What does a "non-negative" test result indicate?

• A. A result showing no substances present
• B. A test requiring additional confirmation for validity
• C. A positive result with no further action required
• D. A result that can be immediately accepted

Answer: (B)

A "non-negative" test result indicates that a screening has detected the presence of at least one substance, but it does not confirm whether that result is positive or negative in terms of legality or further action. This classification of a test result means that additional confirmation through more specific testing is often necessary to validate the findings. Thus, while a non-negative result suggests that potential substances may have been encountered, it is not definitive—prompting the need for further analysis to clarify the nature of the result. Additional confirmation tests are typically necessary to ensure the accuracy and reliability of the result before any decisions or actions are taken.
