Measure How Your Lungs Are Performing

Pulmonary Function Testing in Tyler evaluates lung capacity and airflow to support accurate asthma diagnosis and management.

If you have asthma or suspect you do, understanding how your lungs are functioning gives your provider the objective data needed to guide treatment. In Tyler, where humidity and seasonal allergens make lung monitoring especially important for asthma patients, pulmonary function testing provides measurable insight into your respiratory health. The test shows how much air your lungs can hold, how quickly you can move air in and out, and whether your airways are restricted.

Access Allergy and Immunology - East Texas performs pulmonary function testing in-office using calibrated diagnostic equipment. The test is non-invasive and typically involves breathing into a device called a spirometer, which records your lung performance in real time. Objective measurements help determine severity, monitor treatment response, and guide medication adjustments. Results are reviewed with you to create or refine a personalized asthma management plan.

If you need to understand how your lungs are working and whether your current treatment is effective, contact Access Allergy and Immunology - East Texas in Tyler to schedule pulmonary function testing.

Testing Captures Real Data About Airflow and Capacity

During your visit in Tyler, you will be asked to breathe into a mouthpiece connected to the spirometer while following specific instructions from the technician. You may be asked to take a deep breath and exhale as hard and fast as possible, or to breathe normally for a set period. The device measures how much air you move and how quickly, and the data is displayed immediately for your provider to review.

Once testing is complete, your provider will explain what the numbers mean and how they relate to your symptoms. You will see whether your airways are obstructed, how well your lungs are expanding, and whether your current medications are controlling your asthma effectively. Regular testing supports safer, more effective long-term respiratory control.

Pulmonary function testing is often repeated over time to track changes in your lung health and adjust treatment as needed. If your asthma worsens or improves, the test results provide clear evidence of that change. This ongoing monitoring is especially valuable for patients in Tyler dealing with seasonal flare-ups or those adjusting to new medications or environmental conditions.

Let's Address What You're Wondering About

These are the questions patients in Tyler typically ask before their first pulmonary function test, covering what happens during the visit and how the results are used.

What does pulmonary function testing measure?
The test measures lung capacity, airflow speed, and how efficiently your lungs move air in and out. These measurements help your provider assess asthma severity and determine whether your airways are restricted.
How long does the test take?
Pulmonary function testing usually takes about 15 to 30 minutes, depending on the number of breathing maneuvers required. You will receive your results during the same visit and review them with your provider.
What should I do to prepare for the test?
Your provider may ask you to avoid using your inhaler or other respiratory medications for a few hours before the test so the results reflect your baseline lung function. You will receive specific instructions when you schedule your appointment.
Why is this test important for asthma patients?
Objective measurements help determine severity, monitor treatment response, and guide medication adjustments. Without testing, it is difficult to know whether your asthma is well-controlled or if your treatment plan needs to change.
When should I have pulmonary function testing done?
Testing is recommended when you are first diagnosed with asthma, when your symptoms change, or periodically to monitor how well your treatment is working. Your provider in Tyler will let you know how often you should be tested based on your condition.
