NOTE
The New Positive indicator remains lit until all new positive
vials are removed through the Remove Positives operation.
Instrument positive vials can be returned to the instrument for
additional testing subject to the conditions described below.
Returning Positive Vials to the Instrument for Further Testing
The system allows you to return a pulled positive vial — if the vial was originally
scanned into the instrument — for up to 3 hours after removal (or until the vial
goes out of protocol, whichever is earlier).The re-entry feature resets positivity
routines, retains previous test readings,and continues to test the vial as an ongo-
ing culture. If the vial is not returned within the 3-hour re-entry window, previ-
ous test results are discarded. If the vial was manually entered (by selecting me-
dia type), the system treats it as a new vial if it is removed and subsequently re-
entered.
The following precautions should be observed when using the vial re-entry fea-
ture. Instrument-positive vials should be subcultured and Gram stained upon
removal from the instrument. Even though a 3-hour re-entry window exists for
the return of a vial t o an ongoing status, the vial should be returned t o the
instrument as soon as possible.Vials should remain at room temperature while
they are out of the instrument.
To return a pulled positive vial to the instrument for further testing, open the
door. Press the "vial entry" soft key. Next scan the vial's barcode label. Place the
vial in the indicated station (this may differ from the original station). Previous
test results are retained only in the following circumstances:
♦
Y o u originally scanned the vial barcode when entering it in the instru-
ment.
• Y o u return the vial within the required time frame.
♦
Y o u scan the vial label to re-enter the vial.
* Y o u return the vial to the same instrument from which it was removed.
If you do not use the vial entry activity to re-enter the vial, it becomes Anony-
mous at the next test cycle, and the previous test results are removed from the
database if it is not identified within the 3-hour period.
