Recently I had my blood test which showed elevated FASTING plasma glucose 108 mg/dL. I never had sugar earlier nor it runs in my family. Past 1 year I had it checked 3 times and results were 85, 87, 87 mg/dL respectively. But now it's showing 108. Also my post prandial plasma glucose (2 hours) is 112 mg/dL. And result is negative. How come I have 108 fasting sugar with such low post prandial sugar? Is it a lab investigation error?

Mr. lybrate-user, Thanks for the query. Some times there could be a slight variation in glucose levels. Even 106 mg, does not show that there is diabetes. Your PP is excellent. There is no reason to worry. You may do next check if needed after a year or so. Thanks.
