Test Procedure and Results 4-13
4.6 Using Test Results
The results calculated by the analyzer are stored in memory and printed automatically, and can be
recalled and printed later as needed. If the analyzer is connected to an external computer, the
results are automatically transmitted as soon as they are calculated. See Section 9.2, “Principles of
Operation” for the basic procedure and equations used to calculate analyte concentrations.
The figure at the right shows a typical results printout. The heading
includes information such as the test date and time, sample type,
patient identification number, reagent rotor type, rotor lot number,
operator identification number, and analyzer serial number. The test
results section is printed in multiple columns, including chemistry
name, analyte concentration, and reference range in specified units,
as shown at right.
Each rotor contains reagents to detect exposure to extreme conditions
such as temperature and humidity. The message “QC OK” is printed
on the results when results from these reagents are within the
expected ranges. Otherwise, no results are printed, and the analyzer
opens the rotor drawer.
■ Results outside the reference range are indicated in by
an asterisk (*) next to the analyte concentration.
■ Results outside the dynamic range and system range are indicated by a “less than”
symbol (<) next to the lowest value of the dynamic or system range, or a “greater
than” symbol (>) next to the highest value of the dynamic or system range. (For
example, concentrations outside Glucose dynamic range are printed as <10 or
>700 mg/dl, respectively, and concentrations outside Glucose system range are
printed as 0 or >1200 mg/dL, respectively.)
