Alcohol Breath Tests
Breath testing is the most common way that law enforcement officers test for a DUI. The machines used, breathalyzers, measure the alcohol that is passed through blood vessels in the lungs, which can be measured on subject’s breath. Breathalyzer tests are considered accurate to be admitted in DWI prosecution.
Breathalyzers are not always accurate, and can result in readings that are not correct. It is important to know if the machine is working properly and has been maintained and calibrated. Other factors like a person’s diet, or the presence of environmental factors like pain, glue, and gasoline can skew results. Typically, breath tests are not as accurate as blood tests.
Alcohol Blood Tests
When an officer suspects a driver of being intoxicated, they will request to administer tests to confirm intoxication. As a driver, you must consent to have blood drawn. Refusing to take a blood test may have legal consequences, including suspension of driving privileges. Most states, including Missouri and Kansas, punish those who refuse blood alcohol tests with higher fines and longer jail terms than those comply.
A blood sample for BAC is typically more accurate than a breath or urine test, but lab testing errors can occur. A few things that can effect the accuracy of a blood alcohol test include:
- lack of sterilization
- coagulation
- refrigeration
- fermentation
- vial mix-ups
