DWI Blood Sample

A DWI conviction has serious and long-term ramifications that might follow you even after you’ve served your sentence. If you’ve been charged with DUI, you must approach the situation with the immediacy and severity that it warrants. This means enlisting the counsel of a tenacious and competent DWI defense attorney who can help you overcome the charge and prevent a conviction. A blood sample taken after DWI when the accused is in the hospital  under the influence of painkillers or anesthesia may be questionable and should be thrown out  as admissibility depends on consent.

According to the Texas Penal Code, DWI is one of the most severe misdemeanor offenses. Depending on the BAC, the fine may be up to $6,000, and even if the offender is a first-time offender with no prior criminal record, they can be sentenced to up to one year in prison. A DWI charge is serious, and this is why, to defeat the charge, you must have a powerful defense.

During your stay in the hospital for a DWI blood sample, your attorney can assist you in protecting yourself or a loved one. They can also make sure that the accident scene evidence is gathered. Keep in mind that the police will do everything they can to collect any evidence that might lead to a conviction.

What Impact Does a DWI Blood Sample Have on My Case in Texas?

Although Texas courts have determined that a DWI blood sample result is relevant to the question of intoxication, it is critical to remember that a DWI blood sample result does not prove that you were driving while intoxicated. Under Texas law, the prosecutor must prove that you were drunk when you operated your vehicle beyond reasonable doubt.

A blood sample result acquired hours after a DWI arrest can’t be utilized to determine whether you were intoxicated when you were detained. As a result, prosecutors will attempt to determine your alcohol level at the time you were driving using Retrograde Extrapolation.

Who Can Draw a Blood Specimen in a DWI Case?

A consented blood alcohol sample must be obtained in a sanitary location and only by a healthcare professional in Texas. To draw a blood sample, you’ll need a registered professional nurse, a qualified vocational nurse, or a licensed medical technician. A licensed medical technician may only acquire a sample of blood if the medical director for the organization that employs the technician-intermediate or technician-paramedic has provided their permission.

Common Errors with Texas DWI Blood Tests

When a person is charged with DWI as a result of a blood test, it is critical to have a criminal defense lawyer evaluate the blood sample processing to see whether the test was lawfully requested and handled appropriately. If there was any form of mistreatment of the blood sample, an attorney might submit a petition to suppress evidence that was obtained illegally or contest the veracity of the results.

Among the most typical issues with blood samples in DWI cases are, but are not limited to:

  • The alleged offender’s BAC has been influenced by the medicine they have taken.
  • Blood was not taken by authorized medical staff, and blood tests were not permitted by law.
  • Sample that has been contaminated
  • Failure to transfer alcohol concentrations in serum or plasma to alcohol concentrations in whole blood.

Can I Refuse the DWI Blood Test?

Yes. Despite coming under the concept of implied agreement, you have the right to decline any chemical test to detect your blood alcohol level under the Fourth Amendment. In recent years, several situations in Texas have occurred in which people have been forced or compelled to produce a sample to arresting officials. To be clear, law enforcement can only make a blood extraction under “exigent conditions,” which include the following:

  • You’ve been convicted of DWI before.
  • You were engaged in a car accident in which you or another person sustained injuries.
  • You were in a car accident that knocked you out or killed you.

Even in the most clear-cut cases, a forced blood examination might swiftly be called into doubt. If you were arrested for DWI and then given a blood test without your permission, contact an attorney right away; the evidence gathered may be suppressed and declared inadmissible.

What to do if you get a DWI in Texas?
