There is no difference in terms of understanding the meaning.

However, the words "allergen" and "allergens" do not appear in textbooks.

Instead of "allergens" and "sensitizers".

So, personally:

The most correct term is "allergen".

It's more correct to say "allergens".

It can also be "allergenic" if you put it together.

Hello, first of all thanks for the invitation!

allergic reaction

There are four types of hypersensitivity reactions in immunology, each with a different mechanism. The allergic reaction that we talk about in our daily life is called Type I hypersensitivity reaction in immunology, which has great individual differences and genetic correlation, and it occurs and subsides quickly, and there is often no damage to tissues and organs but only disorders of physiological functions.

allergens

The word "source" in allergen means the beginning, origin, root, and the source, and allergen means where the source of the allergic reaction is or what the cause is.

allergens

Allergens should refer to a substance (antigen) capable of inducing an allergic reaction, but only specific substances, such as certain drugs (penicillin, sulfonamides, procaine, etc.), such as certain inhalants (pollen, dust mite excretions, etc.), such as certain foods (milk, eggs, etc.).

both sides)

To summarize, one refers to the cause, the source, and the other refers to the specific substance. For example, if a person has allergic rhinitis triggered by contact with pollen on a field trip, the allergen is pollen, which means that the substance causing the allergy is pollen.

(*^__^*) ...... I don't know if it's clear what the relationship between the two terms is, but it's often used interchangeably in everyday life, and there's no intentional distinction made.

I hope that my answer is helpful to you!
