DUI Blood Alcohol Content

DUI Blood Test

Forensic evidence in DUI cases can include blood alcohol concentration conclusions based on breath tests and tests of many kinds of bodily substances. Some of the bodily substances commonly tested to determine alcohol levels or presence of drugs in a driver's body include:

  • blood
  • serum (a derivative of blood)
  • plasma (a derivative of blood)
  • urine
  • vitreous fluid

If you have been charged with DUI based on forensic testing for alcohol levels, you need an attorney who understands not whether the alcohol testing method was reliable and how the test data should be interpreted. Patrick Ferris has encountered many Coffee County, Douglas, GA, and Georgia DUI cases involving erroneous reporting of drug and alcohol concentrations in the blood, and even cases involving erroneous reporting of the bodily substance that was tested.

If you have been charged with DUI based on a test of your blood, breath, urine, or other bodily substances, contact our office to discuss your case with Coffee County DUI defense lawyer Patrick Ferris.

Blood Alcohol Content (BAC)

Blood alcohol content (BAC) is the amount of alcohol in your blood. A BAC test actually measures the weight of alcohol in a certain volume of your blood, expressed as a percentage. The greater the level of alcohol in your blood, the more your driving will be impaired.

Although most Coffee County, Georgia laws provide that a blood alcohol content of .08% is considered legally intoxicated, some studies show that a blood alcohol content as low as .02% affects a person's ability to drive and increases the likelihood of an accident. The probability of a crash begins to increase significantly at a blood alcohol content of .05% and climbs rapidly above .08%. The science of blood alcohol content varies between men and women. A female DUI charge needs to be handled differently than if it happens to a male. If you are a woman facing a DUI charge, tou need an experienced DUI lawyer that can navigate intricate DUI laws and processes. Call Patrick Ferris today at (912) 384-1099.
