Summary
This study tested a new, non-invasive breathing test (CO-rebreathing) to measure red blood cell mass in people with polycythemia, a condition with too many red blood cells. The goal was to see if this simple test works as well as the standard method that uses radioactive markers. 60 adults with high red blood cell counts took part. If proven accurate, this could offer a faster, safer way to diagnose polycythemia without radiation exposure.
