What is the BVA-100 Test?

The BVA-100 is an FDA-cleared diagnostic test approved to:

  • Measure intravascular total blood volume, red blood cell volume and plasma volume
  • Calculate patient-specific ideal volumes based on height, weight and gender
  • Quantify the percent deviation from the predicted ideal normal value in milliliters and as a percentage  expressing whether the patient has normal, expanded or depleted volumes
  • Report the albumin transudation rate as an indicator of capillary permeability

Dozens of published peer-reviewed studies across many medical conditions have proven the BVA-100’s unique safety, accuracy, efficacy, and value. Accurate quantification of total blood volume, plasma volume, and red blood cell volume analysis informs physicians leading to better treatment strategies and better patient outcomes.
