Can A Toxicologist Challenge The Accuracy Of A Breath Test Or Blood Result In A DWI Case?

Absolutely. In some cases, the government needs to present the testimony of a toxicologist to make the blood or breath test admissible. However, during cross-examination, the toxicologist can be challenged regarding the conduct of the test and whether proper procedures were followed. Mistakes in the test itself, as well as errors in interpretation and how the test relates to the concentration at the time of driving, can be subjects of the examination. 

Additionally, independent toxicologists can be called to testify for the defense, highlighting potential flaws in the test’s conduction and arguing for its inadmissibility. Their testimony can question the reliability of the results and challenge the notion that the person was intoxicated at the time of driving.
