Selenium has both beneficial and harmful effects. Low doses of selenium are needed to maintain good health. However, exposure to high levels can cause adverse health effects. Short-term oral exposure to high concentrations of selenium may cause nausea, vomiting, and diarrhea. Chronic oral exposure to high concentrations of selenium compounds can produce a disease called selenosis. The major signs of selenosis are hair loss, nail brittleness, and neurological abnormalities (such as numbness and other odd sensations in the extremities).
This test is for anyone wanting to measure the level of selenium in their body.
It is also for employers required to carry out biological monitoring for workers potentially exposed to excess selenium.

It also strengthens the immune system by increasing antioxidant capabilities which helps the body to defend itself against free radical damage and inflammation. Natural food sources of selenium include brazil nuts, tuna and eggs.
