Alcohol & Drug Tests

Personal Breathalyzer

A personal breathalyzer is a helpful product that tests your BAC (blood alcohol content). A home breathalyzer may help you determine if you are within the legal limit of blood alcohol content. Keep in mind that the legal limit varies from state to state. For a compact, on-the-go option, try a keychain breathalyzer. A keychain breathalyzer can be attached to your car keys, so you&#;ll never be without it! You can also purchase a slightly larger home breathalyzer test and replacement mouthpieces so that more than one person can use the unit.

Home Drug Test Kits

Home drug tests are tools that test for specific drugs in a person&#;s system. Most at home drug tests will offer a quick, at home result as well as a mail-away laboratory confirmation test that is either included in the price or will be billable later. When selecting a home drug test, it is important to make sure that the selected kit tests for the specific drug or drugs that you are concerned about. You should also keep in mind that while manufacturers do all they can to deliver reliable results, the nature of the product means that home drug tests are not always accurate. It is important to be aware that you may get an incorrect result. This can be due to a variety of factors, such as: the person being tested attempting to cheat or otherwise influence the results; the chemicals in the test expiring without you realizing; user error when administering or storing the test; unforeseen interactions with other substances consumed, such as certain types of food or drinks; and certain prescribed medications that may show up on the drug test even when taken responsibly. It is possible to get a false negative or a false positive from your at home drug test. Until you have confirmed the results of a home drug test kit with either a laboratory, your doctor, or both, you should refrain from taking any action aside from seeking out confirmation. Once the results have been confirmed, you should talk to your doctor about what the appropriate next steps should be.

OTC Drug Test

Many parents are interested in using an over the counter drug test to either check if their teenage children are taking drugs, or to prevent them from taking drugs by using the test as a deterrent, reasoning that if they know they will be tested, teens may be less likely to start using drugs. While home drug testing can be helpful in some cases, it is important to know that the American Academy of Pediatricians (AAP) does not advocate at home drug testing. Furthermore, the AAP stresses the importance of making early intervention and treatment options available if your teen does indeed test positive for drugs, rather than simply punishing them for using. If the person you are testing is an adult, your response should still be the same - it is equally important to offer the user resources and avenues of support in a respectful manner that ensures the safety, health, and wellbeing of both parties.

Positive Drug Test

If you get a positive result on a home drug test, your first action should always be to verify the results with a lab or your doctor. If it turns out that your loved one is using drugs, talk to your doctor about next steps. He or she will be able to offer you guidance about appropriate resources and treatment options that are available in your area. Be kind, but firm, and do not take any actions that will put either yourself or your loved one in danger. If you are dealing with a complicated situation, do not hesitate to seek help and support. Your doctor or a local agency are good places to start your search.

Urine Test for Alcohol: Types, Limits, Detection Windows

Urine tests can detect alcohol metabolites in your system long after you&#;ve had your last drink.

When your body processes alcohol, it produces alcohol metabolites. These metabolites stick around in the body even after you feel sober.

Though your body can eliminate alcohol relatively quickly, alcohol metabolites remain in your system longer. Urine tests can check for alcohol and alcohol metabolites in your urine.

Most urine tests detect alcohol up to 12 hours after your last drink. Advanced urine tests, however, may be able to detect alcohol 24 hours after drinking.

Types of urine tests and how they work

There are a few types of urine tests, and some are more accurate than others.

Because alcohol metabolites stay in the body long after alcohol is eliminated, tests that find metabolites will have a more extended detection period.

The urine tests for alcohol are:

  • Ethanol urine test: This test measures the ethanol (alcohol) in urine. Because ethanol is eliminated through the body quickly, these tests can detect very recent use only.
  • Ethyl glucuronide (EtG) urine test: EtG is an alcohol metabolite. Although EtG tests usually have a detection window of about 24 to 72 hours, the metabolite may be detected for up to 80 hours after alcohol use, especially with heavy drinking.
  • Ethyl sulfate (EtS) urine test: EtS is another metabolite. EtS urine tests usually guarantee accuracy only in the first 24 hours. But much like EtG, EtS can be detected in urine about 80 hours after heavy alcohol use.

