Can I add another dimension to this debate? What about whole
blood sodium and potassium versus plasma or serum. We have
just placed blood gas analysers on PICU (P=Paediatric) which use
whole blood for sodium and potassium. In the lab we use plasma.
There are differences especially with sodium which could be
clinically significant and the literature suggests different reference
ranges. How do others deal with these two problems, if at all.
I have to say that this is another argument against POCT. After all
if you were a patient would you like your tests done by a medic or
a nurse or a state registered MLSO. I know what I would want and
what I would want for any patients. You would not let an MLSO
remove your appendix would you? Technology moves on taking us
willing and unwilling with it.
