I use the Alpha Trak 2 for Lucy's BGs. I've noticed that if I obtain a reading from a small sample of her blood (an ear prick that wasn't the best but potentially might work), the number seems abnormally low for her. I'll take it again a second time with a new strip and 'normal' ear prick (within 20 seconds) and the new BG reading is completely different. It makes me concerned as to how reliable all of the others are. For example, the very small blood sample from her ear tonight read 297 (she's still an uncontrolled diabetic and on TR). Another ear prick twenty seconds later, the number is 354. This isn't the first time this has occurred - I don't have records of the other number occurrences like this, but am going to start tracking them as this is now the third time something like this has happened. Any guidance?
