IMPORTANT ANNOUNCEMENT
Dear Patients,
We appreciate the trust and confidence you have in us to care for your health, and we are pleased to announce an upcoming significant change in our practice. Effective MONDAY, AUGUST 31, 2026, we will become part of Spartanburg Regional Healthcare System and Medical Group of the Carolinas (MGC). While our practice names will differ, the physicians and staff, locations, and telephone numbers will remain the same.
Please be aware that all locations will close at noon on Thursday, August 27, 2026, and reopen on Thursday, September 3, 2026, for our offices to transition to MGC. We will also be available all day on Friday, September 4, 2026. We will have limited staff available to answer phone calls and take messages during this time, so we ask for your patience.
Once this transition is complete, it will provide patients with better access to their medical records, appointment requests, and communication through the MyChart patient portal.
Thank you for the opportunity to care for you and for participating in this exciting journey.

Lung Diffusion Testing
Lung diffusion testing measures how well the lungs exchange gases. This is an important part of lung testing, because the major function of the lungs is to allow oxygen to “diffuse” or pass into the blood from the lungs, and to allow carbon dioxide to “diffuse” from the blood into the lungs.
How the Test is Performed
You breathe in (inhale) air containing a very small amount of a tracer gas, such as carbon monoxide. You hold your breath for 10 seconds, then rapidly blow it out (exhale). The exhaled gas is tested to determine how much of the tracer gas was absorbed during the breath.
How to Prepare for the Test
Do not eat a heavy meal before the test.
Do not smoke for at least 4 – 6 hours before the test.
If you use a bronchodilator or inhaler medications, ask your health care provider whether or not you can use them before the test.
How the Test Will Feel
The mouthpiece fits tightly around your mouth. Clips are put on your nose.
Why the Test is Performed
The test is used to diagnose certain lung diseases, and to monitor the status of people with established lung disease. Repeatedly measuring the diffusing capacity can help determine whether the disease is improving or getting worse
