How to use this site

The objective of Extractopedia is to assist you in understanding allergenic extracts and how they are commonly used for both skin testing and in the preparation of treatment vials for subcutaneous immunotherapy (SCIT).

To those who have prior experience with allergenic extracts, many of the elements on this site may seem to be review. However, we have found that the handling of allergenic extracts and the procedures for mixing treatment vials can differ considerably from practice to practice.

Additionally, allergy training programs in North America have adopted various protocols and procedures for handling and mixing extracts. Given the reality of these differences in training, every effort should be made to promote consistency in the allergy practice.

This site frequently references published, clinical guidelines, which have been compiled by allergy and immunology working groups across allergy specialties.

Some sections within this site may refer to supplemental documents or information available from the website host or through outside organizations.

Practice Support

Please feel free to encourage others in your practice to explore the information on this website. In particular, anyone in your practice who handles allergenic extracts in any way (e.g. ordering, storing, and/or mixing) should become familiar with certain sections. It may also be helpful to refer to this certain sections when developing training programs for your staff or specific policies and procedures for your medical practice.
