Abbott — Abbott optium xceed strips not available & improper reading

I am from mumbai & have been using your optium xceed glucometer, but the strips for the same are very difficult to get as many say the strips have been stopped & the last strip box purchased was 100strips minimum with very less expiry date so not able to use it completely. 25 strips still available from the last purchase but can't be used as expired.
Also the reading of the meter is not same as the lab & have observed difference of 200 units. So not sure about the meters consistency.

In this lockdown as lab are closed & with strips unavailable & improper reading i am not able to track the diabetics of my sr. Citizen parents who are on insulin & intake which need to be adjusted on the measurements.
