Medical Moment: EPP Testing
This ultra-rare disease is diagnosed by testing the red blood cells for the presence of abnormally high levels of protoporphyrin. These tests need to be performed in a specialized laboratory for accurate results. The specific test to order to diagnose EPP is called “Erythrocyte Protoporphyrin” levels. There are only a select number of laboratories in the United States that can perform the complex analysis to diagnose EPP.
The labs that perform this testing correctly are:
- University of Texas Medical Branch at Galveston, Texas
- Mayo Medical Laboratories
It is recommended that these laboratories are used because they offer metal-free and zinc protoporphyrin, which is essential for diagnosis and monitoring of EPP.
