Using the Graphs
The best way to use the graphs is to periodically compare the levels of the
graphs to the number of ASTs you anticipate during a period. If the
disposables level is lower than the anticipated work load, install an accessory
kit before you begin (see following sections). In this way, your workflow will
not be interrupted during test card processing. When comparing the
disposables level to your work load, it is important to remember that the
graphs are APPROXIMATIONS of the actual level of disposables.
Expiration of Disposables
VITEK
®
2 is programmed to measure the amount of time that the disposables
have been in the instrument. When the specified time limit is exceeded,
VITEK
®
2 displays an error message telling you that a disposable has
expired.
The Dispenser/Pipettor Accessory Kit
If the disposables have reached a low level, or if they have expired, you need
to install a Dispenser/Pipettor Accessory Kit. The kit consists of a container of
pipette tips and a saline dispenser tube with its associated tubing. The
following two sections in this chapter describe how to install an accessory kit.
