@joyeous I have had quite a few sputum checks over the last few years, only two of which have come back positive and then they were with different strains a month or two apart. The specialist indicated that he thought it was contamination...however I had lost around 6kg in weight in the preceding year. The subsequent 3 tests were all negative, along with further tests I had conducted a few months back. I am at a loss to know why there is such volume of mucus.
