Daxor Highlights Publication Of BVA-100 Study In Journal Of The American College Of Cardiology

Daxor Corporation (NYSE:DXR), the global leader in blood volume measurement technology, today announces new data demonstrating the clinical utility of the BVA-100 blood test in postural tachycardia syndrome (POTS) published in the Journal of the American College of Cardiology from the Vanderbilt Autonomic Dysfunction Center in Nashville, TN.



The study titled "Effect of High Dietary Sodium Intake in Patients with Postural Tachycardia Syndrome," tested whether high sodium diet reduces orthostatic tachycardia (heart rate) and upright heart rate compared to low sodium diet in POTS patients and secondary, its effect on plasma volume and plasma norepinephrine. Blood volume parameters were measured with Daxor's BVA-100 diagnostic blood test; a safe, accurate and objective means to directly quantify blood volume and composition. Blood volumes were expressed as a percent deviation from the patient's ideal volumes.

The results showed that the mechanism of sodium intake directly affects intravascular blood volume as measured by the BVA-100 blood test. High dietary sodium compared to low dietary sodium increases plasma volume and decreases the heart rate supporting the recommendation to increase dietary sodium intake in POTS.

"This study shows the crucial need to identify and manage shifts in blood volume in order to guide optimal treatment and outcomes in POTS patients. Daxor's BVA-100 blood test is the proven gold standard for doing so," said Michael Feldschuh, CEO and President of Daxor Corporation. "Prior studies have shown marked heterogeneity in both total blood and red blood cell volume - both prevalent in POTS."
