Defense for DUI in Arizona: Inaccurate DUI Blood Tests
AZ DUI blood testing is considered to be the most accurate form of testing for determining AZ DUI blood alcohol content (BAC). However, that does not change the fact that many errors can still occur in the Arizona DUI blood testing process. Arizona DUI laws require that specific protocol and procedures be followed for blood collection. If these protocols are not strictly followed, and standards met, it could cause blood test results to be inaccurate. In that event, the blood evidence may be thrown out, leading to a case dismissal of your Arizona DUI.
The following are some factors that could affect the accuracy of blood test results:
1. Use of Contaminated or faulty medical equipment
2. Improper method used to draw the blood
3. Improper storage or transportation of the blood sample
4. If a test subject has anticoagulants present in their blood, this can result in an inflated and inaccurate BAC test result
5. The drug testing or narcotic identification kit could be expired
6. Rubbing alcohol could contaminate the blood sample
7. Too much preservative in the vacuum tube could result in an inaccurate reading
8. Lab technicians could mix in too much salt which will artificially inflate results
9. Results could be inflated if only blood serum or plasma is tested instead of whole blood.
If you are stopped for suspicion of driving impaired and the police request and you agree to a blood test then only a person trained in blood withdrawal can take your blood sample. The person responsible should be careful not to allow alcohol from a swab to contaminate the blood drawn.
Arizona DUI prosecutors claim that blood testing machines are accurate to within 5%. But many Arizona DUI defense attorneys and experts will tell you that they are not nearly that accurate as they claim to be. Problems exist in operation error or sample collection procedures that can cause the results will be unreliable. Top Arizona DUI Attorneys recommend you request a second sample to be taken at the same time or as close as possible to the first, for your AZ DUI Lawyer to have retested independently for evidence in your Arizona DUI Defense.
