Who shall the Contractor inform if a member has provided a diluted sample?

The Medical Review Officer (MRO) is the correct party to be informed if a member has provided a diluted sample. The MRO is a licensed physician responsible for reviewing and interpreting laboratory results associated with drug testing. When a diluted sample is submitted, it raises questions about the validity of the test results. The MRO's role includes evaluating such scenarios and determining whether there are legitimate medical explanations for the diluted sample. This ensures that the testing process maintains integrity and fairness.

Other parties mentioned, while involved in different administrative or supportive roles, do not have the specialized training or responsibility to address the nuances of drug test results in the same way that the MRO does. The MRO acts as a crucial intermediary who can provide accurate assessments and recommendations based on their expertise in toxicology and medical evaluation, making them the appropriate contact in instances of diluted samples.
