Summary

This study looked at whether a new blood marker called EM66 can help doctors tell the difference between high blood pressure caused by rare adrenal tumors (pheochromocytoma or paraganglioma) and regular high blood pressure. Researchers measured EM66 levels in 60 adults with either these tumors or essential hypertension. The goal is to improve diagnosis and avoid unnecessary tests.
