Separate names with a comma.
I have been using mine for about a week. I am a type 2, insulin dependent diabetic. I count carbohydrates to calculate my insulin dosage.
I have activated the advanced insulin calculator function of the Freestyle Libre and was surprised and extremely disappointed that use of this feature requires a finger-prick test. How can Abbot make the claim that the meter eliminates the need to finger-prick when it clearly does not?
This restriction is NOT identified in their advertising or descriptive literature. The only reference to it is buried deep in the User Manual on page 56. "The calculator is only for use with fingerstick blood glucose results from the built-in meter. You cannot use the insulin calculator with Sensor glucose readings."
The issue appears to be related to the difference between "Interstitial" vs "Fingerstick blood glucose" readings. Despite the fact that Insulin Pumps work from "interstitial" measurements, Abbott precludes their use in this meter. Given the uncertainty inherent in setting carbohydrate to insulin ratios, insulin correction factors, carbohydrate intake estimates, active insulin estimates, and insulin absorption efficiency, I do not understand why the interstitial vs fingerstick readings is an issue.
While I very much like the outstanding 7/24 continuous information made available to me with this meter, I am bloody angry that I am not "allowed to chose to use" the insulin calculator capability. I am now forced back to "fingersticking" before every meal and snack.
I will now go back to using Accu-Chek Aviva Combo (or Accu-Chek Aviva Expert), both of which provide insulin calculators. I have been using the Combo for years.
Why is Abbott Laboratories allowed falsely advertise this product as Fingerstick Free?
