Longitudinal Alpha-gal IgE Levels in a University of Virginia Employee Cohort

The alpha-gal syndrome (AGS) is caused by IgE to galactose-α-1,3-galactose (α-Gal) and is strongly linked to tick bites. To date there have been limited studies on the natural history of AGS and α-Gal sensitization. Here we monitored α-Gal IgE levels over time among sensitized individuals in an employee vaccine cohort unselected for allergic disease.
