Any doctors in the NJ/NY area that test for low blood volume?

Hi, I have been disabled for a couple of years now and I have not found a doctor that knows anything about low blood volume? Would anyone be able to point me in the right direction? I am looking for a doctor that knows how to run the right tests?

You could try to find a dysautonomia specialist, although they are few and far between. Some cardiologists and electrophysiologists know about low blood volume. You could also ask your doctor if s/he is willing to test your aldosterone and/or vasopressin levels.

Have you ever checked your pulse pressure (systolic BP minus diastolic BP), especially first thing in the morning before you get out of bed? If it's very abnormal, that might get your doctor to sit up and take notice.

It might depend on your reason for wanting this information.

Most practitioners use a CBC, which checks the ratio of plasma volume to RBC volume, to check for blood volume problems. Vanderbilt dysautonomia clinic has found that hypovolemia in some dysautonomia patients often results in a proportional or nearly proportional decrease in both plasma volume and RBC volume. Therefore, a CBC would not normally reveal hypovolemia that may be occuring in some dysautonomia patients.

Thus, Vanderbilt uses the Daxor blood volume analyzer. Here is Daxor’s facility locator.
