Why is this happening?!

Carolina

I was testing with a ReliOn these last weeks and I was passing just fine, then Kaiser switched me to the one touch verio flex so they'd get the results and the difference it's quite a lot, in one I pass and on the other one I don't... now I'm afraid they will put me on insulin

-... got a scan to measure baby and it's measuring normal.. does anybody know why this happens???? Also, another Kaiser hospital told me my limits were 95 and 140, this new dr at a different Kaiser told me her limits were 90 and 130 -.-
