Blood Testing
A blood test that identifies your child’s specific food and environmental allergies, helping us create a tailored treatment plan.
What is Allergy Blood Testing?
Allergy blood testing is a highly accurate method used to identify specific allergens that trigger allergic reactions. By measuring the levels of Immunoglobulin E (IgE) antibodies in your child’s blood, this test helps pinpoint the exact allergens causing symptoms, such as food allergies, environmental allergens, and insect stings.
Unlike skin prick tests, which involve exposing the skin to allergens, allergy blood testing is a non-invasive and safe alternative. This method is particularly valuable for children with sensitive skin or those who have had severe allergic reactions to skin testing. At Empower Allergy Treatment, we use the latest blood testing techniques to provide a comprehensive understanding of your child's allergy profile.
How Does Blood Testing Work?
Allergy blood testing is simple and straightforward. Here’s how the process works for you and your child:
- Initial Consultation:
- During the first visit, your allergist will conduct a thorough assessment of your child's symptoms, medical history, and lifestyle to determine which allergens to test for.
- Blood Sample Collection:
- A small blood sample is drawn from your child’s arm using a needle. The process takes just a few minutes, and the sample is then sent to a lab for analysis.
- Laboratory Analysis:
- In the lab, the blood is analyzed for specific IgE antibodies. These antibodies are produced by the immune system when exposed to allergens, and elevated levels indicate an allergy to that substance.
- Results and Diagnosis:
- Once the results are processed (usually within a few days), your allergist will review the findings and discuss the specific allergens that are triggering your child’s symptoms.
Key Benefits of Allergy Blood Testing
Allergy blood testing is an effective and reliable tool for diagnosing allergies, especially for children. Here’s why you may want to consider this method:
- Safe for Sensitive Skin:
Since blood tests don’t involve exposing your child’s skin to allergens, they are ideal for children with sensitive skin or those who have had adverse reactions to skin prick tests. - Accurate Results:
Blood tests provide highly accurate results, identifying your child’s exact allergens. This is particularly important when diagnosing food allergies such as peanuts, eggs, milk, or shellfish. - Minimal Risk:
Unlike skin tests, there’s no direct exposure to allergens, reducing the risk of triggering an allergic reaction. Blood tests are considered safer for children, especially those with severe allergies. - Comprehensive Allergy Profile:
Allergy blood testing can be used to assess a wide range of allergens, including food allergies, pollen, pet dander, and insect stings. This gives you a detailed view of what might be causing your child’s symptoms.
Who Should Consider Allergy Blood Testing?
Allergy blood testing is suitable for many children, particularly those with severe or complex allergies. It’s recommended for:
- Children with Severe Allergic Reactions:
If your child has experienced anaphylaxis or other severe allergic reactions to foods, environmental factors, or insect stings, blood testing is a safe way to identify the triggers. - Children Who Can’t Tolerate Skin Testing:
For children who find skin tests uncomfortable or have sensitive skin, blood testing is a non-invasive and stress-free alternative. - Children with Multiple Allergies:
If your child has multiple allergies or you are unsure which allergens are causing symptoms, blood testing provides a comprehensive allergy profile.
The Benefits of Blood Testing for Food Allergies
For children with food allergies, allergy blood testing offers several distinct advantages:
- Pinpoint Specific Food Triggers:
Blood tests help identify specific food allergies, such as to peanuts, eggs, milk, or shellfish. This is particularly important for children with multiple food sensitivities. - Long-Term Allergy Management:
Knowing which foods your child is allergic to helps you create an effective management plan, ensuring they can avoid their triggers and reduce the risk of allergic reactions. - Avoid Unnecessary Avoidance:
Blood testing provides accurate data, so you won’t have to guess or rely on trial and error. You can avoid unnecessary restrictions and make informed decisions about your child’s diet and lifestyle.
How Accurate is Allergy Blood Testing?
Blood testing for allergies is highly accurate but, like all medical tests, it’s not always 100% precise. False positives can occur, meaning the test might indicate an allergy even if one doesn’t exist. Similarly, false negatives may happen, where the test misses an allergy that’s present.
To get the most accurate interpretation, it’s essential to work closely with your allergist to review the results. The test results should always be considered in conjunction with your child’s medical history and symptoms.
Potential Risks and Side Effects
While allergy blood testing is generally safe, there are some potential risks to be aware of:
- Bruising or Discomfort at the Injection Site:
A common and temporary side effect, although it is usually mild. - Rare Allergic Reactions:
In rare cases, some children may have an allergic reaction to the materials used during the blood draw process, like antiseptics. This is usually mild and resolves quickly.
Conclusion
Allergy blood testing is an essential tool for diagnosing food allergies and environmental sensitivities in children. It offers a safe, accurate, and comprehensive way to identify allergens, which can help you manage your child’s allergies and avoid potentially life-threatening reactions.
If your child is suffering from unexplained allergic symptoms or has difficulty with skin tests, blood testing may provide the clarity you need. Empower Allergy Treatment can help you navigate this process and create a personalized plan to manage your child’s allergies effectively.

Frequently Asked Questions
Find answers to common questions about allergy care and treatments.
Food allergies occur when the immune system mistakenly reacts to proteins in certain foods. These reactions can range from mild symptoms like hives to severe conditions like anaphylaxis. Treatment involves avoiding allergenic foods, using medications to manage reactions, and in some cases, oral immunotherapy to desensitize the immune system. An allergist can help develop a personalized treatment plan for your child. Learn more about our services here.
If your child shows symptoms like hives, stomach issues, or difficulty breathing after eating, you should consult an allergist. Early diagnosis can prevent severe reactions and guide treatment. If you’re unsure whether a food allergy is causing symptoms, an allergist can provide clarity through testing. It's also important if there’s a family history of food allergies.
If your child experiences symptoms like swelling, stomach pain, or breathing issues after eating certain foods, testing can help identify the cause. Testing is also recommended if there’s a family history of allergies or if you're unsure about which foods might be triggers. An allergist can assess whether food allergy testing is necessary based on symptoms and medical history. Contact us today to schedule your consultation.
Yes, food allergies can be managed and, in some cases, treated. Treatments like oral immunotherapy (OIT) can gradually desensitize the immune system to food allergens, reducing the risk of severe reactions.
