Copper
An essential trace mineral whose blood level flags copper deficiency, overload, and Wilson's disease.
Consider this test if:
- Investigating fatigue, anemia, low white counts, or numbness with an unclear cause
- On long-term parenteral or enteral nutrition where copper deficiency or excess is a concern
- Working up suspected Wilson's disease or another disorder of copper metabolism, usually alongside ceruloplasmin
- History of gastric or bariatric surgery, malabsorption, or high-dose zinc intake that can lower copper
- Tracking copper status over time after a deficiency or overload has been identified
- HSA/FSA eligible
- Typical results in 2-4 days · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting is required. Recent inflammation, infection, and pregnancy (especially the third trimester) raise serum copper independent of body stores, and oral contraceptives or estrogen can do the same. High-dose zinc supplements lower copper over time. Trace-metal testing is sensitive to specimen handling, so collection uses a metal-free tube; note any copper or zinc supplements and their dose for accurate interpretation.

What this test is for
Copper is an essential trace element and a cofactor for enzymes involved in energy production, iron metabolism, connective tissue, and antioxidant defense. This serum or plasma test measures circulating copper, the standard way to check copper status and the first marker ordered when deficiency or excess is suspected. Low levels point to malabsorption, malnutrition, nephrosis, or inadequate copper in long-term tube or IV feeding, and can contribute to anemia, low white counts, and neurological symptoms; high levels appear with acute inflammation, the third trimester of pregnancy, and copper overload disorders such as Wilson's disease. Because roughly 90% of serum copper is bound to ceruloplasmin, results are usually interpreted alongside a ceruloplasmin level, and inflammation or pregnancy can raise the number independent of true copper stores.
This is the circulating-copper test for most situations. Red blood cell copper and 24-hour urine copper are used for narrower questions, with urine copper in particular helping evaluate Wilson's disease.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
