COPD

I just had a chest x-ray sent to my physician. I am unable to have the TB test due to exposure to the TB virus many years ago. I was to have chest x-rays every year, but...well, I did not! I am 49. Exercise moderately, am not overweight, NEVER smoked in my life, yet my Doctor's nurse told me over the phone I have COPD and I need to come immediately. I have neve had any problems connected with the symptoms of COPD.

I trust my Doctor and am anxious to hear what she says. But, I have a few questions.
1. Does a pulmonologist read a chest x-ray before sending it to the DR.?
2. Can COPD be misdiagnosed?
Thanks

In your case, the chest x-ray is most likely to be read by a tuberculosis (TB) screening doctor, by your doctor or by a radiologist.  It is unlikely to have been read by a pulmonologist, unless one happens to be the reader for your local public health department.  Chronic obstructive pulmonary disease (COPD) can and is frequently misdiagnosed on the basis of chest x-ray findings.

A chest x-ray may suggest COPD but the best way to make the diagnosis is by lung function testing called spirometry.  Never having smoked and, presumably not having been exposed to occupational toxins or other hazards, it would be very unlikely that you would have COPD.  The suspicion of COPD is not an urgent matter, except for your peace of mind.  When you see your doctor, you should ask for the basis of the conclusion that you have COPD and request spirometry.  This is a simple breathing test that provides detailed information about how the lungs are working.  Often it will identify a problem in your lungs before you have symptoms.  When this is done periodically it will tell about the health of your lungs over time.

The definitive test to determine the extent of COPD will be a PFT test. (pulmonary function test). Usually done at the pulmonologist office or hospital. Normally along with a CT scan. Also a 6 minute walk to determine if your O2 stats are getting below 88-90.
