Pulmonary & Lung Function Tests in Alpharetta & Cumming, GA
Breathing is something most of us take for granted — until it becomes difficult. At Metro Medical Associates in Cumming, GA , Alpharetta, GA, we offer on-site pulmonary function testing (PFT), including spirometry, to assess how well your lungs are working and help diagnose or monitor respiratory conditions. Early detection of lung disease leads to better outcomes and an improved quality of life.
Book OnlineWhat Are Pulmonary Function Tests?
Pulmonary function tests (PFTs) are a group of non-invasive breathing tests that measure various aspects of lung capacity and airflow. They help your physician assess how well your lungs take in air, how efficiently they transfer oxygen to the bloodstream, and whether breathing passages are obstructed or restricted.
Spirometry at Metro Medical Associates
Spirometry is the most common and clinically important pulmonary function test available at Metro Medical Associates. During the test, you breathe into a mouthpiece connected to a device called a spirometer, which measures:
- FEV1 (Forced Expiratory Volume in 1 second) — how much air you can forcefully exhale in one second
- FVC (Forced Vital Capacity) — the total amount of air you can forcefully exhale after a deep breath
- FEV1/FVC ratio — the relationship between these values, which helps differentiate obstructive from restrictive lung disease
Spirometry is simple, quick, and requires no radiation or invasive procedures. Results are available immediately and reviewed by your physician during your visit.
Conditions Diagnosed and Monitored with Lung Function Tests
Pulmonary function testing at Metro Medical Associates plays a key role in diagnosing and managing:
- Asthma — identifies airway obstruction and measures reversibility with bronchodilators
- Chronic Obstructive Pulmonary Disease (COPD) — including emphysema and chronic bronchitis
- Restrictive Lung Disease — conditions that limit lung expansion, such as pulmonary fibrosis
- Occupational Lung Disease — for patients exposed to dust, chemicals, or asbestos
- Pre-operative respiratory assessment for patients undergoing surgery
- Monitoring the progression of known lung conditions and treatment response

Frequently Asked Questions — Pulmonary & Lung Function Tests
What is spirometry and how is it performed?
Spirometry is a simple breathing test in which you breathe into a mouthpiece attached to a spirometer. You will be asked to inhale as deeply as possible and then exhale as forcefully and quickly as you can. The device records your lung volumes and airflow speeds. The test typically takes 15 to 30 minutes and requires no needles, radiation, or invasive procedures.
Who should get a pulmonary function test?
Pulmonary function testing is recommended for patients experiencing persistent shortness of breath, chronic cough, wheezing, or recurring respiratory infections. It is also advised for smokers and former smokers, patients exposed to occupational lung hazards, those with a family history of COPD or asthma, and as part of a pre-operative evaluation. Call (770) 777-0750 - Cumming Office or (770) 777-0750 - Alpharetta Office to discuss whether testing is appropriate for your situation.
Does spirometry hurt?
No. Spirometry is entirely non-invasive and painless. You may feel slightly lightheaded or short of breath immediately after the forceful exhalation effort, but this passes quickly. There is no radiation, no needles, and no recovery time required.
How do I prepare for a lung function test at Metro Medical Associates?
Before your pulmonary function test, avoid smoking for at least four hours beforehand. If you use an inhaler, your physician may ask you to withhold it before the test to obtain a baseline measurement. Wear comfortable, loose-fitting clothing, avoid heavy meals for two hours prior, and refrain from strenuous exercise on the day of testing. Our staff will provide specific preparation instructions when you schedule at (770) 777-0750 - Cumming Office or (770) 777-0750 - Alpharetta Office .
What do abnormal spirometry results mean?
Abnormal spirometry results indicate that your airflow is obstructed (as in asthma or COPD) or that your lung capacity is restricted (as in pulmonary fibrosis or chest wall conditions). Your Metro Medical Associates physician will review your results with you, explain what they mean for your health, and develop a personalized treatment plan. Additional testing or specialist referral may be recommended.
Can Metro Medical Associates monitor my asthma or COPD over time?
Yes. Spirometry at Metro Medical Associates is an excellent tool for monitoring the progression of chronic respiratory conditions and assessing whether your current treatment is working effectively. Regular testing helps your physician make timely adjustments to your care plan. Combined with our telehealth options, ongoing respiratory management is convenient and accessible.
Does insurance cover pulmonary function tests?
