What are Test Results. Reporting test execution results is very important part of testing, whenever test execution cycle is complete, tester should make a complete test results report which includes the Test Pass/Fail status of the test cycle.
A non-negative result can also mean that a specimen was adulterated (tampered with), substituted or invalid. Positive drug test: A result that indicates that a specimen exceeded specified drug or metabolite cutoff levels. The result has undergone review and has been verified/confirmed by a medical review officer.his person reviews drug test results that are ânon-negative,â meaning results that are at or above the cutoff level and require additional review. It is the goal of the MRO to speak with the employee in question about the test result to see if he or she has an acceptable, approved reason for the result.
