The Cottonwood Tree Allergy Test is a blood test that checks whether your immune system reacts to proteins from cottonwood tree pollen. It is usually ordered when someone has seasonal allergy symptoms such as sneezing, runny nose, or itchy eyes during the time cottonwood trees release pollen.

What it measures

  • Cottonwood pollen-specific IgE — The main marker; shows whether your blood contains antibodies that bind to cottonwood pollen.
  • Total IgE — A general measure of allergic antibody levels, sometimes included for context.
  • Other tree pollen IgEs — May be tested together to see if related trees also trigger a reaction.
  • Cross-reactive allergen markers — Help show whether symptoms could come from similar pollens rather than cottonwood alone.

Who it is for

A doctor or allergist typically orders this test for people with repeated seasonal symptoms that may line up with cottonwood pollen season. It can also help clarify which pollen is causing symptoms when several trees are in season at once.

Preparation

No fasting or special preparation is usually required. Tell your clinician about any allergy medicines you take, since some may affect test interpretation.

Results and what they mean

Results are reported as a level of specific IgE, often grouped as negative, low, moderate, or high. A clinician interprets the number alongside your symptoms and history, because a positive result alone does not confirm an allergy. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
