Accurate Asthma Testing in Phoenix, AZ

Asthma Testing & Care Shaped By Personal Experience

Lindsey’s journey into allergy and asthma care began long before her medical training. As a child, she struggled with undiagnosed asthma. Physical activity meant chest tightness, headaches, and falling behind despite her effort. For years, she believed her limitations were personal, until a school nurse recognized the signs of asthma.  With proper care her breathing improved, confidence returned, and the boundaries she had quietly accepted began to disappear.

That experience shaped the direction of her career. Lindsey became a nurse, then a board certified family nurse practitioner specializing in allergy and immunology. She founded Carefree Allergy with a clear mission: **no one should have to live within unnecessary limits caused by untreated asthma.**

What to Expect During Your Asthma Evalution in Phoenix

Your appointment begins with a focused discussion of your breathing symptoms. We review coughing, wheezing, shortness of breath, chest tightness, exercise intolerance, and nighttime symptoms. Triggers, prior treatments, urgent care visits, and current medications are carefully assessed to understand the full clinical picture.

If asthma is suspected,  spirometry is performed in the office to objectively measure airflow. This test evaluates how well you move air in and out of your lungs. In many cases, testing is repeated after a bronchodilator to determine whether airway narrowing is reversible, which helps confirm the diagnosis.

Because many asthma cases are allergy triggered, environmental allergy testing may be recommended. Identifying triggers such as pollens, molds, dust mites, or animals allows for more precise treatment and improved long term control.

What Is Spirometry and How Does It Work?

Spirometry is a simple, non-invasive breathing test that measures how well your lungs are working. It evaluates:

During the test, you breathe into a device called a spirometer. After taking a deep breath, you blow out as forcefully and completely as possible into a mouthpiece. The machine records airflow and lung volume measurements such as FEV1 and FVC, which help determine whether your airways are narrowed.

In many cases, the test is repeated after using a bronchodilator medication. If lung function improves significantly after the medication, this supports a diagnosis of asthma.

The test typically takes about 20 to 30 minutes, and results are reviewed with you the same day.

• How much air you can inhale
• How much air you can exhale
• How quickly you can exhale

Signs You May Have Asthma

Asthma symptoms can vary from mild to severe and may come and go. In children, asthma may also present as frequent coughing after activity, noisy breathing, or difficulty keeping up with peers during physical activity.

Because asthma and environmental allergies often overlap, identifying allergic triggers through allergy testing can be an important part of the evaluation process.

Common symptoms might include:

• Recurrent wheezing
• Shortness of breath
• Chest tightness
• Chronic coughing, especially at night
• Symptoms triggered by exercise, cold air, pollen, or respiratory infections
• Cough that worsens during allergy season

What Causes Asthma in Arizona?

There is no single cause of asthma, but several factors contribute to airway inflammation and reactivity. In Arizona, the desert climate adds unique challenges: dry air, year-round pollen, dust, and monsoon mold spikes can all trigger and worsen asthma symptoms.

• Environmental allergens such as pollen, dust mites, mold, and pet dander
• Family history of asthma or allergies
• Respiratory infections
• Exposure to tobacco smoke
• Air pollution and desert dust
• Exercise or cold air
• Strong scents or chemical fumes
