No matter the season, allergies can hit at any time. In winter, you may experience the classic symptoms of sneezing and a runny nose. This could be due to the icy cold air, or it could be an indication of an underlying allergy. In spring, your eyes might itch or water, or you might have a skin reaction or rash when coming into contact with certain materials.

So you may often find yourself wondering, “Is this just seasonal, or do I have an allergy?”

If you’re unsure of the cause of your symptoms, a test for allergy can help identify possible triggers and begin a process of elimination. In Spain, requesting medical examinations can seem like a minefield, so below we explain the key facets of allergy testing in Spain.

When should you consider an allergy test?

In many cases, you can be allergic to something and not know it, especially these common allergy types. In Spain, pollen allergies are especially prevalent in inland regions due to agriculture and dry conditions.

Allergies are not necessarily linked to family history, although it can be a factor. There are numerous cases of children with allergies whose parents do not suffer from any. Additionally, you can develop allergies at any age, and symptoms can come and go, disappear or worsen.

If you’ve been suffering from any of the symptoms below, speak with a medical professional about whether allergy testing may be appropriate:

• Red, watery or itchy eyes
• Mucus, sneezing or a swollen nose
• Coughing, asthma attacks or breathing difficulties
• Dry, red or irritated skin, small welts or burning skin
• Sudden heartburn, vomiting or diarrhoea

Treatment depends on the type and severity of the reaction. Severe symptoms, especially breathing difficulties or signs of a serious allergic reaction, require urgent medical attention. Knowing your allergy history and triggers can help you reduce the risk of future reactions.

Common types of allergy tests: Prick tests vs. Blood tests

Two common approaches to allergy testing may be used depending on your symptoms and suspected trigger: the skin prick test and the blood test.

Consult the table below to discover the different characteristics of each test for allergy.

First, consult your insurance provider to see which allergy tests might be covered under your health insurance policy.

How to prepare for your allergy appointment  

• Your GP may then refer you to a doctor specialising in allergology. In the public system, the process can involve waiting for a specialist appointment.

• You are normally contacted later with the available appointment options. Waiting times vary according to the region, demand and specialist availability.
• Before the appointment, write down your symptoms and when they occur, possible triggers, your personal and family allergy history, and all medicines, vitamins and supplements you take.
• Ask the clinic in advance whether you should stop antihistamines or any other medication before testing and for how long. Do not stop prescribed medication unless a healthcare professional tells you to.
• At the appointment, the allergist will review your history and determine which type of allergy testing is most suitable.

Allergy testing is generally safe when carried out by trained healthcare professionals. Serious reactions are uncommon, but some medicines can interfere with skin-test results. Follow the clinic’s instructions carefully, particularly regarding antihistamines and other medication before your test.

Allergy testing through private health insurance vs. public health system 

Public system 

In Spain’s public healthcare system, you will usually start with primary care and may be referred to an allergy specialist if necessary. Access and waiting times vary by autonomous community and demand, and specialist appointments can involve a significant wait.

For expats who are not confident in Spanish, communication may also be a concern, as the availability of English-speaking staff or interpretation services can vary between clinics. If language is a barrier, ask the health centre what support is available or consider taking a Spanish-speaking companion.

Private insurance 

If long waiting times in the public healthcare system are a concern or you simply want to speed up the process, private health insurance can provide faster access to an allergist (alergólogo) and diagnostic testing, subject to the terms, coverage, waiting periods and authorisation requirements of your policy.

Our private healthcare plans provide access to specialist medical care and diagnostic services. Check your specific policy to confirm which allergy tests are included and whether prior authorisation is required.

One of the advantages of private cover can be quicker access to diagnostic tests, helping allergy specialists investigate the type of reaction you may have. Below, discover our wide variety of healthcare coverages:

• Integral: Perfect family health insurance.
• Adapta + Sonrisa Esencial: No co-pay health insurance that includes dental healthcare.
• Adapta + Sonrisa Esencial + Repatriation: Health insurance including repatriation coverage.
• Medica: Medical insurance designed to complement Social Security in Spain.
• Prestigio: Comprehensive health insurance with reimbursement.
• Salud 60+: Health insurance for ages 60 and over, with no age limit and regardless of health status.

What do your allergy test results mean? 

• Positive allergy test: Means your body has shown sensitisation to the substance tested. However, a positive result does not automatically mean that the substance is responsible for your symptoms. Your allergist will interpret the result together with your medical history and the reactions you have experienced.
• Negative allergy test: Means the test did not detect sensitisation to the allergen tested, but it does not always rule out an allergy. Depending on your symptoms and the type of test used, your specialist may recommend additional testing.

False-positive and, less commonly, false-negative results can occur. This is one reason allergy results should not be used for self-diagnosis. Always discuss the results with a qualified medical professional from our Medical Team before eliminating food, changing medication or making other significant health decisions.

If allergy symptoms are affecting your day-to-day life, a test for allergy can help your doctor investigate possible triggers and decide what to do next. Spain offers allergy assessment through both the public healthcare system and private providers. For expats who want shorter waits or more direct access to specialists, private health insurance may be a convenient option, depending on the cover included in the policy.
