Well, if you save it, you'd mostly be doing that to show them its color and get them to take your complaint seriously. They'll really need a fresh sample to look at the microbiology, so you'd have to provide that when you went in. Definitely suggest to them that, considering you're coughing up what looks like blood (here's where you can hold up the saved sample or handkerchief or tissues), you'd like them to look at the pathology under a microscope so they can prescribe the right medicines if you require any. Then offer to cough up a fresh sample for the lab.
