Alpha-gal IgE blood test timing

An alpha-gal specific IgE blood test confirms the syndrome; test 4-8 weeks after bite or after a suspected reaction.

Steps

schema.org/HowTo
  1. 01
    Ask the clinician for a 'galactose-alpha-1,3-galactose specific IgE' blood test.
  2. 02
    Testing is most useful 4-8 weeks after a suspected sensitizing bite, since IgE takes time to rise.
  3. 03
    After a suspected reaction, also test the same panel to confirm.
  4. 04
    A positive test plus a compatible reaction history confirms alpha-gal syndrome.
  5. 05
    Levels can fall over time if further tick bites are avoided; many patients regain tolerance after 1-3 years tick-bite-free.
  6. 06
    Insurance often covers this test when ordered by an allergist with documented reactions.
