False Ragweed (w4) IgE details

What False Ragweed (w4) IgE shows

False ragweed is a plant related to true ragweed that also releases allergenic pollen in the fall. This test measures IgE antibodies specific to false ragweed pollen to check for allergic sensitization, contributing to fall seasonal allergy symptoms. Because it's closely related to common ragweed and shares similar pollen proteins, people sensitized to one are often sensitized to both, and it's typically included as part of a regional weed allergen panel.
