How Can Breathing Tests Help With Allergies?

Allergies are not only the culprit for itchy skin or sneezing but also respiratory problems, as the most common type of asthma is caused by allergies. Substances like dust mites, pollen or pet dander are not only responsible for triggering your hay fever symptoms but they can also cause asthma signs and symptoms.

Allergies, inflammation or asthma are just a few of the conditions to blame for breathing problems: 8.3% of Americans have asthma, out of which 20.4 million are adults and 6.1 million are children.

Since breathing problems and allergies have so much in common, let’s check what allergy doctors say on how breathing tests can help with your allergy symptoms.

1. What is an allergy breathing test?

Allergens and viruses can enter your lungs through your nasal passage, and sinus inflammation triggers asthma attacks, which, on the other end, are triggered by allergies. Since everything is correlated, having an allergy breathing test is key in determining the right diagnosis.

An allergy breathing test or a pulmonary function breathing test is used by an allergist specialist or asthma doctor to diagnose and treat breathing conditions, like chronic sinusitis, influenza, allergies or asthma. If you notice you have problems with your breathing and symptoms like chest pain, fatigue or chest pain, talk to your doctor immediately, as some cases might require urgent treatment.

2. What is Spirometry?

Spirometry is a diagnostic tool used to check how allergies and asthma can affect the air capacity of the lungs and the bronchial airways. Routine spirometry is very efficient in detecting subtle changes in the patient, which can be overseen by only a physical examination.

2. What other Pulmonary function tests are there?

PFTs or pulmonary function tests are non-invasive tools used to determine how well the lungs are working and usually measure capacity, volume, or gas exchange. These tests are a very important part of getting the right diagnosis and treatment in case of respiratory problems, even for those caused by allergies. Apart from spirometry, these are other of the few pulmonary tests used by physicians:

  • Arterial blood gas test.
  • Lung volume test.
  • Six-minute walk test.
  • Exhaled nitric oxide test.
  • Body plethysmography.
  • Methacholine inhalation challenge.

To prepare for your pulmonary function test, it is recommended not to smoke or have heavy meals hours before the test, not wear tight clothing, and if you are on certain medication, you might be asked to not take any a few hours before your appointment.


For allergy sufferers, breathing problems are a serious issue and can be caused by allergens like pollen, dust mites or mold. Seeing a specialist is essential as they could recommend allergy breathing tests that can help determine the right diagnosis and treatment.
