Common Questions

1. What are the benefits of having a blood test?
  • Unlike traditional skin-prick testing, a blood test can be performed irrespective of age, skin condition, medication, symptom and pregnancy.
  • A blood test requires only one blood sample
  • The test results will help you and your healthcare provider customize a treatment approach that’s right for you
  • Knowing your allergic triggers can help you take control and reduce your symptoms
  • Normal or negative results can help your healthcare provider rule out allergies in order to consider other possible triggers

2. How can a blood test help me know if I have allergies?

If you have allergies, your body produces an antibody called IgE that is specific to your allergic triggers. The blood test measures the amount of your IgE. Your healthcare provider can use your test results to identify the specific allergic triggers that may be contributing to your symptoms. Your specific IgE test results are as personal and unique as your fingerprint. After you receive your test results, you should review them with your healthcare provider and create a tailored plan to help reduce your exposure to your specific allergic triggers.


3. Does reducing exposure to my allergic triggers help?

Yes. Reducing exposure to one or more of your allergic triggers can help reduce your symptoms and your need for medication (4). This can only be accomplished by working with your healthcare provider to learn your unique allergy profile.


4. At what age can you start taking a blood test?

Adults and children of any age can take a blood test. For babies and very young children, a single needle stick for a blood sample is often more gentle than several skin tests.
