Doctor taking a blood sample from a patient

Looking at:

Several substances in your blood that are ‘markers’ or signs that you could be at risk of developing PAH.1

What to expect:

A doctor or nurse will use a small needle to collect a blood sample from you. They will let you know if you need to do anything to prepare, such as not eating (fasting) etc.
