5.3.10 Plot Display
The Plot display enables you to generate a line graph, or plot, of the test readings of a specified
non-pending station. Both Fluorescence units and Positivity are shown on the graph.
Plot displays all test readings for a vial that are stored in the database.
The interpretation of plot graph information is not to be substituted for established laboratory
procedures for determining the final positive or negative status of a culture.
To plot a vial’s readings, select the Location field on the Culture – Vial display. In the Drawer View
display that appears, select the desired station, then select OK. You are returned to the Culture –
Vial display. Select Plot to display the plot.
You can plot vials for up to 14 days after their removal from the instrument.
You cannot access the Plot Display in an instrument that is in degraded mode.
See Figure 5-11 for a sample Plot display.
To access Plot:
• From the Culture – Patient display, select the Vial tab
• Enter a vial sequence number in the Sequence field, or select the Location field and select
a station from the Drawer View display by tapping it, then selecting OK (note that you may
plot any vial that is still in the database, provided its status is not Pending)
Plot Display Fields:
Accession
Read-only field that shows the accession number of the vial.
Sequence
Read-only field that shows the vial barcode sequence number. If the vial is Anonymous,
the value “Anonymous” is shown as the sequence number.
Last Loc(ation)
Read-only field that shows the most recent station number to which the vial was/is
assigned.
Plot readings
Fluorescence units and Positivity readings are plotted on the y-axis (vertically). Readings
are indicated by red x's and are labeled Fluorescence. Positivity is indicated by blue
squares. These readings occur every 10 minutes unless testing or communications is
interrupted (e.g., by a door opening).
The values for units shown will vary among different patients, media types, volumes of
inocula, etc.
