is smoking during fasting hours before fasting blood test increases the blood sugar in the test?

It shouldn't: Smoking a cigarette before a blood test should not increase your sugar level. Thus, i would discuss with your doctor why your sugar was elevated as this may be the first sign of diabetes. Good luck!
