A warning about the Contour meters "Second-Chance"

[Aaron]

Here was the post - I didn’t say much - but @mike_g also mentions a similar issue with a “second chance” on a relion meter.

@Aaron

Last night I was without CGM because my sensor had fallen off. I felt around 3.5 (63) and was going to have some cookie but decided to test anyways. I called out 3.5 to my kids but I had a strip fill problem with the contour (got the message that said add more blood). Reading came out as 2.6 (47). I said no way - I can;t be wrong, so I retested with a giant drop of blood and I was 3.3 (59), which was pretty close to the number I called out.

Moral of the story - if you want accuracy you need to use the first drop of blood. If you don’t care it you are +/- 18 mg/dl (1 mmol/l) then go ahead and use the second chance thing.

EDIT: ok - second moral - always trust your gut feeling