Windows of detection in urine tests

The window of detection for urine tests will vary depending on the type of test:

  • Ethanol urine tests: 12 hours
  • Ethyl glucuronide (EtG) urine tests: 24&#;72 hours
  • Ethyl sulfate (EtS) urine test: 24&#;72 hours

If you&#;ve recently consumed a large amount of alcohol, the window of detection may be longer than if you had a single drink.

Tips to ensure accurate results

Although urine tests are a relatively inexpensive and noninvasive way to test for alcohol, they may be inaccurate in some cases. It&#;s possible to get a false positive on a urine alcohol test.

To ensure accurate results, it&#;s essential to:

  • Make sure your hands are clean before urinating or handling a urine sample.
  • If using a container, ensure that it&#;s clean.
  • Ensure the test is sealed and hasn&#;t expired.
  • Clean your external genitalia with a moist cloth. If you&#;re being tested under supervision, they will usually provide a towelette for you.

Before taking a urine alcohol test, it&#;s best to avoid:

  • mouthwash or breath spray that contains alcohol
  • &#;non-alcoholic&#; beers and wines, which may contain trace amounts of alcohol
  • kombucha and fermented foods, which may contain trace amounts of alcohol
  • alcohol-based sanitizer and cosmetics
  • cleaning products that contain alcohol

Even if used externally and not ingested, it&#;s possible that products containing alcohol will cause you to test positive for alcohol consumption. It&#;s best to avoid anything that contains alcohol, even in tiny amounts.

Understanding urine test results

Nowadays, EtG urine tests are one of the most common ways to check for alcohol consumption. They don&#;t only test whether you have or haven&#;t used alcohol &#; they may also indicate how much recent drinking has taken place.

For an EtG or EtS urine test:

  • A high positive result (>1,000ng/mL) may indicate same-day drinking or heavy drinking on the previous day
  • A low positive result (500 to 1,000ng/mL) may indicate drinking the previous day or day before, light drinking within the last 24 hours, or recent exposure to alcohol-based products
  • A very low positive result (100 to 500 ng/mL) may indicate heavy drinking a few days previously, recent light drinking, or recent exposure to alcohol-based products

If you have trouble interpreting your results, consider consulting a medical professional.

If you disagree with your test results, you may be able to request a re-test from the entity that requested the test (for example, the court, your employer, or your doctor).

Urine test limitations

Urine tests are a cost-effective way to test for recent drinking.

But they do have their limitations, specifically:

  • The window of detection is relatively short.
  • It&#;s possible to dilute urine or substitute the sample with another person&#;s urine.
  • The person being tested usually needs to be observed, which can be uncomfortable.

As with many tests, urine tests are not accurate 100% of the time. A false negative is possible. Someone may test negative for drinking alcohol when they have had alcohol recently.

EtG urine tests can detect recent drinking with a 70% accuracy &#; although one study showed that they&#;re about 85% accurate for moderate to heavy drinking.

Urine test alternatives 

Urine tests aren&#;t the only way to verify whether someone has consumed alcohol. Other methods &#; breath, hair, and blood tests &#; can detect recent alcohol consumption.

Breath tests for alcohol usually detect consumption within the past 4 to 6 hours. A Breathalyzer may measure your blood alcohol content (BAC). As such, it doesn&#;t test only whether you&#;ve had alcohol but how much you&#;ve had.

A hair follicle test can detect alcohol use within the past 90 days.

Blood tests can also be used to measure your BAC. Traditional tests can accurately detect alcohol consumption within the past 12 hours, and it can detect how much you&#;ve consumed.

There are many types of blood tests. They can also test for EtG and EtS. A carbohydrate-deficient transferrin (CDT) test can detect heavy alcohol use.

A phosphatidylethanol (PEth) blood test &#; a newer but highly sensitive way to test for alcohol use &#; measures PEth, which is formed when your body processes ethanol.

A PEth test may be able to detect alcohol consumption within the previous 1 to 3 weeks. In one study with 16 participants, PEth was detected in participants&#; blood for 3 to 12 days after they had one drink. Another study noted that PEth may be detected in your blood up to 60 days after heavy, prolonged alcohol use.

The bottom line

Urine tests can detect alcohol or alcohol metabolites in your urine. Generally, these are accurate for 12 to 24 hours, although you may test positive up to 80 hours after drinking alcohol.

There are instances where urine alcohol tests may be inaccurate. In some cases, alternative tests &#; such as a breath, hair, or blood test &#; may be more appropriate and valuable.
