What is the 2-in-1 Allergy Check (IgE + IgG)?

Allergies or bodily discomfort reactions do not come in a single form, nor do they always appear immediately.

The 2-in-1 Allergy Check (IgE + IgG) combines two common blood testing methods to evaluate different types of reaction risks simultaneously with a single blood draw:

• IgE Allergen Test:Primarily evaluates immediate allergic reactions.

• IgG Food Intolerance Test：Primarily analyzes IgG antibodies associated with delayed food reactions.

Because the immune mechanisms behind immediate allergic reactions and delayed food reactions are different, undergoing only a single test may not provide a complete understanding of all contributing factors.

This 2-in-1 package allows both tests to be completed from a single blood sample, providing a more comprehensive reference while avoiding repeated blood draws.

What is the Difference Between IgE and IgG?

Allergic or adverse reactions can be categorized into different types, and not all reactions occur immediately.

IgE and IgG are two different immune antibodies, each reflecting different forms of reaction risks:

IgE (Immediate Allergic Reaction)

• Typically occurs within a short period after contact or ingestion.

• Common symptoms include nasal allergies, runny nose, sneezing, skin itchiness, hives, wheezing, or respiratory discomfort.

IgG (Delayed Food Response)

• Reactions may appear hours or even days later.

• Symptoms are more subtle and are often associated with gastrointestinal discomfort, bloating, recurrent skin issues, or fatigue.

Since the mechanisms of immediate and delayed reactions differ, testing for only one type may not offer a complete overview of underlying factors.
This “2-in-1 Allergy Check Package (IgE + IgG)” combines both tests to help analyze different reaction risks more comprehensively.

Who is This Package Suitable For?

This “2-in-1 Allergy Check Package (IgE + IgG)” is ideal for individuals who want a single, comprehensive evaluation of different types of allergies and discomfort reactions, particularly those who:

• Suspect they experience both immediate allergic reactions and delayed food reactions

• Suffer from recurring allergic or discomfort symptoms with unknown causes

• Experience nasal allergies, runny nose, sneezing, skin itchiness, hives, or wheezing

• Are chronically troubled by gastrointestinal discomfort, bloating, recurrent skin issues, or fatigue

• Have taken a single allergy or food test before but still lack a complete understanding of their triggers

• Prefer to complete a full analysis with a single blood draw to avoid repeated blood sampling

• Are concerned about their own or their children’s allergy conditions and want comprehensive reference data

Combining the Comprehensive Allergen Panel IgE Test and Food Intolerance IgG Test , this package helps analyze potential reaction risks from multiple angles, making it suitable for those seeking a more thorough assessment.

Prefer a Single Test Only?

If you prefer to focus your evaluation on a specific type of allergy or discomfort reaction, you can also opt for individual test services:

This test primarily evaluates risks associated with immediate allergic reactions. It is suitable for individuals experiencing:

• Nasal allergies, runny nose, sneezing

• Skin itchiness, hives

• Itchy or red/swollen eyes

• Wheezing or respiratory discomfort

🔹 Food Intolerance IgG Test

This test primarily analyzes IgG antibodies linked to delayed food reactions. It is suitable for individuals experiencing:

• Chronic gastrointestinal discomfort, bloating

• Recurrent skin issues

• Discomfort after eating with unknown causes

• Suspected adverse reactions related to daily diet

If you wish to fully evaluate both immediate allergies and delayed reactions at once while avoiding repeated blood draws, this “2-in-1 Allergy Check Package (IgE + IgG)” provides a more comprehensive and cost-effective option.

Frequently Asked Questions (FAQ)

Q1: What tests are included in the 2-in-1 Allergy Check Package?

This package combines the Comprehensive IgE Allergen Test and the IgG Food Intolerance Test. With just a single blood draw, it simultaneously assesses the risks of both immediate allergic reactions and delayed food reactions.

Q2: What is the difference between IgE and IgG?

IgE primarily reflects immediate allergic reactions, where symptoms usually appear shortly after exposure or ingestion.

IgG relates to delayed food reactions, where symptoms may only surface hours or days later.

They represent different immune reaction mechanisms and are evaluated from different clinical perspectives.

Q3: Do I need to fast before the test?

No. You can eat and drink normally before the blood draw. No special preparation is required.

Q4: Can children take the 2-in-1 Allergy Check Package?

This package is suitable for adults and children aged 5 or above. For children undergoing testing, it is recommended that a parent or guardian accompany them to the clinic.
