Well, it could have been worse- she could have found some cannibanoids floating around in there! :)

There are 3 possibilities: 1- your urine was high in sugar

                                  2- high in ketones

                                  3- high in both

3 is the most likely to mean diabetes, but it is also potentially dangerous! (then she should have referred you for a blood sugar check immediately) So I'm gonna guess it wasn't 3.

1 is the next most likely, although it could also be from an infection.  So if you're not sick, you should have your blood sugar checked.

2 is the least likely IF you starved before the urine check (starvation raises ketones).

So, you can't diagnose diabetes from urine, without ruling out infection or starvation.  Either way, simply get a blood sugar test, and you'll know for sure.

Best of luck- and remember, even if they hire you, you still can't party because of the random drug testing :)
