Blood and Breathalyzer: False Positive Alcohol Test Results

The Law Office of Gregory Hagopian provides extensive driving under the influence (DUI) of alcohol or drugs representation. As a law firm dedicated to criminal defense for clients facing DUI charges, the firm's legal team has sophisticated knowledge of how to effectively challenge blood, breath and field sobriety tests results.

Life is not like a CSI episode.  Contact a qualified lawyer today at 559-302-9507 to help you challenge your test results.

The firm is led by Visalia criminal defense attorney  Gregory Hagopian — a former California prosecutor who has handled hundreds of cases. His unique insights into correct testing procedures enable him to evaluate clients' cases thoroughly to determine the best way to challenge the results in court. When evidence is obtained illegally or is contaminated, he will fight to have evidence suppressed and charges dismissed.

Thorough Evaluations

As a dedicated DUI defense lawyer, Mr. Hagopian has extensive experience evaluating and challenging DUI test results. His experience includes reviewing factors to determine if mistakes were made, including the following:

Field sobriety tests. He examines the entire scene, from lighting conditions and ground level to your clothing and possible distractions.

Blood tests. He will review the chain of custody. Blood samples need to be logged in by police, then logged out and handed to a person at the lab, who must take custody, test the sample, and officially return the sample back to the police. Additionally, he looks at Diabetes and medications affecting the BAC blood test results.

Breath tests. Breathalyzer machines must be calibrated and maintained according to state guidelines. Additionally, police officers must have proper training to administer the test and prepare the machine.

These tests are not 100 percent accurate, because many outside factors can cause contamination. For instance, if blood is not preserved properly, it can grow mold. Mold produces ethanol, which could produce a false positive result. Additionally, when breath tests are not conducted using state and federal guidelines or the machine is not in perfect working order, the results can be tainted.

Under certain situations, the firm can have blood samples retested by an independent lab. Forensic science experts can evaluate the evidence and procedures to demonstrate that evidence has been compromised.
