what i don't get is that sample A looks like un-infected mucus to the untrained eye (me!), it's not even coloured, if i hacked up something that looked like that i'd be well proud of my lungs.
Then the mucoid looks absolutely disgusting, although yellow rather than green - i've always been told pseudo looks green.....maybe i'm colour blind, but sadly, what i cough up looks like the mucoid for sure <img src="i/expressions/face-icon-small-disgusted.gif" border="0">
