Blood Test Defense Lawyer in El Cajon

El Cajon DUI Charges and Blood Alcohol Testing

A blood test is one of the ways that law enforcement may determine a driver's blood alcohol concentration after a DUI arrest. This is often a key part of building a case against a driver and seeking a conviction for driving under the influence of alcohol and/or drugs. Blood tests are considered to be more accurate than breath tests in determining a driver's blood alcohol level and are usually the way law enforcement will test a driver for controlled substances.

Did you submit to a blood test after an arrest for drunk driving? An El Cajon DUI defense attorney at Superior Law Center can talk to you about your case and can offer helpful information that will guide you toward the right decisions about your charges and options. Even though you took a blood test and allegedly had a blood alcohol concentration of .08% or were told that drugs were found in your system, this does not mean that you should be convicted. A lawyer experienced in challenging blood test evidence can investigate the matter and even conduct an independent analysis of the blood sample to contest its validity.

How does a blood test work?

A blood test is administered by taking a blood sample from a driver suspected of DUI. The test must be administered by a qualified professional and the sample must be handled properly, including mixing it with anticoagulants and preservatives. If the sample is mishandled, administered or mixed improperly or carried out by an untrained individual, this may be grounds to question the reliability of the sample. An independent analysis of the sample may even reveal that the driver's blood alcohol concentration was in fact below the legal limit.

These are just a few examples of potential ways to challenge blood testing. To discuss your particular case and find out how we can help you, contact an El Cajon Blood Test Defense Lawyer at our firm.
