Blood & Breath Tests in California DUI Cases

Have you failed a blood or breath test?

If you have been charged with a DUI in Los Angeles, it is probably because you failed a blood or a breath test administered by a police officer. Blood and breath tests are the most commonly used means of determining a person's blood alcohol concentration in the state of California. State laws forbid a person to drive if their blood alcohol concentration (BAC) is 0.08% or above.

f you have been subjected to a blood or breath test and have failed, you may greatly benefit from the help of a Los Angeles criminal defense attorney.

DUI Screening Test Errors

If you have been charged with a DUI, the prosecution must be able to prove that your BAC at the time of the offense was above 0.08%. Scientific research shows that the use of breath tests to determine BAC may not be the best method because results can differ in a given individual from time to time. Breath and blood tests can have different readings for different people, depending upon:

  • Weight
  • Metabolism
  • Sex
  • Body temperature
  • How much breath is blown into a Breathalyzer
  • Rate of alcohol absorption

In addition to errors on the screening device, the person administering the test may also contribute to a wrong test result. If the officer reads the result incorrectly or if the machine is not properly calibrated, you may be falsely accused with driving under the influence. At Law Offices of David D. Diamond, we are familiar with the many failures of the breath test, and we have defended countless clients against faulty DUI charges. When you hire an attorney from our firm, you can be confident that you are investing in the best DUI defense for your situation.
