Question
Can a finger prick test confirm diabetes?
Answer
The diagnosis of diabetes primarily relies on blood sugar levels, which are typically slightly lower in finger blood compared to venous blood. Based on your condition, it is recommended to undergo a postprandial blood sugar test, as the blood sugar levels of diabetes patients usually rise first after eating. If your condition is not severe, a blood sugar level of 7.0 or above indicates impaired pancreatic function, but it is not yet sufficient to confirm diabetes.
