Acceptance of quality control
The acceptable limits for the quality control solution are provided by the manufacture for each lot of control
solution and strip lot and are stored on the meter.
The meter will automatically detect if the quality control result is within acceptable limits and displays the
result as PASS (within acceptable limits) or FAIL (outside acceptable limits).
The meter will lockout and will not permit patient testing after a FAILED quality control test. The test must
be repeated and PASS before patient testing is permitted.
Procedure if the Quality Control Test FAILS:
Check user technique
Repeat the test
Change the strips and/or control solution and repeat the test. REMEMBER Control solutions
expire 3 months after opening.
If the result is still outside the expected range DO NOT use the Inform 11 meter. Contact the POCT team.
2. EXTERNAL QUALITY CONTROL (EQA) – Bimonthly
Blood Glucose EQA tests are run on samples whose values are unknown to the operator performing
the test.
Participation in External Quality Control is Mandatory.
The Blood Sciences department will deliver an EQA sample to each ward or department for analysis
of blood glucose. Samples should be tested as per a patient sample. Results will be automatically
downloaded into the laboratory cobas IT database.
The ward sister or diabetes link nurse should decide which members of staff (trained on the meter)
should perform the External Quality Control Test.
