Split (Bottle B) testing requests, timing windows, payment, who may request reconfirmation, and how reconfirmation failures are handled.

An employee requests a split specimen test after a verified positive result. The primary laboratory notifies the MRO that Bottle B was never received and was likely never collected. What is the MRO's next step?

A.Verify the result as a refusal to test because the employee failed to ensure a split was available.

B.Report the test as negative to the employer since the split specimen is unavailable.

C.Cancel the test and inform the DER that no further action is required for this donor.

D.Cancel the test and direct the DER to ensure an immediate collection under direct observation.
