A case of alpha-gal syndrome: Recall urticaria and 10 years of measurements of IgE to galactose-α-1,3-galactose

Abstract

Alpha-gal IgE level can change rapidly. Reassessment of a patient’s alpha-gal IgE level may be helpful in the patient’s clinical follow-up. Pruritus related to the site of a previous tick bite strengthens the diagnosis of alpha-gal syndrome.
