@mikejj244 You pretty much described me how I was for almost a decade without a diagnosis other than asthma. Very frustrating. Are you getting treatment for the bronchiectasis at one of the Bronchiectasis Centers? You can check to see if your health care facility is on the list. If not, you can search for one closest to you. It is imperative to be get treatment at one of these specialty centers. I read today that Baylor University Medical Center (Dallas) was just added to the list. Also a well known and established center is at UT Tyler. General pulmonologists are just that and typically not up to speed on BE. For example, one of the BE centers would likely induce a sputum sample in office since you have been unable.

Yupelri is a anticholinergic and can be very drying to the lung secretions, which might contribute to your difficulty producing a sample. Before I made it to a specialty center my general pulmonologist wanted me on Spiriva, which is an anticholinergic and made clearing my lungs next to impossible.
