Got the message re causes of K problems.

[Guest guest]

Did not see that they mentioned some of the other rare causes of

pseudohypokalemia.

1. Severe hypertriglyceridemia.

or hyperperkalemia

1. Thrombocytosis

2. Some leukemias.

There are prob others I have forgotten.

But most common cause of pseudonormokalemia (K reading normal but

blood K is low) is blood drawing problems with hemolysis and using

tourniquet and fist pumping.
