Investigational Use Only (IUO) flag — This tells VITEK
®
2 if an
experimental test card is being processed.
Test Card Expiration Date — This date is transferred to the workstation,
which prints it on the laboratory report.
Test Card Lot Information and Sequence Number — This includes the test
card’s lot number to provide manufacturing traceability. The sequence
number uniquely identifies a test card.
CAUTION: When handling VITEK
®
2 test cards, make sure you
do not deface the bar code in any way.
Button Memory Reader
The Button Memory Reader is a device that the VITEK
®
2 instrument uses to
read the test card information stored by the Smart Carrier Station in the
memory chip on a cassette. VITEK
®
2 uses this test card information in two
ways:
• The test card type entered at the SCS is compared to the test card type
that VITEK
®
2 reads with its own bar code reader. This ensures that no
changes were made in the position of any test card in the cassette.
• The accession ID, test card type, and the other fields entered at the SCS
are sent to the computer. This information allows the software to link the
test card results from VITEK
®
2 to patient demographic data and any
previous test results.
After the information is extracted from the button memory, VITEK
®
2 marks
its contents as Read. When the cassette is put on the SCS again, a button
memory marked as Read is erased so the cassette can be used again.
CAUTION: The memory chip must be removed from the cassette
before cleaning the cassette.
LASER WARNING
All access doors and covers must remain closed when
processing cards to avoid exposure to laser light.
