Allergy Testing – ENT-Focused Diagnosis and Treatment

Allergy testing is a fast, reliable way to identify the cause of symptoms such as nasal congestion, sneezing, itching, or persistent runny nose. An accurate diagnosis allows for targeted treatment—improving breathing, sleep quality, and overall quality of life.

What Is Allergy Testing and How Is It Performed?

If you experience ongoing nasal symptoms and suspect an allergy, professional allergy testing is recommended.

The skin prick test is the most commonly used and most reliable method. A small drop of allergen is placed on the skin of the forearm, and the surface is gently pricked. If you are allergic, redness or swelling appears within 15–20 minutes.

Skin testing is considered the gold standard because it delivers rapid and accurate results. Typically, 10–20 of the most relevant regional allergens are tested. In selected cases, a blood test (specific IgE antibodies) may be used to confirm or further evaluate results.

Common Symptoms and Conditions

Most Common Allergies Affecting the Nose and Airways

  • Allergic rhinitis (pollen, dust mites, house dust): sneezing, runny nose, nasal itching, nasal obstruction
  • Allergic rhinitis in children: a frequent cause of chronic nasal congestion and discharge
  • Seasonal allergies: most common in spring and summer, usually triggered by grass and tree pollen
  • Perennial (year-round) allergies: typically caused by dust mites or house dust

Untreated nasal allergies may be associated with other conditions, including:

  • Nasal polyps – seen in approximately 2–4% of patients with allergic rhinitis, especially those with chronic sinus inflammation
  • Asthma – affects around 20% of patients with allergic rhinitis, particularly with long-standing symptoms or dust-mite allergie

Nasal Congestion and Sneezing – When Should You Suspect an Allergy?

You should consider allergy testing if nasal congestion lasts longer than two weeks, worsens during specific seasons, or is more pronounced indoors.

Additional warning signs include:

  • Nasal itching
  • Fatigue
  • Reduced concentration
  • Recurrent or worsening sinus problems

Spring allergies (cypress, grasses, pine) often cause sneezing and itchy eyes, while dust-mite allergies typically lead to persistent nasal blockage, especially during winter.

What Does Allergy Testing at 4CLINIC Include?

At 4Clinic, allergy testing is combined with a comprehensive ENT examination. We use validated skin prick tests and, when indicated, blood testing.

Based on your results and symptoms, we create a personalized treatment plan, which may include:

  • Antihistamines
  • Local nasal therapy
  • Immunotherapy (desensitization), when appropriate

Why Be Tested by an ENT Specialist?

An ENT specialist evaluates allergy test results in direct correlation with symptoms of the nose, sinuses, and ears. This ensures a precise diagnosis and targeted therapy—treating the cause, not just masking symptoms.

What Are Allergies and Can They Be Prevented?

Allergies are an exaggerated immune response to normally harmless substances such as pollen or dust. While complete prevention is not always possible, symptoms can be significantly reduced through:

  • Early diagnosis
  • Allergen avoidance
  • Proper medical treatment

Allergy Testing and ENT Examination in One Place

At 4CLINIC, allergy testing and a private ENT specialist examination are performed during the same visit. Based on your findings, a tailored treatment and follow-up plan is created for long-term symptom control.

Frequently Asked Questions (FAQ)

Can allergy testing be done in a pharmacy?

Skin testing provides faster results and is the first-line method. Blood tests are used only in specific situations.

When is the best time for allergy testing?

Testing can be done year-round, but it is ideally performed outside peak allergy season

How should I prepare for the test?

Antihistamines should usually be stopped 5–7 days before testing, in consultation with your doctor.

How long does the test take?

The skin prick test takes about 20 minutes, with immediate results.

Which allergies can be detected?

Dust mites, house dust, mold, animal dander, and common airborne allergens such as grass and tree pollen.

Are there any side effects?

Side effects are rare and mild—usually limited to temporary redness or itching at the test site.
