Allergy tests are available for many plant species. Check the research page to determine what species grow in your local area. Your Allergy Forecast will list the predominant pollens that are causing your local allergy conditions. These pollens change over the course of the year. They are often flowering trees and plants in spring, and grasses and weeds in the summer and fall. Check your local forecast when you notice your allergies flaring up. You can also record your condition on your Allergy Diary to keep track of the predominant pollens that may be causing your allergies. This might help inform you for which species to test for.
