What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weakness, or persistent health issues that don't seem to have a clear cause. It helps identify nutritional imbalances and absorption problems that could be affecting your energy levels, immune function, and overall health. Many people use this test when they suspect something is off with their nutrition or metabolism but want concrete answers about their copper status.

What's included in this test?

Copper

This test measures your serum or plasma copper levels, which are essential for numerous enzyme functions throughout your body. Copper plays a critical role in energy production, iron absorption, immune function, and maintaining healthy connective tissue. Abnormal levels can indicate nutritional deficiencies, absorption problems, or certain metabolic conditions that may be causing your symptoms.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your copper levels mean for your energy, nutrition, and overall health. These notes include personalized recommendations like dietary adjustments, supplement suggestions, or whether you should consider further testing for absorption issues. You'll also get the standard lab report and can track your copper levels over time using our trends feature to see how your nutritional interventions are working.

Who should consider getting this test?
This test is valuable for anyone experiencing unexplained fatigue or weakness that hasn't responded to typical treatments. It's especially important for people with known liver conditions, malabsorption issues, malnutrition concerns, pregnant women in their third trimester, or infants on nutritional supplementation. Those with family history of Wilson's disease or Menkes disease may also benefit from testing.
What symptoms indicate I may need this test?
Common symptoms that suggest copper imbalance include persistent fatigue, weakness, frequent infections (low immune function), anemia that doesn't improve with iron, unexplained neurological symptoms, or skin and connective tissue problems. If you have chronic digestive issues affecting nutrient absorption or liver-related symptoms, testing your copper levels can provide important insights.
How can I naturally support healthy copper levels?
Maintaining balanced copper levels starts with eating copper-rich foods like shellfish, nuts, seeds, whole grains, beans, and dark leafy greens. Avoid excessive zinc supplementation, as too much zinc can interfere with copper absorption. Supporting gut health through probiotics and addressing any digestive issues can improve nutrient absorption overall. If levels are high, reducing copper-rich foods and checking your drinking water for copper pipes may help.
What is copper and why does it matter?
Copper is an essential trace mineral that acts as a helper for many enzymes in your body. It's crucial for forming red blood cells, maintaining healthy bones and blood vessels, supporting immune function, and helping your body absorb and use iron. Your body can't make copper on its own, so you need to get it from food, and maintaining the right balance is important for overall health.
What does high copper mean?
High copper levels can occur during pregnancy (especially third trimester), acute infections or inflammation, or with certain liver conditions like primary biliary cirrhosis. In rare cases, elevated copper may indicate Wilson's disease, a genetic condition where copper builds up in organs. Your doctor will consider your symptoms and may recommend additional testing like ceruloplasmin levels to understand the cause.
What does low copper mean?
Low copper levels typically indicate nutritional deficiency, malabsorption problems (like celiac disease or chronic diarrhea), or malnutrition. It can also occur in people with kidney disease who lose protein in their urine or in rare genetic conditions like Menkes disease. Low copper can contribute to anemia, weakened immunity, and bone problems if not addressed.
How often should I retest my copper levels?
If you're being treated for copper deficiency or monitoring a known condition, your doctor will likely recommend retesting every 3-6 months until levels stabilize. For those supplementing due to deficiency, testing after 8-12 weeks can show if your approach is working. If your initial results are normal but symptoms persist, discuss with your doctor whether retesting or exploring other causes makes sense.

What this means

Your copper levels are below the optimal range, which may contribute to your fatigue, weakened immunity, or difficulty absorbing iron. While mild deficiency is fairly common, addressing it can improve your energy levels and overall health.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
