About Selenium (urine)
What is selenium?
Selenium is an essential element for healthy bodily function. Selenium is used by the body in a variety of processes including antioxidant enzymes, thyroid function and protection from cancers. Though it is essential to have some selenium in the diet, too much selenium in the body can be toxic.
Symptoms of selenium deficiency can include dizziness, muscle weakness, nausea and heart problems. Selenium toxicity can lead to symptoms including nausea, vomiting, nail and hair loss and fatigue.
Why take the test?
This test measures the level of selenium in the urine. It is typically used to diagnose selenium toxicity or deficiency.
