A cashew allergy test checks your blood for antibodies that may indicate an allergy to cashew. It is usually ordered when you have had symptoms after eating cashew, or when a clinician needs to confirm or rule out a cashew allergy.

What it measures

  • Cashew-specific IgE — An antibody that can be elevated in people allergic to cashew.
  • Total IgE — A general allergy antibody level that can help interpret your results.
  • Other tree nut-specific IgE — Tests for related nuts such as walnut or pecan, often done at the same time.

Who it is for

This test is typically ordered by an allergist, primary care clinician, or pediatrician when a person reports reactions after eating cashew or has other signs of a possible nut allergy.

Preparation

No fasting or special preparation is needed for this blood test. You can eat and drink normally before your appointment.

Results and what they mean

Results are reported as a number or class for each antibody tested. A clinician interprets these results along with your symptoms and history; a positive test alone does not always mean you have an allergy. This is general information, not medical advice.

Do I need to avoid cashew before the test?

No. You do not need to avoid cashew before this blood test. In fact, avoiding it is not required for the test to work.

How long does it take to get results?

Results are usually available within 1 to 3 business days after your blood sample is collected.
