Plasma Copper
Plasma copper measures the level of copper in your blood to check if your body has the right amount of this essential mineral.

Understanding Your Results (umol/L)
Low
(< 13 umol/L)
Low plasma copper levels, known as hypocupremia, indicate a copper deficiency. This can lead to symptoms like fatigue, weakness, anaemia, decreased immune function, and neurological problems such as numbness or tingling. Causes of low copper levels include poor dietary intake, malabsorption syndromes, or genetic disorders like Menkes disease, which affects copper absorption. Identifying low copper levels is important so that steps can be taken to address the deficiency, either through dietary changes or supplements, under medical supervision.
Optimal
(13 - 22 umol/L)
Plasma copper levels within the normal range indicate that your body has an adequate amount of copper to support essential functions. This balance means that your dietary intake, absorption, and utilisation of copper are all functioning properly. It's a good sign that your body is maintaining healthy copper levels, supporting vital processes like energy production, immune function, and maintenance of healthy nerves and connective tissue.
When plasma copper levels are near the upper limit, it suggests that copper levels are higher than average but not yet excessive. This could be a result of increased copper intake or early stages of conditions affecting copper metabolism. It serves as a warning sign to monitor copper levels more closely and possibly adjust dietary intake or investigate underlying causes to prevent levels from becoming too high.
If plasma copper levels are near the lower limit, it may suggest that your body is not getting quite enough copper. This could be due to a diet low in copper-rich foods or issues with absorbing copper from your diet. While you may not experience symptoms yet, it's important to ensure you're consuming enough copper to prevent deficiency. Including foods like nuts, seeds, whole grains, and shellfish can help increase copper intake.
High
(> 22 umol/L)
If plasma copper levels are higher than normal, it may indicate an excess of copper in the body, known as hypercupremia. This could be due to overexposure to copper, such as from environmental sources or contaminated water. It may also be a sign of certain health conditions, like Wilson's disease, where the body cannot properly eliminate excess copper, leading to accumulation in organs like the liver and brain. High copper levels can cause symptoms like fatigue, abdominal pain, jaundice, and neurological issues. Detecting elevated copper levels allows for timely intervention to reduce copper levels and prevent complications.
