drug testing expert witness services

What is a drug testing expert witness?

A drug testing expert witness provides independent, scientifically grounded analysis of drug and alcohol test results and procedures, helping attorneys, courts, and organizations understand the complexities of testing. They review how samples were collected, handled, and analyzed, evaluate laboratory methods and accuracy, interpret results, and identify potential errors or inconsistencies. By translating testing data, procedures and policies into clear, defensible opinions, a drug testing expert witness supports legal strategy through expert reports, depositions, and courtroom testimony.
