发帖数: 140 | 2 First, the question is about "most likely diagnosis"
Second, a pt with asthma might be normal in PFT when he is not in attack,
although it will worsen gradually later without proper treatment.
Third, besides above data, some other findings might support the diagosis of
asthma, such as abnormal TLC, RV or FEF 25-75%.
Fourth, for the diagnosis of asthma in this pt, a metacholine challenge test
might be very helpful.
Hope it helps. I'm not a pulm specialist though. |
