This Code system is used in the following value sets:

  • ValueSet: AllergyIntoleranceCertainty (Statement about the degree of clinical certainty that a specific substance was the cause of the manifestation in a reaction event.)

Statement about the degree of clinical certainty that a specific substance was the cause of the manifestation in a reaction event.

This code system http://terminology.hl7.org/CodeSystem/reaction-event-certainty defines the following codes:

CodeDisplayDefinition
unlikely UnlikelyThere is a low level of clinical certainty that the reaction was caused by the identified substance.
likely LikelyThere is a high level of clinical certainty that the reaction was caused by the identified substance.
confirmed ConfirmedThere is a very high level of clinical certainty that the reaction was due to the identified substance, which may include clinical evidence by testing or rechallenge.
unknown UnknownThe clinical certainty that the reaction was caused by the identified substance is unknown. It is an explicit assertion that certainty is not known.
