If a player provides a negative dilute specimen during pre-employment testing, what designation is given?

When a player provides a negative dilute specimen during pre-employment testing, the designation typically given is “Stage One - by Test.” This classification indicates that the test results may have been affected by the specimen being dilute and that further examination or action is often warranted. A negative dilute can occur when a player has consumed a significant amount of liquid, which can lead the sample to contain lower concentrations of substances that are typically tested for, such as drugs.

This response is important in the context of the NFL's substance abuse policy, as it acknowledges that while the specimen is technically negative, the dilute nature raises flags that may require re-testing. On the other hand, the designations of "Stage Two - by Behavior" and "No designation given" would not apply in the context of a negative dilute, as these pertain to different circumstances or behaviors within the policies of substance testing.
