Investigating elevated potassium values.(CLINICAL ISSUES)(Pseudohyperkalemia )
|
One of the most frequently asked questions regarding phlebotomy is, why are the potassiums high? The answer involves a variety of factors, which can have a significant impact on the care of a patient. When an abnormally high value exists, it frequently sets off a train of investigations looking for such severe diseases as:
* renal failure;
* adrenocortical hypofunction; and
* diabetes.
A falsely elevated potassium value (pseudohyperkalemia) discovered in a pre-surgical work-up can unnecessarily delay surgery and result in additional time in the hospital. ...
