What action is taken if a test result is questionable due to external factors?

When a test result is questionable due to external factors, it is critical to ensure the accuracy and reliability of the results. Retaking the test under controlled conditions allows for mitigating any influences that could compromise the integrity of the initial test. By conducting the re-test in a more controlled environment, it reduces the possibility of external variables skewing the results, leading to a more valid and dependable outcome.

Ensuring that the testing conditions are optimal is essential for maintaining the standardization of the testing process, which is particularly important for evidentiary purposes. This approach reflects adherence to protocols designed to uphold the integrity of the testing process and reinforces confidence in the resulting data that may be presented in legal contexts.
