Breath & Blood Tests in DUI Charges in San Diego

San Diego DUI Attorney

Those who are pulled over by law enforcement in San Diego for suspicion of DUI are usually asked to take a series of field sobriety tests. This is in order to get more evidence and support the DUI stop, arrest and charge. In fact, you are not required under state law to submit to field sobriety testing, but you are required to take a blood or breath test when asked, or you will have an automatic license suspension among other serious repercussions. A San Diego DUI attorney from Mark R. De Yoe, APLC should be contacted immediately if you are facing charges. The defense of the case starts the moment you have been arrested.

Defending DUI Charges Based upon Breath or Blood Test Evidence

There are a large number of potential errors in both blood and breath testing, including wrongly administered tests, faulty equipment, and lab errors. One of the most difficult situations is the matter of breath testing. The way the process has been developed over the years is based upon testing that assumes that every individual has a "conversion ratio" of 2100 to 1 when the body processes alcohol. There are many scientific papers that refute this legislatively imposed ratio; in fact, and individual's partition ratio of alcohol can vary widely, even from moment to moment, making the situation even more complex.

There are other factors that could heavily affect testing results of breath tests, and your case should be evaluated without delay if you were arrested after a breathalyzer test. Some testing units that are in circulation have a history of errors, and law enforcement may have failed to correctly administer the test. Blood test evidence is also open to serious errors, including in factors such as how the blood was drawn, how it was preserved and how the lab performed the test. The key issue in a DUI charge is BAC evidence. You deserve to have every opportunity to fight back if you are accused of DUI. At Mark R. De Yoe, APLC, the attorney has extensive scientific knowledge in both breath and blood tests and should evaluate your case immediately.
