Seattle Breath & Blood Tests

Washington DUI Lawyers

When a person is pulled over for drunk driving in Seattle, a breath test can be administered by a Washington law official in order to determine whether or not the person is intoxicated.  A breath test will measure the amount of alcohol present in the blood stream and is a way of determining if a person is over the legal limit, which in Washington is .08 percent.  There may be some circumstances in which a blood draw can be administered to determine BAC, however, breath tests are the majority. The DUI defense attorneys at our firm have seen many cases where the results from a blood or breath test are wrong.  Many clients are surprised to learn that there are many factors which can affect the outcome of their blood or breath test, and if any of these were present in their situation, their Seattle DUI lawyer will find it.

Breath Tests

There are many things that can go wrong during a breath test that can lead to an inaccurate BAC level. Certain health issues like emphysema, GERD, asthma, bronchitis and diabetes can cause inaccurate breath test results. Technical issues can occur with the testing equipment because breathalyzer machines have not been maintained properly, improper testing procedures have been used, or outside interferences such as radio frequency or pollution are present.   

Blood Tests

There are many factors which can lead to an inaccurate BAC when a blood test is performed.  For example, if the medical equipment used is contaminated or faulty, or if the client has any existing medical conditions, the BAC from the blood test can be false.  It can be very beneficial to have a Seattle DUI attorney who will work hard to find any discrepancies in a blood test that may lead to a dismissal of charges.
