WTF??!?!???

I'm using a PrecisionXTRA monitor (the brand I have used for years), but recently obtained a new model and new (5ul/test) strips.

Checked my bedtime BG at about 2 hr PP.

1st test = 341 ... grrrr..., especially since @ 1hr PP it was @ 255
2nd test (within 1 minute!) = 297

okay... try a third to confirm.

3rd test (again within 1 minute) = 282.

... I just dropped my BG by 59 points by testing three times!!!! .. WTF, mate?!??!

if my math serves right, that's easily +/- 10%!!!
... Do I need to check my BG three times if I want an accurate result?

FRUSTRATED

I think I read here somewhere that it could be as much as 20% one way or the other and even the food or sweets that your hand touches can give weird readings on different fingers. Wash your hands or use alcohol wipes first. Those readings are high and I really don't think 10% makes all that much of a difference.

Most meters have an error range of ±20%.

1st test = 341 @ ± 68 (277-409)
2nd test = 297 @ ± 58 (239-355)
3rd test = 282 @ ± 56 (226-338)

These are rough estimations, but as you can see, each number is either within or very close to the other 2 numbers error tolerance.
