Weed allergies are a type of seasonal allergic rhinitis triggered by pollen from weeds. They’re especially common in late summer and fall. Airborne weed pollen (like ragweed and pigweed) can travel miles and cause immune reactions. Avoidance is challenging due to the pollen’s widespread reach

How we diagnose weed allergies
At Sierra Allergy Asthma and Sinus Center, we use trusted diagnostic tools to pinpoint your weed allergens:

- Specific IgE blood tests: Ideal if skin testing isn’t suitable.
These methods help tailor a treatment plan just for you.
