Daxor Corporation is a medical device company founded in 1970 and headquartered in Oak Ridge, Tennessee, specializing in blood volume measurement technology. The company's flagship product, the BVA-100 Blood Volume Analyzer, is an FDA-cleared diagnostic system that uses indicator dilution technique with I-131 Human Serum Albumin to provide precise quantification of total blood volume, plasma volume, and red cell mass in adult patients. The BVA-100 calculates normalized hematocrit and albumin transudation rate, enabling clinicians to detect hidden fluid imbalances that indirect measures miss. Daxor also supplies Volumex diagnostic kits, the radiopharmaceutical component required for blood volume analysis procedures. The technology is designed for hospital laboratory settings and clinical departments requiring critical fluid management decisions, including heart failure, critical care, sepsis, ARDS, syncope, and surgical blood loss assessment. The system is reimbursed by both public and private payers for inpatient and outpatient use, with demonstrated clinical outcomes in reducing mortality and hospital readmissions.
