Quest / Blood & Iron Markers
Copper, RBC
Copper, RBC measures the concentration of copper within red blood cells. Unlike serum copper, which reflects short-term dietary intake, the RBC copper test gives a better picture of long-term copper status at the cellular level. Copper is an essential trace mineral involved in energy production, nervous system function, immune defense, and the formation of connective tissue. It also plays a role in iron metabolism and the synthesis of hemoglobin.
