And as for interpreting the results - pretty straightforward in a blood volume test - it is normal or it is low.
Low blood volume is common ME It is stated as such in the International Consensus Criteria of 2011 for ME.
I got the plasma volume testing done at Royal Melbourne hospital nuclear med dept.
Any one including GP can refer a patient to Nuclear med at RMH for the test
It was bulk billed so no cost involved.
(they call it a Red Cell Mass test but it is the same thing - aka plasma volume test as it measures both at once.)
I knew low blood volume was a symptom of ME/cfs /OI/POTS etc so i insisted on having it
Glad i had it now as it explains a lot and fits in with all my symptoms
I had been taking lots of fluids beforehand - oral eclectrolytes - so somehow the fluid is not getting into the blood stream - no one has ever known why we have low blood volume that i can find but it has been stated for many years that we do.
I did stop my B 12 injections and the licorice root a week or two before the test ( both increase blood volume).
Dr Paul Cheney might be the closest to it as he went into the cardiac side a lot. He has a heart transplant himself - last time i read his stuff 3 years ago.

the results from my Red Cell Mass test which was done to measure blood volume
It was a fairly straightforward blood test over a couple of hours.
Apart from my BP dropping 20 mmHg on standing - when it was finally measured correctly - this is the first test showing anything wrong . ( edit - on and my MRI which has a some things on it that i need to get checked out)
I have low blood plasma volume - It is 2.48 litres - That is 30 mls per kg when the normal range is 40-50 mls per kg.
My whole blood volume was 4.33 litres (52 mls per kilo when normal range is 60-80 ml/kg).
............................................................
"The findings demonstrate reduced plasma volume consistent with "stress polycythemia" or dehydration."
(The polycythemia was ruled out by the haematologist.
They instruct you what to eat and drink pre-test so it's not normal dehydration.)
Whole blood volume is 4.33 l itres (52 mls per kilo when normal range is 60-80 ml/kg).
Plasma volume is 2.48 litres (30 mls per kg.............. normal range is 40-50 mls per kg).
