They did not tell me what tests they were running they just said " because you have ketones dumping into your urine we would like to run some tests to see what is happening". So I don't know.
"...nurse earlier told me that if my tests were normal..." What test? Did you have a fasting glucose test, blood sugar, urine glucose, glucose tolerance (GTT)? A hemoglobin A1c (HgbA1c) that most doctors use to determine whether the patient is pre-diabetic, a diabetic, or not at all. Answers to these question will help.
Your correction to diet and exercise will play a large part in staying healthy. Keep it up, you'll like yourself more and feel a whole lot better too.
