Any interfaced order for the 3rd generation HIV test will have the 4th generation HIV order added on to the patient and the 3rd generation order will be canceled with a cancel reason of “duplicate”. The results for these reflex orders will be delivered by paper, either by courier or fax based depending on the scenario. |
