Anyone had the Daxor blood volume test?

@MTRJ75 What is your theory? I would be interested in hearing about it!

Easy...

1 - Low Blood Volume

2 - ???

3 - PVCs

But more seriously, dehydration seems to be one of the things that increased them for me. I'm most prone to them right before I take my Sjogren's med a couple times per day, when my throat feels the most dry. Perhaps less blood available for the heart to continuously pump correctly.

I don't know whether it is a DAXOR set-up or not, but Mayo has a reasonably detailed description of blood volume testing here:

https://my.clevelandclinic.org/health/diagnostics/16793-blood-volume-testing

It seems to have been used mostly for kidney and heart failure patients, as far as I can tell. New developments in the 80s (?) meant it was no longer needed routinely, and the machinery got old and was retired. I also saw a post from someone who used to work in nuclear medicine/testing saying that another factor was that it became harder to source the isotope.

This Mayo article states it is most often ordered for patients in intensive care.

My specialist tells me that there is nowhere that does it in Melbourne. I wonder if there might be a machine hidden away in a dusty corner of a hospital in Sydney (our largest city).

Isn't heart failure more of a blockage than volume thing? 

Last time I went to the doctor, I saw on the computer screen something about chronic kidney disease. Nobody had ever mentioned this to me, but it must be something that showed up on blood work at some point. I'm wondering if that was a blood volume thing also. I do notice there's a large difference in my bloodwork results all around when I go in after a glass or two of water an hour or so before vs not drinking anything and probably being a bit dehydrated.

They are worried about too much blood volume in heart failure. Knowing helps them to manage diuretics and stuff. The kidney disease may have been in reference to dosing a Med - many have special dosing in that case.

Dehydration can and will affect your GFR results. Meds that are processed thru your kidneys will as well. Since i got off the kidney drugs my kidneys improved. if you have heart failure your doc should know it. You will gain sudden weight and the legs generally swell up. does not mean this is not reversible (i have been put on diuretics before) just to come out of it.

Heart failure means the heart is no longer able to pump strong enough. The heart is a muscle, so it just is no longer strong enough to pump. A blockage means some of the heart (muscle) is not receiving enough blood because a vessel is blocked. Low volume means there isnt enough fluid for the heart to pump
