What it measures
Your body needs small amounts of copper, a mineral, to make red blood cells, use iron and keep nerves healthy. This looks at how much copper is in your blood.
Why it matters for women
Estrogen can raise copper in the blood, so levels can be higher during pregnancy or on birth control that contains estrogen, and your result is read with that in mind. Low copper is uncommon, but it can cause anemia and nerve problems, and weight-loss surgery can raise the risk.
You might check it if…
- you’ve had weight-loss surgery or trouble absorbing nutrients
- your anemia doesn’t have a clear cause
- you notice numbness, tingling or trouble with balance
- a doctor mentioned Wilson disease, a rare inherited copper condition
What your result may mean
High Copper: what it may mean
High copper may appear with inflammation, infection or pregnancy, because copper can rise along with ceruloplasmin, the protein that carries it. Oral estrogen can raise it too, so levels can be higher on birth control that contains estrogen. Wilson's disease, a rare inherited condition, can make copper build up in the liver and brain, and blood copper may be high or low with it, so a clinician may add a ceruloplasmin test, which can run low with it. Too much copper from supplements or water can cause nausea, vomiting or belly pain, and some people may have no symptoms.
Low Copper: what it may mean
Low copper may result from too much zinc from supplements, trouble absorbing nutrients (malabsorption), or rare genetic conditions such as Menkes disease. Weight-loss surgery can raise the risk. Low copper is uncommon, but it can cause anemia and nerve problems, and some people may notice tiredness, numbness, tingling or unsteady walking. Copper can run higher on estrogen, so a low level in pregnancy or on estrogen-containing birth control may stand out more. A ceruloplasmin or zinc test can add useful context.
