If you have a meter that saves your readings, or even if you don't, and you test someone else with the same meter, it can drastically change your next reading and give you a false reading. You should test more than once if you feel this is the case. You may think your sugar has dropped, and that it is in a good range, and if that is the case it could be harmful. Also, you may think it is too high and adjust your sugar, and that too can be harmful. Either way, the simple answer is Just Don't Share Your Meter.

Even if you test someone with your very own meter, always make sure that you get your A1C checked by your doctor. Sometimes I have to check someone elses blood sugar with my meter that is why it is so important to get checked by your doctor.

No one else can test on my meter. I'm on a pump, and it radios my pump with my result, then recommends the amount of insulin I get, that would be bad.

Lilmarm, I think that is good advice.

Why would testing a different person mess up your meter? I don't understand that. I know it would mess up your averages, mostly because it isn't yours. But does it actually cause "damage"?
I mean, I go to the doctor's office and they use the office meter on me and all the other diabetic patients....

I wasn't sure about that either Gabby, I do understand "sharing" messes up the average but if you log everything in writing its simple to weed out when it comes time to download. As long as you change the lancet I don't see how someone elses reading screws up the meter either though the only thing NOT changing the lancet would cause is possible cross contamination of the reading if there are traces of the other persons blood left on the lancet…right???

It has something to do with the stored numbers and the ratios'. Our doctor told us about this, and since my levels are of low blood pressure, and Jims are high, when we tried, he tested, I tested, then he tested again right after me, and the change was considerable. He has an Ascensia Breeze 2, with the ten test strips. I do not know if that makes a difference.

I agree, yes the ratio would be off if you test someone other than yourself, but it cannot change YOUR actual BG reading unless you use a contaminated lancet (one thats already been used by someone else).
The machine has no clue who the person is testing, it only reads what the blood sample tells it is in that particular sample, it cannot decide who's blood it is testing, therefore it cannot screw up (for instance) my BG just because my daughter used the meter, it can only change the overall average if there is an extra reading in there that is hers and not mine.
I can test 10min apart and never get the same exact reading every time. Your blood circulates through your body therefore your never going to hit the same exact blood flow you did on a previous test…therefore no 2 readings usually come out to the exact same number.

I have been trying to find an article that I read about this to post.

Before Laura got her own meter I used my meter to test her, I really had no choice at the time as we couldn't afford to buy her one of her own, she has the same name brand that I do now and the numbers are within 3-4 points of being the same on both meters for her. If we do get an "odd" reading we retest and I write both numbers in the log because her meter does save them and even averages them out and of course a false reading screws up the average so I note in her log book the false reading so that when her Ped Endo prints out from her meter we compare the printout to what I wrote so she knows to disregard certain readings. Her meter has also been tested against the office meter with blood from the same site and there is an 8 point difference between the 2 meters, Laura's testing lower than the one the dr. office uses. After this we did the same thing against our 2 meters at home and only got a 4 point difference. NO meter is perfectly correct but using the same meter all the time will still give a good average of what your BG readings are. I also send Laura's meter to school with her, the school has a "universal" meter for all diabetics to use at school but I would rather she use her own meter that isn't used on anyone else to keep all of her readings together on 1 meter. Originally the school asked that we bring in a spare meter to keep there for her if we didn't want to use the one everyone else does but Laura's doctor suggested we just send the meter we have always used because no 2 meters are the same even if they are the same name brand so that is what we do.
