Defining a Control
Introduction
The Define/Edit option allows definition of up to 100 control names. The minimum
information required to save a control definition is:
• control name
• lot number
• sample type
• one chemistry selection
• QC file number
• Mean
• Standard Deviation (SD)
In addition, the assigned mean, standard deviation (SD), and constituent code can be
defined for each chemistry in a control. Control IDs can also be assigned to a control.
Grouping Chemistries Under a Control Name
All chemistries appearing in a control definition must be of the same sample type and
have the same sample preparation. (Refer to the IMMAGE Immunochemistry
Systems
Chemistry Information Manual
for specific information.)
QC File Number
The QC file number is a number from 1-999 which is unique to a chemistry defined
within a control name. If the QC file number has already been assigned, the database
will not accept it a second time. The file number can be reused after a chemistry in a
control is deleted.
Assigned Mean and Assigned SD
For initial setup of control definitions, the mean and standard deviation (SD) values
from commercial quality control inserts may be used. When the laboratory establishes
its own mean and SD ranges, these values should be used instead of the insert values.
The mean and SD values may be edited, as data is collected for the individual
laboratory.
Each laboratory should establish its own precision parameters which more accurately
reflect individual laboratory quality control criteria.
