Final answer:
The normal range for random/casual glucose levels is between 60-180 mg/100 ml. Values outside of this range may indicate a problem. High levels may suggest hyperglycemia or diabetes, while low levels may suggest hypoglycemia.
Step-by-step explanation:
The normal range for random/casual glucose levels can vary depending on the context. In general, a normal fasting or post-absorptive glucose level is between 60-90 mg/100 ml of blood. After meals, blood glucose levels can range between 100-140 mg/100 ml. Random blood glucose levels, measured at any time after a meal, can range from 100-180 mg/100 ml.
Values outside of these ranges may indicate a problem. For example, consistently high blood glucose levels may be a sign of hyperglycemia or diabetes. Blood glucose levels below the normal range, especially during fasting, may suggest hypoglycemia.
