be run on urine specimens in conjunction with other drug testing panels. Fast turn-around time from receipt of specimen (48 hours 1 negative, 72 hours positive).

How long can EtG/EtS be detected in urine?

Traditional laboratory methods detect the actual ethanol in the body, which reflects current use within the past few hours (depending on how much is ingested). The presence of EtG/EtS in urine indicates that ethanol was ingested within the previous 3 to 4 days, or approximately 80 hours after ethanol has been ingested. Therefore, EtG/EtS is a more accurate indicator of the recent ingestion of ethanol than measuring for the presence of ethanol itself.

Georgia On-Site Labs offers numerous advantages to your agency including:

  • Extensive experience in performing forensic toxicology analysis for alcohol and drugs of abuse
  • Highly qualified scientific staff State of the art instrumentation for the detection of alcohol and drugs of abuse
  • Excellent client services, and extensive quality assurance and quality control procedures that help to ensure accurate results.drug and alcohol testing

Alcohol in Blood Tests

When screening for alcohol in blood, tests have been developed that are the most accurate and reliable of all current alcohol testing methods.Stated in another way, regarding the validity of the various alcohol testing procedures in use today, alcohol in blood tests are the most precise and the most trustworthy method for testing an individual’s blood alcohol level or his or her blood alcohol concentration (BAC).
In spite of their reliability and accuracy, however, blood alcohol tests are the least frequently used alcohol testing method due to their relatively high cost and their high level of intrusiveness.

The Main Characteristics of Blood Alcohol Tests

Blood alcohol tests are also called alcohol blood tests and blood tests for alcohol and have the following characteristics:
  • They are the most accurate method for testing a person’s blood alcohol concentration.
  • They are the most expensive method to testing a person’s blood alcohol content. 
  • They are the most intrusive method for testing blood alcohol level. 
  • Due mainly to their high cost and to their intrusiveness, blood tests are the least common method for testing a person’s blood alcohol concentration (BAC).
As far as the validity of alcohol in blood tests are concerned, blood alcohol tests are the most accurate method in use today for testing a person’s blood alcohol content (also known as the blood alcohol concentration or blood alcohol level).

Alcohol in Blood Tests: Conclusion

As stated above, when organizations and companies screen for alcohol in blood, tests have been developed that are the most reliable and accurate of all the available alcohol testing procedures.
Interestingly, due to their high level of intrusiveness and their high cost, blood alcohol tests (alcohol called blood alcohol tests and blood tests for alcohol) are the least frequently used alcohol testing method currently in use today, despite their high level of accuracy.
