Breath & Blood Tests After a DUI/DWI

BAC is Measured by Testing Blood or Breath

When a driver is suspected of driving under the influence of alcohol, law enforcement officials may try to assess the driver's blood alcohol content (BAC) with the use of breath, blood and field sobriety tests. Breath and blood testing methods are used to determine the percentage or ratio of alcohol in a person's system. Anything above .08 percent in Kansas and Missouri is considered illegal and subject to arrest and being charged with DUI.

If you or someone you know has been arrested or is facing charges for DUI, based on the results of a breathalyzer or blood test, it is vital that a competent Kansas City DUI attorney be hired to protect your legal rights.

Common Test Errors

When drivers are pulled over under the suspicion of driving drunk, breathalyzer tests are most commonly used to determine BAC. What many people do not know is that where breath tests are concerned, there can be errors caused by several factors:

  • Surrounding temperature - cool air can concentrate breath, therefore making the BAC reading inaccurate
  • Improper breath blown - burping or weak breath from the mouth, not deep down in the lungs, can show a higher reading
  • Legal medicinal substances - diet and diabetic medications can result in an improper reading
  • Improperly calibrated breathalyzer machine - these sensitive machines, such as the Intoxilyzer 8000 require calibration, which may alter readings if they are not maintained
