How Blood Tests Work
To properly perform blood alcohol tests, a person who is specially trained must draw blood from your body into a specifically prepared vial. The blood is then analyzed to determine whether or not it contains ethanol, or alcohol. The proportion of ethanol molecules in the blood is then measured to calculate your blood alcohol concentration.
Potential Problems with Blood Tests
Besides the numerous health risks associated with improper blood-drawing techniques, there are several other potential problems that can affect the results of your test. These issues include:
- Using rubbing alcohol to prep the site for needle insertion
- Failing to place an anticoagulant in the sample
- Forgetting to include a preservative in the vial of blood
- Medications that you may be taking that influence the test results
- Health conditions like diabetic ketoacidosis that can skew the results
These mistakes can compromise the test results and can mean the difference between a wrongful DWI charge and acquittal you deserve.
