It is interesting that laboratory error is at the top of the list of
causes
of spurious hyperkalaemia.
Box 1 Causes of spurious hyperkalaemia
Laboratory error
Delayed analysis
Blood collected from vein into which potassium is infused
Excessive tourniquet or repeated fist clenching
Haemolysis via small needle or traumatic venepuncture
Prolonged storage of blood
Severe leucocytosis or thrombocytosis
Uncommon genetic disorders (familial pseudohyperkalaemia)
Discuss?
Have a good weekend.
