Glucose in my urine, but a normal blood sugar test, which is a sign of diabetes?

In brief: Maybe both

Aside from diabetes, there are other less common reasons to spill glucose in the urine.
However, the bladder collects urine over several hours at which time a blood sugar may have been transiently elevated. Therefore, even if a blood sugar is normal at one point in time, urine represents hours of time.

In brief: Neither

A normal blood test rules out diabetes.
There are other reasons for sugar in the urine besides diabetes.

In brief: It means high bs

The presence of glucose in urine can only be explained by high bs in the blood that exceeds renal capacity for glucose reabsorption ( which is around 180mg/dl).
Having said that, you should seek an endocrine evaluation to find out your bs trends and if you are at risk for diabetes. On final note, renal disease can also lead to leaky kidneys which loss of electrolytes, Amino Acids etc.

Best thing would be to get this evaluated further, since all tests can have false positives/negatives, and there can be other things going on with the kidneys besides diabetes. If worried about diabetes, today is a good day to start making healthy changes to prevent diabetes. You can start here: http://www.diabetes.org/are-you-at-risk/lower-your-risk/?loc=atrisk-slabnav
