Step-by-step explanation:
The function of an EHR that allows for electronic test ordering and receipt of results is the 4) ancillary order integration.
Ancillary order integration in an EHR system allows healthcare providers to electronically order laboratory tests, imaging studies, or other ancillary services for their patients.
The results of these tests are then electronically received and integrated back into the patient's electronic health record, making it easily accessible for future reference.
This feature streamlines the process of ordering and receiving test results, eliminating the need for manual paperwork and reducing the chances of errors or delays.
