Allergy Blood Test

What is an Allergy Blood Test?

An Allergy Blood Test is a type of test that measures the levels of antibodies in response to individual allergens. It can help reveal what triggers your allergy symptoms and help us choose the best treatment for you.

AZ Allergy Associates Allergy Blood Test

We on AZ allergy Associates only do the Immunoglobulin E (IgE) – specific immunoassay methods on testing blood for allergy.

This test includes:

  • Enzyme-linked Immunosorbent Assay (ELISA, or EIA) – is a test that detects and measures allergen-specific antibodies¬† in your blood.
  • Radioallergosorbent Test (RAST) – test your blood for specific IgE antibodies to find out what substances that you have allergic to.

What to expect from our service?

An AZ Allergy Associates certified health care provider will take a blood sample from a vein in your arm using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You maybe feel a little sting when the needle goes in or out. This usually takes three to five minutes.

Will I need to do anything to prepare for the test?
None. You don’t need any special preparations for the test.

At Arizona Allergy Associates, our team members know you may feel apprehensive about your blood test results and get them to you as quickly as possible. Depending on the specific test, it may take an hour or longer. Your doctor will explain the results and the need for further testing or follow-up.  Your treatment plan will depend on the type and severity of your allergy.

Dear Arizona Allergy Associates Community,

We want to reassure you that we are taking all precautions to prevent the transmission of viral illnesses, including COVID-19. As always, our exam rooms and instruments will be sanitized between each visit and our waiting rooms will be sanitized regularly throughout the day. We are asking that all persons entering the offices wear face coverings. Additionally, please limit the number of persons presenting to the office; we ask that only one parent attends with a child and that additional siblings remain home.

As an extra precaution, we will not be seeing any sick visits or patients with fever or flu-like symptoms at present. We request that any allergy injection patients and/or patients with upcoming office visits reschedule if they have been in contact with someone with fever or flu-like symptoms.

If you suspect you may have a viral illness such as influenza or COVID-19 you should seek emergency care services or primary care services as we are unable to swab and test for these illnesses.

Finally, for all allergy injections patients: out of an abundance of caution and in order to limit your exposure to any viral vectors, we request that you limit close contact in waiting areas. At this time we will temporarily allow you to sit in your vehicle during your 30-minute wait. You will still be required to come in and have your arm read at 30 minutes or earlier if you are experiencing any reaction during your wait. We may also alter your shot schedule to limit your visits to the clinic temporarily.

Thank you for your understanding during these difficult times. These changes are temporary and we will keep you posted with any changes or additional information.
