Breath and Blood Tests

Truth Behind Breath and Blood Tests

DWI Attorney in San Antonio

Similar to field sobriety tests, you have the right to refuse taking a breath or blood test. Law enforcement officers often use chemical tests to determine your blood alcohol content when they pull you over on the suspicion of drunk driving. There are two types of machines they use to measure the alcohol level in your breath: Intoxilyzer 5000 and Breathalyzer. For the blood test, they simply draw blood from you. While these tests may seem like foolproof methods, they're not.

Don’t assume that because you were given a breath or blood test in the course of a DWI arrest you are guilty of the charges against you. Working with a San Antonio DWI lawyer during your arrest can help you find out the myriad of ways that things could have gone wrong, especially when determining your supposed blood alcohol content.

What Can Go Wrong During BAC Testing?

There are many factors that come into play when performing either a breath or blood test. The procedures must be perfectly carried out to ensure the accuracy of the results. As you may know, not all law enforcement officers are perfect. Everything from calibration problems to lack of probable cause may contribute to the effectiveness of the test.

  • Some factors that can affect the results from a breath or blood test include:
  • Improper calibration of the machine
  • Poor maintenance or administration
  • Lack of a search warrant for blood tests
  • Qualifications of the person administering the test
  • Procedures performed to conduct the test
