Can a Medical Condition Affect My BAC Reading?

Comments (0)
Sometimes, a medical condition can prevent you from performing well on a field sobriety test, preliminary breath test or even a breathalyzer test. Certain medical conditions can cause a false blood-alcohol reading.

Many forensic consultants, doctors, pharmacists and attorneys agree that there are problems with the breath alcohol test and certain conditions that can cause false readings and lead to a Virginia DUI arrest. There are also medical conditions that can affect a person's performance on a field sobriety test.

These conditions include:
  • Acid Reflux
  • Diabetes
  • Inner Ear Infections
  • Attention Deficit Disorder
  • Heart Disease
  • Flu or Fever
  • Gum Disease
  • And more 
When a person with one of these conditions is stopped at a DUI checkpoint or pulled over by law enforcement and asked to take a field sobriety test or a chemical test of the breath, there are certain defenses that a Virginia drunk driving attorney who specializes in this area will know. Having knowledge about chemistry, biology, anatomy, pharmacology and physics all help a DUI defense attorney put together the proper defense in your case.

The field sobriety tests and breath tests were created for the normal, healthy person. If you have a medical condition, the accuracy of the testing will be flawed and your attorney may be able to convince a jury that your BAC test was a false positive. A breathalyzer has produced false readings before, and is not always considered accurate in determining proper blood-alcohol content, as there are variables like medical conditions that can affect the readings.
