Breath, Blood and Urine Tests
DUI charges from a BrAC or BAC Test
If you blow over the .08 limit, or have a blood test result over .08, don't automatically assume that you cannot fight your DUI case. Breath and blood tests deliver invalid results frequently. Breath and blood testing equipment may not be calibrated properly, the operator may have had inadequate training or the blood samples may have been obtained improperly.

How We Challenge Chemical Test Results
While improper police procedures are the predominant cause of invalid test results, there may be specific problems with each method of testing. We have defended thousands of cases where we challenged chemical tests with success.
Breath testing instruments are sensitive and are required to be properly calibrated before and after each use. In addition, police must use a very specific procedure in order for the resutls to be accurate.
Blood test samples could be contaminated during processing in the lab or even at the point of collection. Blood alcohol content may still rise after a police stop, so your BAC during the time of driving may be lower than when the sample was collected.
The urine test is less accurate than the blood or breath tests, which is why the trend is now to allow use of the test only when the blood and breath tests are unavailable.When a person is arrested for driving under the influence of drugs, prosecutors may use the urine test results to prove intoxication.
The problem with this approach is that urine tests are unreliable in that they cannot determine when a drug was used. Urine analysis only detects metabolites (traces of previously ingested drugs) rather than the actual drug itself. So, depending on the drug, and the levels present, it is difficult to determine whether the drug was present in person's system at the time of driving.
