Allergy testing checks your blood for specific antibodies that your immune system makes in response to allergens like pollen, pet dander, or certain foods. It is ordered when you have symptoms such as hives, sneezing, or digestive issues that may be triggered by an allergy.

What it measures

  • Total IgE — Overall level of allergy-related antibodies in your blood.
  • Specific IgE — Antibodies that target a particular allergen, such as peanut or dust mite.
  • Allergen panels — Groups of common allergens tested together, like grasses, trees, or molds.
  • Component tests — Detailed markers that can help show how likely a reaction is to a specific allergen.

Who it is for

A primary care doctor or an allergist typically orders this test after reviewing your symptoms and medical history.

Preparation

No fasting is required. You can eat and drink normally before the blood draw, and you do not need to stop most medications unless your doctor tells you to.

Results and what they mean

Results are reported as a number for each allergen tested, often with a reference range. Higher numbers may suggest sensitivity, but only a clinician can interpret them with your symptoms. This is general information, not medical advice.

Most results are ready in 1 to 3 business days.

Can I take allergy medicine before the test?

Yes, most allergy medicines do not affect blood test results, but check with your doctor first.

What if my results are positive?

A positive result means you may be sensitive, but it does not always mean you have an allergy. Your doctor will explain what it means for you.
