Final answer:
A normal fasting blood glucose (FBG) level is typically between 60-90 mg/100 ml of blood in the fasting or post-absorptive state. After meals, the blood glucose level can rise to 100-140 mg/100 ml. A fasting level below 100 is considered normal, while a level between 100 and 125 is considered pre-diabetes, and a level above 125 indicates diabetes.
Step-by-step explanation:
A normal fasting blood glucose (FBG) level is typically between 60-90 mg/100 ml of blood in the fasting or post-absorptive state, which is about 12-14 hours after a meal. After meals, the blood glucose level can rise to 100-140 mg/100 ml. A fasting level below 100 is considered normal, while a level between 100 and 125 is considered pre-diabetes, and a level above 125 indicates diabetes.
