Request for feedback from the SNOMED CT Allergy Clinical Reference Group (CRG) on: Animal dander allergies

Summary
There are several concepts in SNOMED CT of the type Allergy to animal x dander (finding) but none of just Allergy to animal x (finding). Animal dander is not an allergen but rather a structure on which allergenic proteins may adhere. Allergy to animal x dander concepts are not clinically useful as avoidance would be focused on the animal itself rather than a part of the animal and most would not recognize a specific source from which the actual allergen is derived. In addition, the same allergenic protein may be found in several different sources.

The CRG would like to consider a request to inactivate Allergy to animal x dander (finding) concepts and replace with new Animal protein x (substance) and Allergy to animal x (finding concepts) with the following model:

• FSN=Allergy to animal x protein (finding)
• PT=Allergy to animal x

=== 420134006 |Propensity to adverse reaction (finding)|: { 719722006 |Has realization (attribute)| = 472964009 |Allergic process (qualifier value)|, 246075003 |Causative agent (attribute)| = |Animal protein x (substance)| }

Please review this request and provide your responses in this Forum by Monday 16th November. Thank you!
