Alrighty. Blood test results from yesterday are back.
When I got back from the lab, the reading I had on my own meter was 142 mg/dL.
The lab said I had 147 mg/dL, which is within the margin of error.
The A1C number Sugar Sense estimated was 6.5, actual is 7.1 (same as 4 months ago).
Not exactly what I was hoping but at least things didn't get worse.
