Yes, Angela. It will show up in the urine sample. I had mine tested back in September and when I got the results back I saw the 1.5 reading for Ketones in the urine (small / trace).

This might be a good time to let him know what you're doing. You've lost weight, you're feeling good, he's pleased with your progress so far? If all your blood work is glowing then maybe it's time to let him know just how wrong he's been?

Alternatively, because you're fasting you can't eat 12 hours before the test, but you can drink water. You should be able to dilute the concentration a bit, but I think there will still be a trace element left. Exercising the day before and drinking a few litres of water would help lessen the amount though.
