Dear all
Further to my response below, I am referring to the usefulness of repeat measurements after the initial diagnosis is made and treatment initiated. Of course, an initial measurement is an essential part of management and should be routine (as recommended in all textbooks and guidelines...)
Best wishes
Ian

Subject: Re: investigation of hyponatraemia - urine testing
> Dear colleagues, we are reviewing the investigation and management of our patients with hyponatraemia. Often we receive urine samples for osmolality and sodium ? after treatment has been initiated. Can you enlighten me as to when this is clinically useful? Any references would be greatly appreciated.
Dear all
I can't point to specific references to support this, but from experience I know that sometimes the cause of hyponatraemia is unclear or multiple, and I have to initiate treatment based on my best guess as to cause. In these cases I find repeat urinary measurements useful (sometimes on a daily basis) - a clearer picture may emerge over a few days which leads to a change in treatment.
