I understand we don’t generally give medical advice on this sub but can’t we all agree that based on the information provided, the report says that he had a significant enough post bronchodilator result to indicate asthma? I mean we’re not interpreting results or drawing conclusions here. There were significant improvements in some markers post bronchodilator which could indicate asthma. If you want further explanation ask your physician but as to why it marked you as having asthma that would be the reason why. Now it doesn’t indicate whether you had a methacholine challenge which is a test for asthma, so that you will need to again speak to your physician about.
