Inserting Vials in the Instrument
Before inserting vials from clinical specimen into the stations, visually inspect all vials for evidence
of microbial growth. Evidence of microbial growth includes dark or black blood in non-lytic Aerobic
media (the blood in ongoing non-lytic Aerobic vials will be bright red in color), hemolysis, turbidity,
and excess gas pressure (causing the vial septum to bulge outward). All such vials should be
treated as positives; they should be Gram stained and subcultured.
Before inserting platelet vials into the stations, visually inspect all vials for evidence of microbial
growth which may include excessive turbidity and/or excess gas pressure (causing the vial septum
to bulge outward). All such vials should be treated as positives; they should be Gram stained and
subcultured.
If you accidentally place a vial into a blocked station, the vial entry tone does not sound and the
barcode scanner remains off. You must remove the vial from the station and reenter it with the Vial
Entry activity. Blocked stations are not tested.
After all vials have been inspected and inserted in stations, close the drawer.
A vial presence sensor immediately senses the insertion of a vial in a station and the instrument
updates the station LED indication and the status shown on the LCD.
Once vials are placed in their stations, BD recommends that you do not move them to other
stations.
Avoid opening the drawer unnecessarily. Drawers should not remain open longer than 10 minutes.
Login
Complete instructions on entering vial, specimen, and patient data is provided in Section 4.6. You
can log in demographic data at any time you find convenient.
WARNING
VIALS SHOULD BE HANDLED WITH EXTREME CARE AT ALL
TIMES. MAKE SURE ALL VIALS ARE FULLY INSERTED INTO
THE STATIONS BEFORE CLOSING THE DRAWER.
NOTE
Good clinical practice dictates that for optimal
performance, blood culture vials should be sent to the
laboratory as soon as possible upon collection.
Delays in entering blood culture vials into
continuous-monitoring blood culture instruments may
delay or impede detection of growth.
