Glucometer Elite XL.
The Glucometer Elite XL Diabetes Care System
makes blood glucose monitoring for effective diabetes control easier than
ever. The Elite XL is simple and convenient to use - needing only the smal-
lest amount of blood. Patients can transfer data from the Elite XL memory
to the computer for smart data management. The special WinGlucofacts XL
Diabetes Management Software can be downloaded through the web site or
patients can order the software and cable from Bayer Customer Service. It's
an excellent tool for effective diabetes data organization, analysis, and mana-
gement. The Elite XL Diabetes Care System is available at most pharmacies
and some accessories can be ordered directly from Bayer.
The Elite XL model has a button for manual on/off operation and to go
back through stored readings. It stores 120 readings in memory, with date and
time taken. It has a data port to download stored readings to a computer via
an optional cable. It can delete a reading if a strip has not yet been removed.
It can designate a reading as a control before or after obtaining it.
Glucometer DEX.
The Dex is somewhat harder to use than the Elites
in that the angle at which the strip is held to the drop is less flexible. For
accurate results, the meter should be held horizontally and the blood sample
should be introduced for 1-2 s after the beep and count-down start, no longer.
An insucient fill will give a falsely lower reading, while an overfill can give
