Erythrocyte and whole blood toxic element levels are good indicators of body pools of essential elements as well as the toxic elements aluminum, arsenic, cadmium, lead,* and mercury. This test is an accurate way of determining whole body status of potassium and selenium.
Whole Blood generally reflects increased or recent exposure to toxic elements. This test shows levels of cadmium, lead and mercury. Nutrient elements are measured in erythrocytes and toxic elements are measured in whole blood. One exception is selenium, which is measured in whole blood as a reliable index of selenium status.
Metal toxicity is a significant environmental health concern. A toxic load of lead, cadmium, mercury or arsenic is capable of rendering considerable damage to the brain and nervous system, particularly in children.
