What agreement must two consecutive tests be within to be valid?

For the Intoxilyzer 8000, two consecutive breath alcohol tests must produce results that are within a specific range to be considered valid. The accepted standard is that the results of these tests should not differ by more than 0.02 grams per deciliter (g/dL) of blood alcohol concentration. This standard ensures that the readings are consistent and reliable, minimizing the possibility of errors or anomalies that could arise from variations in individual test administrations or the physiological factors affecting breath alcohol measurement.

When tests exceed this margin of 0.02, it could indicate potential issues with the testing process, such as problems with the instrument calibration, environmental factors affecting the readings, or inconsistent testing by the operator. Adhering to this standard is essential for ensuring the integrity of the results and the overall process of alcohol testing in law enforcement and legal settings.
