Exploring Allergy Blood Testing and the ALEX® 2.0 Allergy Screening Blood Test

Allergy blood testing is an essential tool for diagnosing and managing allergies. By identifying specific allergens that trigger reactions, you can avoid these triggers and manage your health more effectively.


At One Day Tests, we are dedicated to making health monitoring both accessible and efficient. Our approach includes the ALEX® 2.0 Allergy Screening Blood Test, which offers extensive and accurate insights into various allergens.


With our state-of-the-art blood kits and innovative Health Dashboard, we ensure quick, reliable results, empowering individuals to take proactive steps towards better health management.

Allergy reactions

Understanding Allergy Blood Testing

Allergy blood tests, primarily IgE antibody tests, measure the levels of immunoglobulin E (IgE) antibodies in the blood. These antibodies are produced by the immune system in response to specific allergens. By identifying elevated IgE levels, these tests can pinpoint which substances trigger allergic reactions in an individual.


Unlike skin prick tests, which involve exposing the skin to potential allergens and observing reactions, allergy blood tests require a simple blood sample. This makes them particularly useful for individuals with skin conditions, those on medications that interfere with skin testing, or individuals who prefer a non-invasive method.

Benefits of Blood Tests for Allergies


Allergy blood tests offer several advantages over skin tests:

  • Less-invasive: A blood test is less invasive than skin tests, reducing discomfort.
  • Broad Range of Allergens: These tests can screen for a wide variety of allergens from a single blood sample.
  • Convenient: Blood tests can be performed even if the patient is on medications that could affect skin test results, making them more accessible for continuous monitoring.


By utilising allergy blood tests, such as the ALEX® 2.0 Allergy Screening Blood Test offered by One Day Tests, you can gain comprehensive insights into your allergies, facilitating better management and improved quality of life.

What is the ALEX® 2.0 Allergy Screening Blood Test?

The ALEX® (Allergy Explorer) 2.0 Allergy Screening Blood Test is an advanced diagnostic tool capable of rapidly and reliably testing for up to 295 allergens, including 120 extracts and up to 180 allergen components, simultaneously from a single blood sample. This comprehensive analysis is invaluable for assessing complex allergy cases.


How It Works


The ALEX® 2.0 utilises a multi-parameter allergy diagnostic method, covering almost all globally relevant allergens in one test.


By measuring both specific IgE (sIgE) and total IgE, the ALEX® 2.0 provides detailed information about your allergy profile. This molecular allergology approach offers enhanced diagnostic depth compared to conventional extract-based tests. It helps healthcare professionals better define individual IgE profiles and tailor strategies, especially for food allergies.

Why Is It Important to Test for Allergies?

The ALEX® 2.0 Allergy Screening Blood Test analyses a broad range of allergen extracts and molecular allergens. These include:

  • Pollen: Various types that trigger hay fever.
  • Mould: Includes Malassezia sympodialis, linked to atopic dermatitis.
  • Fungus: Associated with skin diseases.
  • Mites: Common in household dust.
  • Pets: Proteins from cats, dogs, and other animals.
  • Insects: Venoms and other allergens.
  • Foods: A wide array of common food allergens.

Understanding which specific allergens trigger your symptoms is essential for effective allergy management. Identifying your allergens allows you to:

  • Avoid Triggers: By knowing what substances to avoid, you can reduce exposure and minimise allergic reactions.
  • Personalised Treatment Plans: Healthcare providers can develop tailored management strategies and treatments based on your specific allergy profile.
  • Improved Quality of Life: With accurate identification and proper management, you can significantly enhance your overall well-being and reduce the impact of allergies on your daily life.


The detailed insights provided by the ALEX® 2.0 Allergy Screening Blood Test enable more precise and effective allergy management, helping individuals take proactive steps towards better health.
