†A131| labeled albumin tracer injection (<25 microcuries: no requirement for thyroid blockade5) is followed by 5 blood draws 5-6 minutes apart. The Daxor BVA-100 measures plasma dilution in successive samples and performs a regression analysis to arrive at the total blood volume. Institutional procedural variance drives a real-world time range of ~45-90 minutes for full results; preliminary results may be obtained in < 30 minutes.
