Blood Glucose and Sensor Glucose: What's the Difference?

[guezuraga]

I do believe you may want to rethink the above video. A statement of it's ok, is dead wrong. If there is a 10 point difference, is it OK? Extrapolate that to 20, 30, 40, 50, 60, etc, point difference, is that still OK? Of course not. Depending on the life of the sensor, these number will vary in differences . If the variance, continues to be consistently  different,  you tell me what number that might be, then you may have a bad sensor. This is not an exact science. The finger stick is still the number of preference and is the reason why the pump will not dose on just a sensor reading.

What are the types of glucose biosensors?

"It's normal and it's Okay." You've got to be a type 1 diabetic to truly appreciate what an absurd statement that is. We are stuck trying to make extremely difficult management decisions based upon glucose readings from blood glucose meters that provide questionable bG readings with an uncertainty window of 40% or more. FDA requirements specify that 95% of readings must be within +/- 15% of lab results and that 99% of readings must be within +/- 20% of lab results. Having taken in excess of 100, 000 bG readings over the past 41 years of being a type 1 diabetic utilizing meters from half a dozen different manufacturers I can assure you that those accuracy standards are often not fulfilled in real life. As if that doesn't provide enough of a challenge we are now being required to balance an already inaccurate measuring system against an even more inaccurate instrument measuring interstitial glucose levels. While this may well be the best technology can currently offer I can assure you as a diabetic struggling day after day to control difficult to impossible bG swings it is not Okay!
