How to diagnose a meter?
 

I have a Freestyle Lite. One day the readings jumped for no apparent reason. For several days I've checked it with a second identical meter. The readings are 10 to 35 units apart with the first meter always higher. Both batches is strips pass the control solution test. Which meter is accurate?

You can take blood sugar readings, one after another, and probably never get the same reading. The best blood sugar meters on the market are still only within 10% to 20% accurate. This is just one of the many problems with having diabetes. The world of technology is still lagging for us.

I had thesame probwith my one touch mini's . I had to go to the county nurse and have her take a blood sample and we compared them .She said go with the closest comparison.

The meters are required by USA law to be no more than 20% out. USA standard is in this case adopted globally. All are abt 20% out. There are larger professional models that are slightly better. Cost 100x more.
