About Blood & Breath Tests in Gwinnett County

(404) 816-4440

When law enforcement is suspicious that you are driving under the influence of alcohol, they will not only test you with field sobriety tests, they will test your blood or breath for the blood alcohol concentration (BAC) level. The normal testing equipment is the “Intoxilizer 5000”. This breath-testing device is not the most current or updated, but is the only one allowed by state law. Law enforcement can take two samples of two tests each, and if the samples vary by more than .02%, not all of the results cannot be used in court. The lowest reading will be used in the case against you.

Though these test results are used in court, there are many factors that can cause the readings to be partially to wildly inaccurate. For example, the temperature of the body changes the readings on the breath test. If you are diabetic or are on a high-protein diet, you could also see false readings. These problems come into play if you have had the misfortune of being arrested and charged with DUI and register at .08% BAC or higher for an adult, .02% BAC or higher for those under 21 and for those who operate a commercial vehicle the limit is .04% or higher. A Gwinnett County DUI lawyer may be able to help.

There is no test on earth that is 100% accurate even in in the best of conditions. When the breath test evidence is used against you in court, the legal team at the firm will thoroughly review how the testing was done and the calibration of the testing equipment at the time, as well as how the test was administered.

Blood test evidence can also be flawed based on how the blood was drawn (for example, if alcohol was used to swab the arm prior to drawing blood which could affect the reading). How the lab analyzed the blood evidence is important, as some labs test only the plasma, which can increase the concentration of alcohol as the volume of the sample is reduced in plasma testing.
