Determining blood alcohol content (BAC) in drunk driving cases can rely on blood tests. However, like any scientific test, blood tests can produce errors. Several flaws can occur during the testing process, leading to inaccurate results. If you are facing a DWI charge and blood test results are part of the evidence against you, are you aware of the errors that could be hiding in your results?
Why reviewing blood tests matters
Blood tests can be prone to human error and equipment malfunction. Among the flaws that can occur during the testing process are:
- Contamination: Collecting blood samples improperly can contaminate them, leading to false positive results. For example, if the technician fails to properly sterilize the needle used to collect the sample, it can introduce foreign substances into the sample.
- Improper storage: Failing to store blood samples at the proper temperature or handle them correctly can cause them to degrade, leading to inaccurate results.
- Inadequate training: Technicians or analysts who are not properly trained may not follow proper protocols, leading to errors.
- Instrumental errors: Machines that analyze blood samples can malfunction or be improperly calibrated, leading to inaccurate results.
- Chain of custody issues: Failing to properly handle or store the blood sample can break the chain of custody, making it difficult to verify the integrity of the sample.
These possible flaws highlight the importance of reviewing blood test results and procedures because inaccurate results can lead to an unfair conviction. In Missouri, a DWI conviction can have serious consequences, including fines, imprisonment and license suspension.
Protecting your interests and rights
Knowing the potential flaws of blood tests in your drunk driving case is critical. However, going through the legal process can be challenging and overwhelming. By seeking guidance from an advocate, you may better protect your interests and rights as you navigate the legal system.
