One of the most common causes for elevated potassium is fist
clenching
or pumping before or during the venipuncture. Fist pumping has been
taught to generations of medical students and phlebotomists as a
means
to make the veins more visible for venipuncture; however, it
adversely
affects the potassium.


In 1990 Don, et al, (8) presented a case that clearly demonstrated
the
harm that can occur if the potassium is falsely elevated. The patient
was a university professor whose elevated potassium led to
hospitalization with many investigations that led nowhere, because
the
potassium was, in fact, not elevated. A series of experiments were
conducted that showed fist clenching was the cause for the elevated
potassium. The source of the potassium is local release of muscle-
cell
potassium from the forearm muscles. (8) Increased potassium in the
interstitial fluid of the muscles of the forearm may increase the
blood flow to those muscles.

"Contribution of patient fist clenching on potassium has been
underestimated"


Is suboptimal phlebotomy technique impacting on potassium results for

Background: Pre-analytical problems causing pseudohyperkalaemia have
been highlighted previously. These include transit time and
temperature effects when sample collection points are geographically
widely spread. Similarly, inappropriate phlebotomy technique (in
particular, requesting patients to fist clench to facilitate
venesection) is a documented cause of pseudohyperkalaemia, but its
incidence may be impossible to establish. This study illustrates how
primary care population serum potassium data altered when local
phlebotomy clinics optimized their technique.


Methods: The effect of improving phlebotomy was studied by plotting
average monthly primary care population serum potassium data and
average percentage of samples with hyperkalaemia (5.2 mmol/L or
higher) against mean monthly temperature before and after changes in
phlebotomy practice. Only samples from primary care were included
between 2002 and 2005 inclusive.


Results: Primary care population serum potassium was inversely
related
to ambient temperature. Following the change in phlebotomy practice,
the annual percentage of results above reference range (5.2 mmol/L or
higher) was reduced from 9% to 6% and the number of results breaching
the upper telephoning threshold (5.8 mmol/L or higher) fell from 0.9%
to 0.5%.


Conclusions: Ensuring that phlebotomists were trained to avoid
facilitating venesection by requesting patients to hand grip (fist
clench), was associated with lower mean serum potassium results for
the primary care patient population and a reduced incidence of
hyperkalaemia. It is likely that the contribution of patient fist
clenching during phlebotomy to pseudohyperkalaemia has been
underestimated

Yes - your original premise is common knowledge, and has been for some time,

Have you read that link you posted?
Read it again.

It is so poorly written it's laughable.

And as for your ideas of misdiagnosis, again I'd ask you what makes you
think you are in any position to judge anyone else. By your own admission
you have absolutely no personal experience of anything medical.

Those of us who do see your theories disproved on a daily basis.
What you propose seems like a plausible idea, but simply doesn't fit the
established facts on so many levels. But then again, by your own admission,
you have no education on anything medical.


Your posts here and elsewhere achieve absolutely nothing.

The medical professionals who you simultaneously quote and despise can see
the flaws in your logic and do not take you seriously (despite giving you so
many chances).

Those who are ill soon learn to treat your posts with contempt when they see
your style of "discussion".


Get a hobby - your life would be so much more constructively employed.
