If a blood sample was taken in your DWI case, your Fort Worth DWI attorney will likely collect the following information:

  • The methodology or procedure that was used by the lab.
  • A “split,” or portion of the sample that was taken.
  • Results of specificity or interference testing that was done to make sure that other compounds weren’t mistaken for ethanol.
  • The chain of custody of the sample that you provided.
  • Copies of bench notes that were taken during the analysis of your sample.
  • Records of internal tests that were performed regarding the analyst in the last year.
  • The checklist that was used by the phlebotomist who drew the blood.
  • Records of accuracy checks that were done on any vials that were bought from a manufacturer.
  • A copy of the run list, which lists the controls and samples that were tests as well as the order in which they were tested.
  • Results of controls that were used in the run, including solutions and blanks that were mixed in with the actual samples.
  • A review of the vial that contained your sample or a copy of the information that was printed on the vial.
  • The results of the sample that was taken from you.
  • Maintenance records of the device that was used for three months before and three months after your sample was taken.
  • Records of proficiency tests regarding the analyst and laboratory that were performed by an independent organization within the last year.
  • Chromatograms from the tests that were performed on your sample.

Your attorney will use this information to ensure that your samples were taken lawfully and that they were properly processed. If any issues are found, they may be used as grounds to have the charges dropped or to at least bolster your case.
