The value is read alongside zinc because the two trace minerals compete for absorption.
What does low Copper mean?
Low copper can appear with heavy zinc supplementation or malabsorption.
What does high Copper mean?
High copper can appear with inflammation, pregnancy, or oestrogen treatment such as birth control pills.
