DUI Chemical Testing in Fresno
What Are the Different Chemical Tests Used in the Central Valley?
There are two types of chemical testing: Breath and Blood. Urine used to
be a test used, but was dropped a few years ago. An experienced Fresno
DUI defense attorney will know how to point out the legitimate reasons
why a chemical test was faulty. The attorneys at Wapner Jones P.C. take
pride in the fact that they are more educated and knowledgeable regarding
blood and breath testing than any of their competitors. This is what separates
us from other attorneys and law firms. We spend many hours in training
and education around the country so we are better equipped to defend you.
As a result we have learned there are many ways to whittle away at the
trustworthiness of the prosecution's evidence and prevent them from
meeting their burden of proof beyond a reasonable doubt regarding the
Breath Testing & Fresno DUI
There are many reasons for falsely high breath tests. The 15-minute observation
period mandated by Title 17 of the California Code of Regulations may
not have been complied with, or the accused may have burped, regurgitated
or vomited within 15-minutes of taking the test. Medical conditions (Gastro
Esophageal Reflux Disease (GERD) or LPR) 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. Testing during the absorption
phase will give a false high reading. A qualified Fresno DUI defense lawyer
will check the calibration and accuracy logs for the machine to ascertain
whether or not the results are accurate, and will confirm whether the
officer even followed the training protocol. Knowing the science of breath
testing by your attorney is vitally important. Find out what their knowledge
level is before you hire an attorney. This is the reason why a general
criminal law attorney is not sufficient for your DUI case. It is imperative that you find a
DUI attorney who can deal with the chemical testing.
Blood Testing & Fresno DUI
The 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 of these at the same time using the same apparatus. Sometimes
the vials get mixed up. If the blood test results are truly suspect, a
DUI attorney who knows GC-FID and GC-MS will be able to find out why.
The attorneys at Wapner Jones P.C. train at the Axion Laboratory in Chicago
to learn how to defeat this test.
