Selenium (Blood)


This blood test measures selenium levels. Selenium is an essential trace element. It is widely recognized as a key nutrient in cancer prevention and is a crucial cofactor for the conversion of T4 to T3 in healthy thyroid function. Selenium protects genes from inflammatory disease processes such as dementia, stroke, heart disease, diabetes and asthma. Selenium plays a crucial role by helping the body detoxify naturally from heavy metals such as cadmium. Cigarettes are a significant source of cadmium exposure worldwide. Cadmium has been found in toxic levels in fertilizers, pesticides and PVC plastics. Cadmium toxicity affects the lungs, brain, kidneys and bones and may lead to problems such as fatigue, confusion, depression and cardiac arrhythmias.

Test Preparation For Optimal Results:
If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
