  • Total IgE (if included) — reflects overall allergic antibody level, though it is not specific to this plant
  • Other weed pollen IgE (if panel) — shows sensitization to related weeds that may cause similar symptoms

A healthcare professional collects a small blood sample from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered
