>Anders you have frightened me to death! The check
cuvette certainly checks the optical system but does
NOT check what operators may do to a sample cuvette,
or their sampling techniques for obtaining a valid
blood sample. Quality assurance should check the
PROCEDURE not just the electronics. Staff should be
trained to perform liquid QA daily, and we check
regularly that the values obtained on patients match
lab values. We had a potential critical incident where
a HemoCue was actually reading 4g/L high but the
cuvette was still giving OK results, as it was an
intermittent fault and when the cuvette check was
wrong, staff repeated it and then got a correct
result, so did not report it to the lab. I don't think
your practice covers user errors.
