The meters do not run 100% accurate and this is cause for concern by some diabetics. Others take a more casual approach. Myself, I like to take my meter along and test my blood whenever I have labs blood draws. I record this number and check it against the lab report when I get it. My meter has been pretty close. I would suggest that you take your meter with you for your next doctor appt. and check it there and use their meter and do a different finger or perhaps the same site, just another drop of blood.
Because the public has asked for small meters that give quick results and are easy to load the companies have sacrificed accuracy for size and speed. My meter is a Prestige IQ and it's big and clunky. It uses AA batteries and takes about
25 seconds to give a reading. Not only that but I have to use a large drop of blood. The upside of this meter is that it is very accurate and the strips cost about
30ยข each.
The high readings you are getting could be from a low battery or possibly a defective strip. Humidity can affect the strips as well as how well hydrated you are, too. So there are a bunch of variables here. I would keep track and if you get a high reading, retest and see what you get, (just like you did, you smart
cookie!) Unless you get an unreasonably high retest I would probably ignore the fluke high numbers. If you get high numbers a few days in a row I would call the doctor's office for advice. Hope this helps.
