There are a number of different tests you can do for diabetes, and a number of different blood tests.
If you were made to fast (i.e. told not to eat/drink anything overnight/in the morning) then that sample is more accurate than a non-fasted sample (random sample); so a normal result is good news. If you didn't have to fast, a normal result is of course still good news, but the result is slightly less accurate.
If you had 3 samples taken (3 vials) then you may well have had a second diabetes test done in a separate vial which shows how your blood sugar has been over a longer period (~3 months), so again a normal result would be good news.
As for pee samples they seem to be more done for monitoring how people who've been diagnosed with diabetes are getting on with their control, rather than for newly diagnosing people. At least as far as my experience has been with it so far.
Here's a good site with some information that is likely better at explaining it all than me:
