New Jersey DWI Blood Test Inaccuracies
Breath, blood and urine tests for blood alcohol content can yield inaccurate results and cause good people to be wrongly convicted of drunk driving charges.
The following are just a few of the defenses your attorney may explore to challenge the validity of your DWI blood test results:
- Equipment: Was the blood testing equipment faulty, broken, or not maintained properly?
- Technician: Was the phlebotomist properly certified? Did he or she correctly follow procedures?
- Time Delay: If the blood test was taken too long after your arrest, your “rising blood alcohol” level will not accurately reflect your BAC at the time of driving.
- Chain-of-custody: A break in the chain-of-custody of the blood sample could possibly result in sample switching or contamination.
- Fermentation: If the blood sample was left out and fermented after it was collected, it will create its own alcohol and yielding falsely high results.
- Rubbing Alcohol: If the phlebotomist sterilized your arm with an alcohol pad, this could have caused an elevated BAC reading.
- Storage: If the blood was stored improperly, or there were inadequate levels of anticoagulants and preservatives in the vial, the results could be inaccurate.
