Fasting blood sugar level: 111-125 mg/dl
Postprandial blood sugar level: 141-199 mg/dl

WHO criteria: fasting plasma glucose level from 6.1 mmol/l (110 mg/dL) to 6.9 mmol/l (125 mg/dL) indicates that you have no diabetes mellitus.
Diabetes is diagnosed with the following blood tests:--
Fasting blood glucose level -- diabetes is diagnosed if it is higher than 126 mg/dL two times
Random (nonfasting) blood glucose level -- you may have diabetes if it is higher than 200 mg/dL, and you have symptoms such as increased thirst, urination, and fatigue (this must be confirmed with a fasting test)
Oral glucose tolerance test -- diabetes is diagnosed if the glucose level is higher than 200 mg/dL after 2 hours
Hemoglobin A1c test
Normal: Less than 5.7%
Pre-diabetes: Between 5.7% and 6.4%
Diabetes: 6.5% or higher

If this is not a troll question then you need to get some education about diabetes. 104 is a good number, something I'd like to see a lot of for myself.

AM or random?
Morning blood sugars tend to be higher because the body is just coming off of its maintenance schedule - which kicks in as your body begins its time of prolonged inactivity (sleep).
Maintenance requires a lot of energy and the brain provides this by having the liver produce more sugar. Usually, this results in more than what is needed, and the excess shows up as a higher reading in the morning.It's commonly called "the Dawn Phenomenon".As suggested by someone else, this is far from a concerning issue, so there's nothing to worry about. I just thought you might be interested in the cause of higher morning blood sugar readings as opposed to readings after you've been active.

100 is considered normal. Low would be 70 or less. High would be 200 or higher.
