173
patient id field that allows up to 16 characters to uniquely identify a patient
patient name field that allows up to 40 characters that represents the patient's name
peek window 20-minute window where a removed vial must be reentered in order to retain its
status and readings
pending vial vial that exists in the database with no Start of Protocol; such vials have never
been placed in the instrument
Positive culture accession that contains at least one positive or manual-positive vial and at least
one positive vial that is not marked as a contaminant
Positive vial vial that has triggered at least one positivity algorithm
Positive 
Anonymous vial
vial with no sequence number that has triggered at least one positivity algorithm
reading gap condition where no readings have been taken or saved for at least 40 minutes
reentry window 5-hour window during which a removed vial can be reentered in order to
continue its protocol
Related vial vials are related that have the same accession number; typically used to identify
all vials that originate from the same collected specimen
replacement 
barcode
vial sequence with a medium type of 99; a barcode designed to replace the
original vial sequence barcode if it is damaged or unreadable by the barcode
scanner
sensor in a vial, the material at the bottom of the vial is called the sensor; it contains a
dye that reacts with carbon dioxide released by organisms as a by-product of
metabolic activity; the dye modulates the amount of fluorescence emitted by
material in the sensor; the system analyzes the measured fluorescence to
determine if the culture is positive
sequence barcode to identify BD BACTEC™ culture vials; barcode value is exactly 12
digits and starts with 44; the third and fourth digits contain the medium type; the
last 8 digits identify the vial
Sequenced vial vial that has an associated sequence number (i.e. is not anonymous)
Start of Protocol date and time when the vial is first placed in the instrument; value is used to
calculate End of Protocol, Time in Protocol, and Time to Detection
station format is Instrument-RowColumn (nn-Lnn, where n is for number and L is for
letter)
