Patient's question:
What tests can diagnose diabetes? Is a finger blood test accurate?Doctor's answer:
Diabetes is about checking blood sugar levels. Finger-prick blood glucose values are generally a bit lower than those from venous blood. Advice: In your case, I recommend checking a post-meal blood glucose level. Typically, people with diabetes first show elevated post-meal blood sugar. If it's not severe, a 7.0 reading indicates impaired insulin function, but it doesn't confirm a diabetes diagnosis.
