Can skipping any steps in the urinalysis process invalidate the test?

Skipping any steps in the urinalysis process can indeed invalidate the test. The urinalysis procedure is designed with a series of critical steps to ensure both the accuracy of the test results and the integrity of the testing process. Each step plays a vital role, from the collection and handling of the urine sample to the testing and reporting of the results.

If any steps are overlooked or improperly executed, it can compromise the chain of custody, introduce contaminants, or lead to procedural errors. This could result in false positives or negatives, ultimately undermining the purpose of the urinalysis, which is to detect substance abuse and ensure compliance with military regulations. Maintaining strict adherence to all steps in the process is essential for ensuring the reliability and validity of test outcomes.
