A POCRG sends to the POCDM a message containing: its own ID, the care unit ID, the ordering provider ID, the operator ID, the patient/visit ID (or QC ID) and other information related to the test to start. The POCDM identifies the operator, and checks the patient identification. It then sends the answer back to the POCRG. The answer may be positive and carry the patient&aposs identity, or negative and carry the reject reason.
