Last spark from the ashes

Seems they have both, to go by how the doctor's curious glance shifts to understanding. Blaze has other priorities. "If it's the kind of story where I get to fight a dragon, I'm in. 'Course, it might be hard to find a live one."

Everyone gets to crowd around the screen, although Dr. Saab moves over to show the results to Verity. They're getting the allergens out of the way first. "Thank you, Ghost. This is about what I'd expect. You're showing a probable allergy to dregplate - which is a kind of cheap construction metal used in some parts of the City. Not very surprising, so don't worry. About four humans in five have that one. You probably won't actually come into contact with it, but that's just something to be aware of, hm?"

He switches over to the combined antigen/microbe analysis - and Verity might be interested to note that most of the little ID tags on the list are highlighted in green and flagged as match. Most of the rest are in yellow and flagged as 'derivation traced'. The doctor makes a lot of 'mmhmm' noises as he scrolls down, stopping to check the yellow flags as he goes. These all seem to be bugs Verity has had, or ben immunized against - or in the case of a mild flu strain, carries - that are identified by probable relatives or descendants already in the database.
