How many times is each urinalysis sample tested by Navy drug screening laboratories?

The urinalysis samples collected for drug screening in the Navy are tested three times to ensure accuracy and reliability of the results. This process typically involves an initial screening test, followed by a confirmation test if the initial result is positive. The third test serves as a quality assurance measure to minimize the chance of false positives, ensuring that the findings are valid and trustworthy. By testing three times, the laboratories enhance the integrity and credibility of the drug screening process, providing a thorough and precise evaluation of each sample. This multi-testing method is crucial in maintaining the Navy's standard for maintaining a drug-free environment and upholding the overall readiness and effectiveness of its personnel.
