Hi there,
I suggest that you purchase a self-test kit for Diabetes2 called A1C NOW
made by Bayer, This home test kit is VERY acurate. Last week, it was sold at Walmart for 23 dollars. The latest news is that 30% of adult Americans, 79 millions adults, is either pre-diabetic 2 or diabetic 2 already. Good luck
"No one in my family has diabetes."
Neither do you.
"Should I be concerned?"
No, your levels are well within normal acceptable ranges. In nondiabetic individuals glucose peaks ∼60 min postprandial [after a meal], rarely exceed 141 mg/dl [unless one whacks out on sugar], and return to preprandial [before meal and/or fasting] levels [60/70 to 99 mg/dl] within 2–3 hours. HTH
this may help
