Had my first PFT

Recommended Posts

So after lung x-ray and CT scan that didn't show much, I had my first PFT. I did pretty well, but the guy that did it said my oxygen absorption was 'typical' of people who have sclero. (this is the test where you breathe in the gas, and exhale).


Now I'm worried and still have a few weeks to go before I see my doctor. I realize you aren't doctors but does anyone have any extra information? Does that guarantee that I have lung involvement? What could cause that particular test to be worse than the others?

Hi Omaeva,


What I think you might be talking about here is a diffusion defect.


If the thickness of the alveolar wall increases – such as in pulmonary fibrosis or pulmonary edema, for example, the diffusion capacity is lower. The alveoli are where the gas exchange (O2 for CO2) occurs. If the alveolar wall is thickened there would be less space for the gases.


If your other tests were normal, then this portion of the PFT might be indicative of VERY EARLY fibrosis. I say 'might' because there is no way I'm qualified to diagnose. If that is the case, you are actually lucky because as you will keep hearing, early diagnosis is the key.


When I hear something during a test that worries me, I call the doctor's office and say something like: "The tech says my red hair doesn't look natural. I know Dr. Somebody might not have seen the test results yet, but would you tell him I'm extremely concerned and ask him to give me a call at his convenience?" I don't like worrying unnecessarily - the stress gives me wrinkles. :lol:


Best wishes on this. Let us know how you get on, won't you?

Hi omaeva,


I'm glad you had a PFT, but I'm just curious why you must wait so long before you see your dr?


Secondly, Jeannie did an awesome job explaining what may have been implied, by the person who gave you the PFT.


I also agree, that it would not be unreasonable for you to call your dr's office to get the results and his input, to your satisfaction. Like you...and Jeannie, I sure wouldn't want to have to wait if I was worried about the translation of a test.


Please let us know when you hear?

Special Hugs,

Susie thank you.

I'm waiting so long because it's supposed to be my quarterly check up, and I needed to get my PFT and blood work done before I came in, and just got scheduled that day. I'm anxious but only a little more than week away. I'll definitely check in here once I know more.
