RBC Copper

The Copper RBC test measures the amount of copper stored inside your red blood cells, which gives insight into the body's general homeostasis of this essential trace element. Copper is crucial for making red blood cells and connective tissue, and helps the body absorb iron. Doctors often order this test to help diagnose or rule out mineral imbalances, particularly rare conditions like Wilson's disease, where copper accumulates excessively in organs. Conversely, it can also detect copper deficiency, which may lead to anemia or other developmental issues. Because copper metabolism is closely linked to liver function, this test is frequently used alongside other assessments like ceruloplasmin and liver function panels for a comprehensive health evaluation. Knowing your intracellular copper levels is key to understanding your metabolic health and monitoring treatment effectiveness.
