The State of Georgia uses technology designed in the 1970's to conduct breath tests on its citizens and guests. That should be enough said, but I will explain further. The Intoxilyzer 5000 was designed in the 1970's and was last updated (significantly) in the 1980's. Several more advanced and accurate devices are on the market today. Many factors can contribute to an inaccurate result, including (but not limited to) residual alcohol in the mouth, Radio Frequency Interference, exposure to solvents and chemicals, and an inaccurate calibration of the device. In fact, Georgia is so concerned with accuracy that when a person is arrested for DUI, they calibrate the machine once every 90 days!! Other States calibrate the machine every time a suspect takes the test. Never assume the accuracy of a Georgia Breath Test. Have my office check to see if the machine was in working order when you took your breath test.
