Default Bad reading

Is there a way to delete a bad reading? This morning I tested and got a FBS of 147. I then used an alcohol swab and cleaned my finger and ran another. The FBS reading dropped to 119.

So the conclusion is the first reading was bad. It now is messing up my average.

This is on a Verio IQ meter

Check your manual. Most meters have a way to mark a reading so it won't be averaged in, but it may require you mark it before removing the strip

As David says, please RTFM. With my meter, marking the reading achieves nothing - except allowing you to identify the reading as significant in some way. It still counts it in the average. And there's no way (that I've found) to delete the reading.

That said, the average you get from your meter means very little. It's averaging fastings (probably as low as you go) with Post Prandial 1 hours (probably as high as you go?) and everything in between including the fouled up ones .

For myself, I put the data into a database and calculate my own averages based on the nature of the reading involved. A bit more work but at least I don't end up with a meaningless hybrid average.

I used the 300 test solution once, and forgot to set it as a test. I tried pulling the battery and letting it set 24 hrs with no go. Also called the manufacturer. No, I forever have a 300 on my record.

I can't imagine a manufacturer designing a blood glucose meter which permitted erasing, or otherwise fudging readings.

I decided to eat out yesterday, got a 322 forever engraved on my meter. I simply don't care . . . what I cared about is how fast can I get home and bring it down. This is one where I couldn't believe he CGM.

As I understand it using an 'alcohol' swab can falsely lower your reading on meters. You should wash and dry your hands to get the correct reading.

I seem to recall that using alcohol will, in time, also toughen your skin making tests more painful over time.

Only if you don't let the alcohol dry completely. I can't speak to toughening of the skin, because I use one single digit for all my tests . . . I have a numb thumb, and I poke through scar tissue half the time anyhow.

My meter and the hospitals were about dead on. Thy used alcohol wipe, disposable sticker, squeeze , wipe dry, squeeze again test. I'm probably still using needle from last year, wiped finger on bed gown if it looked like anything on it poked, squeezed, tested.

They were about to give me shot of insulin based on 142 they hadn't updated since 2AM. I told that was an old number. I tested a 127 before lunch and 120 an hour after. They had to use their meter and got.....120. I told them their meter is now certified.

At home I wash hands better but figured if I'd been doing nothing but laying in hospital bed all week I could be a little more lax. Every test where I checked immediately before or after them, our meters were less than 3 mg/dL difference.

It's the same for me. I have lots of scar tissue on a few of my fingers. When I test my BS, I just take a lancet and poke my finger manually. I have to go pretty deep and give it a good squeeze to draw a nice drop of blood.
