(Example: you would need 1 order for major molds allergen screen, another order for dairy allergen screen, etc...)

Please contact the Lab if you need help to determine which allergen screen is appropriate or need to know what specific allergens are being tested in a particular allergen screen.

Mayo offers the following multiple allergen screens:
Geographical area panels for trees, grasses, and weeds.  Seasonal recommendations are provided by Mayo.Food panels include dairy, fish, grains, meats, nuts, seafood.
Other significant allergen groups including molds, household, epithelia groupings.

Specimen: 0.5 ml serum (enough for 1 multiple allergen screen) from a SST tube.
Processing:  
  • See Mayo catalog or Special Helps section of Lab Test Index for special instructions for specific Mayo ordering numbers for each allergen group. 
  • Mayo requests that each allergen screen is to have it's own Mayo number. 
  • Send a separate vial of serum for each allergen screen ordered. 
  • Send refrigerated to Mayo.
