What are the Problems with Blood Alcohol Testing?

In Texas, the legal blood alcohol concentration (BAC) limit for operating a motor vehicle is .08. Thus, it is easy to assume that blood testing is the most accurate way to determine a person’s BAC. However, there are some problems that can skew the results, such as:

• Using alcohol to clean the site of the needle insertion
• Taking medications that contain alcohol, such as some cough syrups
• Improperly storing the blood
• Failing to place anticoagulants and preservatives in the blood sample

Unfortunately, even these simple problems can lead to mistakes with your BAC results. This may make it seem as if you were driving while intoxicated while you were actually under the legal limit.
