What Is the Allergy Test Combo (IgE + IgG)?

Allergic and intolerance-related reactions do not always occur in the same way.

This combo package integrates two widely used testing approaches:

• IgE Allergy Testing – evaluates immediate-type allergic reactions

• IgG Food Intolerance Testing – analyzes delayed food-related reactions

With one blood draw, both assessments can be completed at the same time, helping to reduce the risk of missing potential contributing factors by relying on a single test alone.

What Is the Difference Between IgE and IgG?

Allergic or intolerance-related reactions may occur through different immune mechanisms, and not all reactions appear immediately.

IgE and IgG are two different types of antibodies, each reflecting a different type of reaction risk:

IgE (Immediate-Type Allergic Reactions)

• Reactions usually occur shortly after exposure or consumption

• Common symptoms may include:

  • Allergic rhinitis (runny or blocked nose)

  • Sneezing

  • Skin itching or hives

  • Eye irritation or redness

  • Asthma or breathing discomfort

IgG (Delayed Food-Related Reactions)

• Reactions may appear several hours or even days after food consumption

• Symptoms are often less obvious and may include:

  • Digestive discomfort or bloating

  • Recurrent skin issues

  • Persistent fatigue or discomfort

As immediate and delayed reactions involve different immune pathways, relying on a single test may not provide a complete picture.
This Allergy Test Combo (IgE + IgG) allows a more comprehensive assessment from both perspectives.

Who Is This Package Suitable For?

This Allergy Test Combo (IgE + IgG) is suitable for individuals who wish to obtain a more complete assessment of allergy- and food-related reaction risks, including those who:

• Suspect both immediate allergic reactions and delayed food-related responses

• Experience recurring allergy symptoms without a clear cause

• Have symptoms such as allergic rhinitis, skin itching, hives, or breathing discomfort

• Suffer from long-term digestive discomfort, bloating, or recurrent skin issues

• Have previously undergone a single allergy or food test without clear findings

• Prefer one blood draw to complete a more comprehensive analysis

• Are concerned about their own or their child’s allergy-related conditions

Test Items Included

This Allergy Test Combo (IgE + IgG) combines two assessments in a single blood draw:

🔬Comprehensive Allergy IgE Test

The IgE allergy test evaluates the risk of immediate-type allergic reactions, covering a range of commonly encountered allergens, including:

• Selected food allergens

• Selected environmental allergens

This test helps identify substances that may be associated with rapid-onset allergic symptoms.

🧪 IgG Food Intolerance Test

The IgG food intolerance test analyzes IgG antibodies related to delayed food-related reactions, covering multiple commonly consumed food items.

These reactions may not be immediately noticeable and can develop gradually over time.

Only Need a Single Test?

If you wish to focus on one specific type of reaction, individual testing options are also available:

🔹 Comprehensive IgE Allergy Test

Designed to assess immediate-type allergic reactions, suitable for individuals experiencing:

• Allergic rhinitis or sneezing

• Skin itching or hives

• Eye irritation or redness

• Asthma or breathing discomfort

🔹 Food Intolerance IgG Test

Designed to analyze delayed food-related reactions, suitable for individuals experiencing:

• Long-term digestive discomfort or bloating

• Recurrent skin issues

• Discomfort after meals with unclear causes

For individuals seeking a more comprehensive assessment while avoiding repeated blood draws, the Allergy Test Combo (IgE + IgG) may be a more cost-effective option.

Frequently Asked Questions (FAQ)

Q1: What tests are included in the Allergy Test Combo?

This package includes IgE comprehensive allergy testing and IgG food intolerance testing, completed with a single blood draw.

Q2: What is the difference between IgE and IgG?

IgE reflects immediate-type allergic reactions, while IgG is associated with delayed food-related reactions. Each provides insight into different immune response mechanisms.

Q3: Do I need to fast before the test?

No fasting is required. You may eat and drink normally before the blood test.

Q4: Is this test suitable for children?

This package is suitable for children aged 5 or above as well as adults. Children should be accompanied by a parent or guardian.

Q5: Can the results be used for medical diagnosis?

This test provides a risk assessment and should be interpreted alongside clinical symptoms. It does not replace a medical diagnosis.
