I confess to being somewhat surprised that reporting K on haemolysed
samples is an issue (still).
Haemolysis causes an increase in measured K which is not a true result
of the circulating K concentration so why report it?
If the (unknown) true result was 1.5 mmol/l and haemolysis gave a result
of 5.0 mmol/l what would you do? How would reporting this result help
the clinicians treating the patient?
We strive for accurate results and spend large sums of money doing QC,
why abandon the whole lot by reporting results from unsuitable samples?
