Allergy Tests

One in three adults in the US has an allergy. If you frequently struggle with sneezing, itching, or bloating, an allergy blood test is a reliable way to uncover your triggers. Our comprehensive allergy blood test panels are designed to provide clear insights into your sensitivities and give you a path toward relief.

An allergy blood test not only helps ease symptoms but also prevents severe complications like anaphylactic shock. While allergy symptoms often look similar, allergens vary widely. Our allergen profiles are categorized by triggers, making it easier for your healthcare provider to establish a proper diagnosis and recommend treatment.

What are Allergies?

Allergies occur when the immune system overreacts to substances called allergens. During exposure, the body produces antibodies such as immunoglobulin E (IgE), which trigger the release of histamine and other chemicals that cause symptoms. Common allergens include:

• Environmental: Dust mites, pet dander, pollen, mold

• Food: Milk, eggs, peanuts, shellfish, wheat

• Medications: Penicillin, aspirin, chemotherapy drugs

• Insect stings: Bees, wasps, hornets

The widespread occurrence of allergies has rapidly increased in recent decades. Allergies are now the 6th leading cause of chronic illness in the US, with annual costs exceeding $18 billion. Common allergic conditions include:

• Hay fever – Affects up to 10% of adults and 40% of children

• Asthma – Affects over 25 million Americans

• Eczema – Affects over 30 million Americans

• Food allergies – Affect over 32 million Americans

• Anaphylaxis – Causes 500–1,000 deaths annually

What Is The Role of Allergy Testing

An allergy blood test identifies the exact source of your reactions, whether from environmental allergens like dust and pollen, or from foods, medications, and chemicals. By pinpointing your triggers, you gain control over your health with tailored strategies to avoid or treat them effectively.

What Are The Types of Allergy Blood Tests

We offer a comprehensive line of blood work allergy tests based on various types of allergens. These include:

• Food allergy testing can pinpoint common possible allergens, including milk, grains, shellfish, meat, fruit, nuts, vegetables, and fish. 
• Environmental allergy tests cover seasonal allergies caused by pollens, dust, and molds. These also include cat hair, grass, dog dander, and fire ants.
• State-specific allergy tests include tests for common allergens found in different states. For example, if you live in Kansas, check out the Allergen Profile for KS, ND, NE, SD Blood Test.

Who Should Get Tested for Allergies?

Anyone experiencing recurring allergy symptoms should consider an allergy blood test. Those with a family history of allergies or who already live with allergic conditions can benefit from identifying additional triggers.

Symptoms that may indicate the need for an allergy blood test include:

• Skin redness, swelling, rashes, or hives

• Runny nose or sneezing

• Stomach pain or bloating

• Vomiting or diarrhea

• Coughing or difficulty breathing

With over 100 million Americans experiencing allergies each year, an allergy blood test is more important than ever for accurate detection and management.

When To Do Allergy Testing

It’s best to schedule an allergy blood test as soon as you notice symptoms. Untreated allergies can worsen and lead to serious consequences. Anaphylaxis, in particular, requires immediate diagnosis and intervention. Having access to an allergy blood test near you ensures quick detection, safer treatment, and prevention of severe complications.

Understanding Allergy Test Results

Interpreting test results is essential for proper treatment. Allergists evaluate:

IgE antibody levels in kU/L units – Values above 0.35 kU/L typically indicate an allergy. Higher levels often correlate with more severe reactions.

Severity classification (Grades 1–6):

• Grades 1–2: Mild, usually managed by avoidance

• Grades 3–4: Moderate, often requiring medication

• Grades 5–6: Severe, requiring emergency treatment

Combined with your clinical history, these results guide the best treatment options.

Frequently Asked Questions

How long does it take to get allergy blood test results?
Most results are available within a few days, though turnaround can vary depending on the lab. Once processed, your provider can review the findings and discuss next steps.

Is fasting required before an allergy blood test?
Fasting is not typically required. However, some healthcare providers may recommend avoiding certain medications beforehand, so always confirm any special instructions prior to testing.

Can children take an allergy blood test?
Yes, allergy blood tests are safe for children. They can be especially useful for younger patients who may not tolerate skin-prick testing.

How does an allergy blood test differ from a skin test?
While skin tests measure reactions on the surface of the skin, blood tests analyze the presence and concentration of IgE antibodies in the bloodstream. Blood testing is often preferred when skin conditions or medications interfere with skin-prick results.

Are allergy blood tests covered by insurance?
Coverage varies by insurance provider and plan. Many policies cover allergy testing when medically necessary, but it is best to confirm coverage before scheduling.

What should I do after receiving my allergy blood test results?
After results are reviewed, your provider may recommend lifestyle adjustments, avoidance strategies, or medical treatments such as antihistamines or immunotherapy. Following up with a healthcare professional ensures you take the right steps for long-term management.
