IgE Allergy Testing • 295 Allergens

IgE Allergy Blood Testing in Florida

If symptoms such as hives, swelling, wheezing, or vomiting occur after a particular food or environmental exposure, allergen-specific IgE testing may support a clinician's evaluation of possible allergy.

Our partner laboratory's allergE+ panel uses Nano-Bead Technology to measure allergen-specific IgE reactivity to 295 environmental and food allergens from 1 mL of serum. A positive result indicates sensitization; clinical allergy requires a compatible symptom and exposure history and is not established by the blood result alone.

Quick Answer

How Does the Allergy Test Work?

For $310, a single blood draw provides 1 mL of serum for our partner laboratory's allergE+ panel, which measures total IgE reactivity to 295 food and environmental allergens using Nano-Bead Technology. Antihistamines generally do not interfere with serum-specific IgE testing. The typical turnaround is 24 hours after the laboratory receives the sample.

Your report is complete on its own, and you can schedule a visit with Dr. Kiswani-Barley anytime for a personalized treatment plan.

Who Is IgE Allergy Testing For?

At Thrive Rx, IgE blood testing may be considered when a person's history suggests an immediate allergic reaction after a particular food or environmental exposure, when recurring allergy symptoms appear linked to specific exposures, or when skin testing is not practical. Testing should be guided by the clinical history rather than used as broad screening without a suspected trigger.

Recurring Allergy Symptoms

Itching, swelling, allergic rhinitis, allergic asthma, hives, skin rashes, vomiting, or other symptoms linked to possible exposures.

Possible Food or Environmental Triggers

People who want to investigate whether particular foods, pollens, molds, mites, animals, or other sources show IgE sensitization.

Reassessing a Known Allergy

People working with a clinician to help determine whether a known allergy should be reassessed. Blood results alone cannot confirm that an allergy has been outgrown.

Detectable allergen-specific IgE indicates sensitization, not necessarily clinical allergy. Clinical allergy requires symptoms that are compatible with exposure, and the IgE level or class does not reliably predict how severe a future reaction would be. Interpretation, avoidance decisions, and any challenge testing should be clinician-directed.

IgE Allergy vs. IgG Sensitivity: What's the Difference?

These tests measure different antibody responses and can contribute to a clinician-led root-cause evaluation. The clinical finding comes from integrating the laboratory result with symptoms, exposure timing, medical history, and any additional evaluation—not from either report alone.

Allergy Evaluation (IgE)

Measures IgE Sensitization

  • •Often evaluated when reactions occur soon after exposure
  • •IgE antibody mediated
  • •Can be life-threatening (anaphylaxis)
  • •Symptoms: hives, swelling, difficulty breathing
  • •Clinical history determines whether avoidance is needed
  • •A supervised challenge may be needed when the diagnosis remains uncertain

This test: allergE+ IgE Panel - $310

Food Sensitivity (IgG)

Measures Total IgG Reactivity

  • •Does not establish the timing or cause of symptoms
  • •Measures food-specific total IgG antibodies
  • •IgG can reflect dietary exposure or immune recognition
  • •Symptoms: bloating, fatigue, migraines, joint pain
  • •Monitor reactive foods and note symptoms
  • •Interpret with diet, symptoms, and medical history

See What Your Results Look Like

The laboratory report shows measured allergen-specific IgE reactivity to 295 allergens. Thrive Rx interprets those findings, when requested, alongside symptoms and exposure history.

Sample Allergy Test Report

Download a sample report to see the allergen-specific IgE levels reported for all 295 tested allergens, including laboratory classes from 0 to 4. These classes reflect measured antibody levels—not the severity of a clinical reaction.

  • Laboratory classes: Class 0 to Class 4 based on measured IgE level
  • Both extract-based and molecular allergen results
  • Cross-reactivity patterns identified
  • Results typically available within 24 hours

Common Allergy Symptoms

Allergies can affect multiple body systems. Do any of these sound familiar?

Respiratory

  • Sneezing
  • Runny Nose
  • Congestion
  • Wheezing
  • Asthma
  • Coughing

Skin

  • Hives
  • Eczema
  • Itching

  • Difficulty Breathing
  • Rapid Pulse
  • Dizziness
  • Anaphylaxis

When to Seek Emergency Care

If you experience throat tightening, difficulty breathing, rapid pulse, dizziness, or loss of consciousness after exposure to a potential allergen, seek emergency medical care immediately. These are signs of anaphylaxis, a life-threatening allergic reaction.

How Allergy Testing Works

From booking to results, we make allergy testing simple and convenient.

1

Order in the Thrive Rx Store

New and existing patients can order the test directly from the Thrive Rx store at the same price, without first booking an appointment. Existing patients may also request it through the patient portal, or Dr. Kiswani-Barley may recommend and order it through the EHR.

3

Complete the Blood Draw

A blood sample is collected and processed to provide the 1 mL of serum required for allergE+. Antihistamines generally do not interfere with serum-specific IgE testing.

4

Laboratory Analysis and Report

The laboratory measures IgE reactivity to 295 food and environmental allergens using Nano-Bead Technology. Typical turnaround is 24 hours after the sample is received.

5

Optional Physician Follow-Up

Direct purchasers receive a link to register in the secure patient portal. If you want further discussion or additional evaluation, you can book an appointment with Dr. Kiswani-Barley.
