Abnormal blood test

Sandy
Ok so went fri for glucose test. She said my ketones in my urine were off but she wasnt worried cuz my sugars were normal. Took my 1hr glucose test and this morning (tuesday) i got a call saying they need to see me before my next appointment which is oct 2nd. I said im guessing i failed the glucose test. She said no you're fine u just had abnormal blood results and we need to give u something, how r u feeling? And i said i guess u cant tell me over the phone? She said no. So im seeing the dr friday. Im wondering what it could be, trying not to stress myself but its hard not to. Could it just be anemia maybe??
