allergen
Let an agent explain allergens and their kinds, relay mechanisms, common allergens, labelling and testing from allergy and regulatory sources in general terms, route people with reactions to emergency and medical care, and distinguish allergens from irritants, toxins and pathogens.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain allergens and their kinds, relay mechanisms, common allergens, labelling and testing from allergy and regulatory sources in general terms, route people with reactions to emergency and medical care, and distinguish allergens from irritants, toxins and pathogens.
A substance that provokes an allergic immune response in sensitised people, including allergenic proteins from pollen, dust mites, animal dander, foods and venoms, plant antigens, and chemical contact allergens used in cosmetics and industry such as the preservatives methylchloroisothiazolinone, methyldibromo glutaronitrile and bronopol and the rubber accelerator dithiobisbenzothiazole; allergens are regulated in food labelling and cosmetics, and reactions range from mild to anaphylaxis, which is an emergency.
What it is for: Not applicable; a class of disease-causing agents.
It can be route emergencies first; explain kinds and mechanisms; relay labelling and testing; distinguish related agents.
Distinguishing features
Immune sensitisation
Proteins and chemicals
Regulated labelling
Range of severity
What it looks like
Not a visible object; proteins and chemicals.
Physical character
major food allergens, EU: 14 count - labelling list
people with allergies worldwide: hundreds of millions count - estimates
IgE: antibody in immediate allergy note
How it is recognised
Substance provoking an allergic response
Pollen, dust mite, food and venom allergens; contact allergens such as isothiazolinones, bronopol and rubber chemicals
Irritants damage without immune sensitisation; toxins poison; pathogens infect

What the second pass must settle

- How should allergy and regulatory sources be linked?
- The registry entry has merged aliases naming specific preservatives and chemicals; should they be split off?
