I had my labs today and I noticed this time the DR. ordered diffusion capacity along with the other two regular tests.

I am excited to see how the test comes out. Is this blood test the same DLCO test we get with our pulmonary function tests? Sometimes I cough so much during the tests that I wonder if they are truly accurate and maybe the blood test will prove my DLCO is not so bad afterall?? I am just wishful thinking probably.

Thanks,
Jennifer

Hi Jennifer!

I didn't know a blood test could measure diffusion capacity. Maybe your Dr. wants you to have another PFT?

Sorry I can't be more helpful!

Best,

Claudia

Thanks Claudia...I actually saw the lab sheet though, and there was a check mark by the box that said something like "diffusion capacity". I also had Creatine and another common order. I wish I would have paid more attention to it now. I wonder what it was. Maybe Sweet will know?
Thanks! Oh, and how is the Dominican Republic? I would love to be there right now!! I bet the weather is amazing.

Jennifer,
I checked it out and couldn't find any specific blood test that would check your DLCO. However, an Arterial Blood Gas determines how well your lungs are getting O2 into the blood which is what the PFT DLCO does. Having had a couple of these, it is very painful. They draw blood from an artery, NOT a vein, at the wrist or groin. That's all I could find.

Janey,
I know! That's all I could find after researching it myself, so I thought I'd run it by the gurus. I will let you all know when the mystery is solved. I have a copy of the order somewhere in my mess, if I could just find it.

Thanks very much for looking!
Jen

Hi Jennifer! Janey gave you good info. above.

Yes, the weather is lovely. I'll be celebrating the Spring Break in the mountains, with a temp. of 7 degrees. My Raynauds will have a great time!

You know, in the form where my Dr. checks off for labs he sometimes writes the PFT right there.

Maybe you could send him an e-mail and ask?

Have a great holiday!

Claudia
