Copper deficiency is a rare nutritional disorder where the body lacks adequate copper to support essential functions like red blood cell formation, nerve health, and bone strength. It is caused by inadequate dietary intake, malabsorption disorders like celiac disease, excessive zinc supplementation that blocks copper absorption, or gastric bypass surgery. The Heavy Metals Panel, Random Urine is the most important test for diagnosis because it directly measures copper levels in urine to identify deficiency.

Copper deficiency is caused by several factors including inadequate dietary intake of copper-rich foods like shellfish, nuts, and organ meats, malabsorption conditions such as celiac disease or Crohn disease, and excessive zinc supplementation that interferes with copper absorption. Gastric bypass surgery is another major cause because it reduces the absorption area in the digestive tract. People taking high doses of zinc supplements for extended periods are at particular risk because zinc directly competes with copper for absorption in the intestines.
The Heavy Metals Panel, Random Urine is the most important test for copper deficiency because it directly measures copper levels excreted in urine, providing clear evidence of your body's copper status. This comprehensive test detects low copper levels that indicate insufficient copper stores, which helps explain symptoms like anemia that does not respond to iron treatment, low white blood cell counts, and bone problems. The urine test is particularly valuable because it reflects how much copper your body is retaining versus eliminating, giving your doctor critical information to guide copper supplementation treatment.
You should get tested if you experience persistent fatigue and anemia that does not improve with iron supplements, frequent infections due to low white blood cell counts, unexplained numbness or tingling in your hands and feet, or bone problems like osteoporosis at a young age. Testing is especially important if you have had gastric bypass surgery, take high-dose zinc supplements, or have digestive disorders that affect nutrient absorption. Early detection through testing allows for prompt treatment before more serious neurological complications develop.

What this means
Your mercury levels are elevated above the recommended range, which may indicate recent exposure from fish consumption, dental amalgams, or environmental sources. While not at dangerous levels, chronic elevation can contribute to neurological symptoms, fatigue, and cognitive issues over time.
Recommended actions
Avoid high-mercury fish like tuna, swordfish, and king mackerel; choose low-mercury options like salmon and sardines
Increase intake of selenium-rich foods like Brazil nuts and eggs which help protect against mercury toxicity
Stay well-hydrated and eat plenty of fiber to support natural elimination
Retest in 2-3 months after reducing exposure sources to monitor improvement
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
