Breath Testing & Fresno DUI
There are many reasons for false breath test results. The 15-minute observation period mandated by Title 17 of the California Code of Regulations may not have been complied with, or you may have burped, regurgitated or vomited within 15-minutes of taking the test. Medical conditions (gastroesophageal reflux disease or laryngopharyngeal reflux) or dental work (dentures or bridgework which may trap mouth alcohol) could account for an inaccurate test result. The breath sample could have been tainted with mouth alcohol or the breath-testing device may not have been operating properly. Further, breath testing during the alcohol absorption phase can give a false high reading.
To combat your charge, our qualified Fresno DUI defense lawyer can check the calibration and accuracy logs for the breath machine to determine whether or not the results are accurate and can confirm whether the officer followed the training protocol.
Knowing the science of breath testing is vital, therefore you can depend on Wapner Jones, PC to utilize our knowledge in this area to better prove that your results were false. A general criminal law attorney is not sufficient for your DUI case: You need us because we know how to handle and investigate chemical testing.
Blood Testing & Fresno DUI
Following your blood test, your blood sample can be drawn or stored improperly, or it may be tainted with improper levels of preservatives and anti-coagulant, all of which can give a false BAC result. In addition, the labs that run the tests do several tests at the same time using the same apparatus. Thus, sometimes the vials get mixed up. If the blood test results are truly suspect, a DUI attorney who knows GC-FID and GC-MS (methods used to analyze BAC levels) will be able to find out why. The attorneys at Wapner Jones, PC train at the Axion Laboratory in Chicago to learn how to defeat this test, therefore we have the key insider knowledge you need to overcome your DUI charge.
