Breath & Blood Tests

Breath & Blood Tests Defense Attorney in Bakersfield

Providing Skilled & Aggressive Legal Representation

If you are arrested on any DUI charge in California, that usually means you failed an administered breath or blood test. If you register a blood alcohol concentration (BAC) level above legal limit of .08% or higher, an arrest will be made. The usual type of breath test is a "breathalyzer test."

In Bakersfield, law enforcement uses tests that have often been found "inherently unreliable". This test uses your breath to measure the BAC level. The formulas used in the machine to compare your breath alcohol level to your blood alcohol level are commonly inaccurate, which is why you must challenge those tests.


If you believe this may be the case in your situation, it is crucial that you contact a qualified Bakersfield breath and blood test attorney. Call our office at (661) 874-1325 today. 


Facts About Blood Tests

While blood tests are more accurate, no test in existence is 100% accurate. In some incidents, the crime lab may intentionally order test tubes that regularly contain less than 1/5 the required amount of preservative to insure the blood does not ferment.

They intentionally wait for days, weeks, or sometimes months before testing which allows the fermentation process to occur. That fermentation process, as in beer or wine, produces higher levels of alcohol in your blood.

Middlebrook & Associates can enlist the help of an independent toxicologist to support your defense if you have been administered a blood test that resulted in a DUI charge.

Challenging Evidence

The suppression of evidence is part of what an experienced and creative DUI lawyer will do to defend you. If the evidence against you is in question, it can be challenged in court. These court challenges have resulted in hundreds of cases where the charges were completely dismissed.

The equipment used in the breath testing and blood testing is required to have been maintained and checked to see if this maintenance has been properly done. A machine is only accurate if measured against a known standard. If the specific device used has a history of error, this can also be brought to the attention of the court.

There are many factors that can influence BAC tests, such as:

  • A physical or medical condition
  • The incorrect administration of the test
  • A faulty reading on any equipment used.

Any evidence against you will be carefully reviewed by our firm to aggressively fight your charges. Regardless of your circumstances, it is crucial that you speak with a legal professional right away.

  • “Highly recommended!”
    I was impressed with the results of my case and do not feel another law firm would have reached the outcome that they did. They needed little communication from me and handled everything without me needing to be present. They answered when I had questions and completed my case quickly.

  • “Highly professional and effective.”
    I'm a civil trial lawyer practicing in another state. In 2020, after a questionable traffic stop, my daughter was arrested for DUI. Our family engaged Middlebrook & Associates to assist her. They identified weaknesses in the State's case and formulated a trial strategy. While waiting for trial, they prevailed in the administrative proceeding, allowing my daughter to retain her driver's license. On the first day of trial, I could tell Middlebrook & Associates had the respect of the trial judge and prosecutor. They developed an excellent rapport with the jury and demonstrated deep understanding of the science related to DUI cases. Their cross-examination of the arresting officer was respectful yet effective. The jury acquitted my daughter on one charge and deadlocked on the other, leading to an acceptable plea agreement and eventual dismissal and expungement of all charges. We are very grateful to Middlebrook & Associates for their highly professional handling of our daughter's case. I highly recommend them.

  • “We are very grateful to Mr. Middlebrook for his extremely professional handling of our daughter’s case”
    By way of background, I am a civil trial lawyer who practices law in another state. In 2020, after a questionable traffic stop, my daughter was arrested for DUI. Our family engaged Mr. Middlebrook to assist her. After he reviewed the evidence, Mr. Middlebrook identified the weaknesses in the State’s case and formulated a trial strategy to include the retention of an appropriate expert witness. While waiting for trial, Mr. Middlebrook prevailed in the administrative proceeding allowing my daughter to retain her driver’s license pending trial. After plea negotiations fell through, we went to trial on the criminal case. I have over 35 years of experience in a courtroom and have tried dozens of cases to verdict. On the first day of trial, I could tell that Mr. Middlebrook had the respect of the trial judge and the prosecutor. He developed an excellent rapport with the jury. In his examination of the expert witnesses for each side, Mr. Middlebrook demonstrated a deep understanding of the science related to DUI cases. His cross-examination of the arresting officer was respectful while making the officer appear to be, at best, incompetent in his handling of the stop and administration of the breathalyzer test. The jury acquitted my daughter on one charge and deadlocked on the other. An acceptable plea agreement on the remaining charge was thereafter reached allowing for all charges to eventually be dismissed and expunged from her record. We are very grateful to Mr. Middlebrook for his extremely professional handling of our daughter’s case, and I highly recommend him.
