Plasma Volume Testing

[Galixie]

Does anyone know where it is still possible to get blood volume (plasma volume) tested in the US? I'd be willing to travel, but would prefer to find something nearby. I'm in Washington state.

According to the internet, Daxor has a blood volume testing method, but I can't seem to figure out where any labs that offer it are located. I tried emailing the company almost a month ago to ask, and never got any response.

@Galixie , I gathered from titbits here and there on forums that Daxor never gained much of a foothold.

There’s a new piece of equipment just approved last year for medical use. I don’t know whether anyone in the US has bought a medical version yet, but perhaps you could email the company and ask.

The company is called Detalo Health.

I know that the non-medical version (for studies, sports science) has been used in some dysautonomia studies in the US.

The measurement technique is called CO2 rebreathing.

(Also NASA has one at the Johnson Space Center!)

Oops, that should be CO (carbon monoxide) rebreathing. You breathe in a tiny amount that acts as a tracer in the blood.

Here is an old thread on another forum with folks discussing being tested:
https://www.dinet.org/forums/topic/17219-blood-volume/

(You only need to read the first page for info on testing; the rest is talking about POTS and hypovolemia.)

I’m afraid it’s ten years old, so some of the specialists mentioned may have retired. The Cleveland Clinic does still has blood volume measurement listed on its website, which I’m sure you’ve seen.

The paper on hypovolemia and syncope that is mentioned in the thread can be found here:

It might be interesting in terms of discussing other parameters that were measured e.g. hematocrit.

Thanks.

I'm in this weird limbo currently where I'm not treating my hypovolemia while waiting for there to be some kind of test to prove the problem (which I have previously been treated for for years) actually exists. I have vague hope that a hemodynamics test done by a cardiologist might suffice. But I don't know if I'll be able to get that test done either. I haven't even had the initial appointment with a cardiologist yet.

@Galixie , I noticed that Duke University seems to have a DAXOR unit:

And this doctor treats autonomic problems at Duke so would know about low blood volume:
