First seen Nov 21, 2025 · Last updated May 15, 2026 · Updated 14 times

Summary

This study looks at how thick the blood is in 160 people with polycythemia, a condition where the body makes too many red blood cells. Researchers want to see if thicker blood causes more problems like blood clots. They are not testing any new treatments, just measuring blood viscosity and comparing it to symptoms.
