Scientists probe why some thick blood leads to dangerous clots

This study aims to understand the relationship between blood thickness (viscosity) and the risk of complications like blood clots in people with polycythemia, a condition where the body makes too many red blood cells. Researchers will measure blood thickness and clotting factors in about 160 patients to see if thicker blood directly leads to more symptoms and complications. The goal is to gather better information to help guide future treatment decisions for this condition.
