Making Life Changes to Avoid Incorrect Test Results

A person might have to regularly provide breath test samples to comply with bond or probation requirements. Also, a restricted driver’s license can require in-car breath samples in an alcohol interlock device. Modern breath test devices are typically hand-held and connect remotely to the internet. Despite advertisements and representations that these devices can distinguish between false and legitimate positive alcohol samples, they are notorious for inaccurate test results. To avoid potential issues with a judge or the Michigan Department of State, it helps if you can avoid products known to cause false-positive breath test results.

  • Non-alcohol beer and wine
  • Foods cooked with alcohol
  • Sugary pastries such as cinnamon rolls and honeybuns

Medications to Avoid if Possible

Most prescription and over-the-counter medications do not contain alcohol. In most cases, the defendant must switch medicines that contain alcohol to non-alcohol medications. Make sure you ask your doctor about non-alcohol alternatives. If there is no alternative to a drug that contains alcohol, speak to your criminal defense lawyer immediately about the situation so that they can bring the issue before your judge before a violation of bond or probation.

  • Cough syrup and cold/flu medication
  • Canker sore and toothache gels and liquids
  • Sleep aids
  • Vitamins
  • Asthma inhalers

Health Conditions Can Cause a False Positive

Certain health conditions could also set off a breath test. If you test positive and haven’t consumed any product that contains alcohol, the result could be due to a known or unknown health condition. If this happens, it is vital that you see a doctor right away to determine any possible cause for the inaccurate reading. Examples of health conditions that can cause an issue with a breath testing device include:

  • Diabetes
  • Heart disease
  • Heartburn
  • Fever
  • Liver disease
  • Gum disease
  • Acid reflux

“What should I do if I have a false positive test?”

If you experience a false-positive test result, contact your lawyer immediately. You must get an independent alcohol test as soon as possible to demonstrate that you did not consume an alcoholic beverage. You should find out in advance if you are required to submit to a specific alcohol test in the event of a false positive. For example, if you are required to get an ethyl glucuronide (EtG) test and do a PBT test instead, a judge or DAAD hearing officer might not accept that negative result as evidence. Always follow the rules as outlined in any court or administrative order. If no rule says otherwise, it is usually best to get an EtG test. Most drug and alcohol testing facilities offer EtG tests. An EtG test can determine if you’ve consumed alcohol within 48 to 72 hours of the test. Courts tend to accept the results of legitimate testing facilities. If your lawyer tells you to do something different than this blog, follow your lawyer’s advice. If you do not trust your lawyer’s advice, it is time to get a new lawyer.
