I've noticed a lot of times when I get a potassium that is through the roof (usually grossly hemolyzed but I've had it come back as "no visible hemolysis" as well) I'll also get a sodium that is in the 120s. On repeat both values tend to normalize. I've started sending repeats on any chemistry that has hyperkalemia and hyponatremia. I'm curious if anyone else has noticed this phenomenon or can explain it. I've searched through pubmed and google and haven't found this mentioned anywhere else.
