Incomplete?

Called Z's office today. Receptionist said he was in surgery, there was nothing in my file so results must not be back. He'll call me as soon as he hears. So I called Dr. C, would she call over to the hospital and see if anything's back yet? She calls me back a few minutes later to say the path report's not back yet, but it's still early in the day. What's taking so long since last Wednesday?
Z's receptionist called back, the results came in but they're incomplete (what the fuck does that mean?). I asked are they incomplete good, or incomplete bad? She has no idea, but promises Z will call.
I'm still not really nervous about the whole thing, more bemused than anything else. I do, however, hope that by tomorrow this will have all turned out to be a harmless adventure.
