How do blood tests help diagnose idiopathic pulmonary fibrosis (IPF)?

ANSWER

They're used to check your oxygen and carbon dioxide levels.

Your doctor takes blood from an artery on the inside of your wrist, arm, or groin. It may be slightly more painful than a regular blood test, which takes a sample from your veins.

You may feel some discomfort. You'll need to sit calmly and keep pressure on the spot for a few minutes afterward to keep it from bleeding.
