Get the Facts About Chemical Tests

To stand up in court chemical tests must be administered consistently and correctly. Your Orange County DUI lawyer knows all the technical details of how they work and may pursue the facts through an investigation or discovery process. Be aware of these concepts in chemical testing as your case proceeds:

Blood and urine analysis factors

  • Chain of custody of the test sample(s)
  • In a blood test, the phlebotomist’s checklist; or instructions used by the person obtaining the urine sample
  • The analyst’s skill as measured by proficiency tests
  • Notes taken by the laboratory analyst (bench notes)
  • Licensing or testing of the laboratory
  • Analysis methods or procedures used by the lab
  • Vials used in testing: The manufacturer’s quality checks
  • Information affixed to the vial
  • Quality and purity of controls used in the run. These solutions are mixed in with your sample.
  • Your test sample’s chromatogram (a visual metric of test results)
  • Specificity/interference testing (ensuring that other compounds such as ethanol were not analyzed by mistake)
  • Availability of a “split” sample for independent testing
  • A printout of samples run on the same equipment before and after yours for comparison
  • Maintenance and calibration records for the testing equipment
