Dosing of allergen extracts is in bioequivalent allergy units (BAU), weight per volume (w/v), or protein nitrogen units (PNU), but "major allergen content" may be a more standardized and reliable method of dosing and for characterizing allergen extracts; however, not all allergens have been standardized.

Extracts with modifications that decrease allergenicity (adverse reactions) without reducing immunogenicity (effectiveness) are under investigation.
