Allergy blood testing measures the amount of allergen-specific IgE antibodies in your bloodstream. When you have an allergic reaction, your immune system produces IgE in response to what it sees as a threat—whether it’s pollen, pet dander, peanuts, or something else. By analyzing this response, we can pinpoint what may be triggering your symptoms.
At Modena Health, we use blood testing as part of a complete allergy workup, often alongside a full history and physical exam. For many patients, especially those who can’t stop antihistamines or have certain skin conditions, blood testing offers a safe and reliable alternative to skin testing.
The process is simple. After reviewing your symptoms and medical history, one of our providers will order a blood panel that screens for common allergens based on your lifestyle and exposures. A quick blood draw is performed, and the sample is sent to a certified lab. There’s no need to stop medications like antihistamines, and there’s no skin irritation involved.
Once your results are back (typically within a week) we’ll meet with you to explain what the numbers mean and how they relate to your symptoms. This helps us create a treatment plan that’s targeted, not trial-and-error.
Blood testing can help evaluate symptoms related to:
Allergy blood testing offers clarity without physical discomfort. With one simple draw, you get information that can shape your care for years to come. It’s often the right choice for patients who:
Most patients experiencing chronic allergy symptoms (especially those who can’t undergo skin testing) are good candidates for blood testing. It’s safe for children, older adults, and those with skin sensitivities or complex medical histories. If you’re currently taking antihistamines, steroids, or biologic medications that interfere with skin test accuracy, this may be the preferred diagnostic route.
During your initial consultation, your Modena Health provider will determine whether blood testing is the best first step based on your symptoms and medical background.
There’s no recovery needed after allergy blood testing. You may have minor soreness or bruising at the site of the blood draw, but most patients return to work, school, or regular activities immediately. Your provider will contact you when your results are ready, and a follow-up appointment will be scheduled to discuss next steps.
Allergy blood test results typically return within 5 to 7 business days. You’ll receive a breakdown of your IgE levels for each allergen tested—along with a detailed interpretation from your provider. These results help guide next steps, such as avoidance strategies, medications, or allergy immunotherapy.
Our goal is to help you stop guessing and start addressing your symptoms with confidence.

We use blood testing as one part of a broader, evidence-based approach—always customized to your symptoms, health history, and goals.

The test involves a quick blood draw, similar to routine lab work. Most patients experience only brief discomfort.
Results are typically available within 5 to 7 business days. Your provider will review them with you during a follow-up visit or phone consultation.
Panels can be tailored to include environmental allergens like pollen, pet dander, and dust mites, or food allergens such as milk, eggs, peanuts, and shellfish.
No. Antihistamines, steroids, and most allergy medications do not interfere with blood testing, which makes it ideal for patients currently taking those treatments.
Not necessarily—it depends on your medical situation. Blood testing is preferred when skin testing isn’t safe or reliable due to medications or skin conditions.
Yes. Blood testing is often used for infants and young children who are too young for skin testing or have sensitive skin.
Blood tests are highly accurate when interpreted in the context of your full medical history. They measure immune system activity, not just exposure.
