Most heterophilic or anti-sheep antibodies in the samples do not interfere with the test, as
the assay antibodies lack the Fc-part. In rare cases, interference by IgM myeloma protein
has been observed.
Antigen excess
CRP concentrations less than 1000 mg/l do not give falsely low results.
13 Traceability
The calibrators used to calibrate the CRP assay of the QuikRead go CRP test are traceable
to the ERM
-DA474 reference material.

14 Disposal
●
Dispose of contents according to national and local law.
●
All patient samples, used caps, cuvettes, capillaries and plungers should be handled
and disposed of as potentially infectious material.
●
Materials of the components:
Paper: Instructions for use
Cardboard: Kit box
Plastic: Cuvettes, reagent caps, foil covering cuvette rack, cuvette rack, plungers,
plunger and capillary tubes
Glass: Capillaries
Metal: Reagent cap tubes, cuvette lids, plunger and capillary tube caps
Several (not to be recycled): Lids of reagent cap tubes
●
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.

Corrective action
Remove the cuvette and re-insert it into the right position.
Check that the cuvette has a reagent cap and the
inner blue part of the cap is not pressed down.
Discard expired kit lot. Use a new one.
Let the cuvette warm up to room temperature (18...25ºC). Test
the same cuvette again.
Let the cuvette cool down to room temperature (18...25ºC). Test
the same cuvette again.
Test the same cuvette again. The blanking process has not
been completed or the sample may contain interfering sub-
stances. In the latter case, the test cannot be completed.
Perform a new test. There has been some problem during
reagent addition. Make sure that the cap is properly closed.
Perform a new test. If this message appears often, contact your
local distributor or call customer service.
Test the same cuvette again. If the error message appears
again, perform a new test. If the test cannot be completed at all,
the sample may contain interfering substances or be otherwise
compromised.
If the level of hematocrit in a whole blood sample is below the
hematocrit measurement range of the instrument (see Section
12), no CRP result is shown.
If the level of hematocrit in whole blood samples is above the
hematocrit measurement range of the instrument (see Section
12), no CRP result is shown.
Restart the instrument. If the error message appears again,
contact your local distributor or call customer service and give
the error code.
Contact your local distributor or call customer service and give
the error code.
Corrective action
Perform a new test. Make sure that the capillary is
completely filled. Avoid air bubbles.
Perform a new test. Make sure that the capillary is
properly filled. Wipe away any excess sample from the
outside of the capillary.
Perform a new test. Make sure that the volume is
correct by checking that the liquid surface is between
the two lines marked on the cuvette.
Perform a new test. Do not touch the clear flat
surfaces in the lower part of the cuvette.
Perform a new test. Make sure that all the reagents
are from the same kit lot.
Perform a new test. Make sure that the reagents are
stored according to the instructions for use.
Check, that the used sample volume
(20 or 12 µl) matches the set plasma/serum sample
volume on the instrument.
