Measuring range
The QuikRead go instrument displays the HbA1c results in mmol/mol and/or percentages
(%). The calculated estimated average glucose (eAG) can be displayed with mmol/mol
or % -results.

13 Traceability
The calibrators used to calibrate the HbA1c assay of the QuikRead go HbA1c test are
traceable to the IFCC Reference Measurement Procedure
14 Method comparison
Finger prick capillary blood and anticoagulated whole blood samples from 170 patients were
measured with the QuikRead go HbA1c method at a NPT clinical site. The reference values
were determined with an HPLC method at clinical laboratory. Summary of correlation study
is presented in Tables 4 and 5.

15 Disposal
● Dispose of contents according to national and local law.
● All patient samples and sample collectors, controls, used caps, cuvettes and tubes
should be handled and disposed of as potentially infectious material.
● Materials used in various QuikRead go kit components:
Paper: Instructions for use
Cardboard: Kit box including its inner parts and sample collector box
Plastic: Cuvettes, reagent caps, cuvette rack, plungers, plunger and capillary tubes,
filling inside capillary tube and the filling of sample collector box, swabs and extraction
vials and tubes
Glass: Capillaries
Metal: Reagent cap tubes, cuvette lids, plunger and capillary tube caps
Several (not to be recycled): Lids of reagent cap tubes, foil covering cuvette rack,
unopened cuvettes and unused sample collectors
● When used in accordance with Good Laboratory Practice, good occupational hygiene,
and the instructions for use, the reagents supplied should not present a hazard to
health.
