Instructions For Use on how to prepare and perform the test. The Quo-Test Analyzer
will provide on screen instructions at each stage of performing the test. At the end
of the test the result is displayed on the screen, stored in the analyzer memory and
can be printed on to a label with the optional printer.
The Quo-Test Analyzer is calibrated by the manufacturer and there are no user-
serviceable parts.
The analyzer performs optical, electronic and mechanical checks on the test
cartridge throughout the test procedure and if a problem is detected the analyzer
stops the test and an error message is displayed on the screen. If this happens,
then consult the Troubleshooting Guide and Error Messages section of this User
Manual.
Measurement Principle
The arrangement of the two light sources and associated detectors allows the
Quo-Test Analyzer to be used as a dual channel spectrophotometer / uorimeter.
This allows the Quo-Test Analyzer to be used either to measure changes in optical
density as used in Immunoturbidimetric assays or changes in light transmission from
specic uoriphores as they interact with analytes of interest e.g. HbA1c.
