# The Injection Object

> Documents an injection administered to a patient.

Documents an injection administered to a patient. It may be an injection given by the practice and documented immediately (`is_new=true`), or a "historical" injection, given to the patient elsewhere, that the practice documented after the fact (`is_new=false`).

`practice` identifies the [practice](/articles/rest/practice-api/practices/the-practice-object) that documented the injection.

`patient` identifies the [patient](/articles/rest/patient-profile-api/patients/the-patient-object) that was given the injection.

`reference_medication_id` identifies the [reference medication](/articles/rest/reference-data-api/reference-medication-beta/the-reference-medication-object) administered in the injection.

`packaged_medication_id` identifies the [packaged medication](/articles/rest/reference-data-api/packaged-medication-beta/the-packaged-medication-object), i.e. the specific packaging of the reference medication, administered in the injection. This is `null` if the injection package's NDC wasn't found in Elation's standard formulary when the injection was documented.

`ndc` is the NDC of the injection package. This is the `ndc` of the associated [packaged medication](/articles/rest/reference-data-api/packaged-medication-beta/the-packaged-medication-object) if the injection package's NDC was found in Elation's standard formulary when the injection was documented. Otherwise, `packaged_medication_id` is `null` and `ndc` is the value entered by the user who documented the injection.

`service_location_id` identifies the [service location](/articles/rest/practice-api/service-locations/the-service-location-object) where the injection was given.
