The figure at the right shows the contents of a typical results printout.
The heading of the results printout includes information such as the
reagent disc type, test date and time, sample type, patient or control ID
number, alternate ID number, gender, age, operator ID number, disc lot
number, and analyzer serial number. The test results are printed in four
columns: chemistry name, analyte concentration, reference range, and
specified units, as shown. The results printout has an adhesive backing so
it can easily be placed into the patient's file.
Each reagent disc contains reagents to detect exposure to extreme condi-
tions such as temperature and humidity. The message
on the results when results from these reagents are within the expected
ranges. Otherwise, no results are printed, and the analyzer opens the disc
drawer.

Interpreting Results
Note:
As with any diagnostic test procedure, all other test procedures — including the clinical
status of the patient — should be considered prior to final diagnosis.
Results falling outside the reference range are indicated in the results by an asterisk (
printed next to the analyte concentration.
Results falling outside the dynamic range are indicated in the results by a less-than sym-
bol (
) printed next to the lowest value of the dynamic range, or a greater-than symbol
<
(
) printed next to the highest value of the dynamic range.

For example, the dynamic range of glucose is 10–700 mg/dL. A sample concentration of
glucose below this range would be printed as
range would be printed as
reported as being below or above the value indicated.
