Diagnosis

Environmental allergies affect millions of people worldwide and can cause bothersome symptoms such as sneezing, itching, nasal congestion, and difficulty breathing. Environmental allergy tests are medical tests designed to identify substances in the environment that trigger allergic reactions.

What are Environmental Allergy Tests?

There are different methods to detect environmental allergies, but the most common are:

· Skin test or prick test: Small drops of allergens are applied to the skin and the reaction is observed. If redness or swelling appears, it means there is sensitivity to that substance.

· Blood test (specific IgE): This measures the amount of IgE antibodies in the blood in response to specific allergens.

· Patch test: This is used to detect contact allergies by applying substances to the skin for 48 hours.

What Allergies Can These Tests Detect?

Environmental allergy tests can identify sensitivities to:

· Dust mites

· Pollens from trees, grasses and weeds

· Fungi and molds

· Animal dander and epithelia (dogs, cats, horses, etc.)

An allergy test is recommended if you experience symptoms such as:

· Persistent nasal congestion or frequent sneezing
· Itching in the eyes, nose, or throat
· Difficulty breathing or wheezing
· Skin rashes or hives with no apparent cause

If you experience these symptoms seasonally or permanently, an environmental allergy test can help you identify triggers and improve your quality of life through specific treatments.

The prick test is a rapid and effective skin test for diagnosing allergies to environmental and food substances. Before performing it, it is important to meet certain requirements to ensure its accuracy.

At what age can a prick test be performed?

The prick test can be performed from birth in cases of food allergies, and in the case of environmental allergies, it is usually performed from the age of two, although in some cases it can be performed earlier if the specialist deems it necessary. There is no minimum or maximum age for performing it.

Medications to avoid before the test

For reliable results, it is recommended to discontinue certain medications that can interfere with the allergic skin reaction:

· Oral antihistamines (loratadine, cetirizine, ebastine, fexofenadine, etc.) → Avoid for 5 to 7 days before the test.
· Allergy or cough syrups with antihistamines → Stop taking them 5 to 7 days before the test.
· Oral or injected corticosteroids (in high and prolonged doses) → Consult your doctor.
· Tricyclic antidepressants → Some may affect the result; it is important to discuss this with your specialist.

Important:

· Corticosteroid creams or inhalers DO NOT affect the result and can continue to be used.
· If you have questions about your medication, consult your doctor before stopping any treatment.

How is the prick test performed?

· Small drops of allergen are applied to the skin of the forearm or back in children.
· A light superficial scratch is made so that the substance comes into contact with the immune system.
· Wait between 15 and 20 minutes to observe the reaction.
· If redness or swelling appears in the area, the allergy to the tested allergen is confirmed.

The prick test is painless, safe, and provides immediate results, allowing for a quick diagnosis so you can begin appropriate treatment.

The ALEX² Test is the most advanced allergy test on the market, based on molecular component-based diagnosis. With a single blood sample, it analyzes more than 295 allergens and accurately detects not only the presence of allergies but also the degree of sensitivity to each of them.

What is the ALEX² Test?

Unlike traditional tests, the ALEX² Test is a cutting-edge blood test that uses nanotechnology to identify both complete allergen extracts and individual molecular components. This allows for a more accurate and personalized diagnosis, facilitating more effective treatment.

What allergies does the ALEX² test detect?

This test covers a wide range of allergens, including:

· Environmental allergens: Pollens, dust mites, animal dander, fungi, and molds.
· Food allergens: Fruits, nuts, seafood, dairy, eggs, cereals, among others.
· Other allergens: Insect bites, latex, and more.

In addition, thanks to its molecular diagnostic technology, the ALEX² Test differentiates between primary sensitizations and cross-reactions, avoiding unnecessary restrictions in diet and lifestyle.

Advantages of the ALEX² Test

✔ Analysis of more than 295 allergens in a single test.
✔ Precision molecular diagnosis, differentiating between true allergies and cross-reactions.
✔ Just one blood sample, no need for exposure to allergens.
✔ Detailed and personalized results, facilitating more effective treatment.
✔ Ideal for people with complex allergies or multiple sensitizations.

Who is the ALEX² Test indicated for?

This test is ideal for:

· People with allergy symptoms without an identified cause.
