Selenium Test

Selenium Blood Test - More Information

The selenium test, sometimes known as a selenium blood test, selenium lab test and selenium level test, measures the selenium blood level.

Selenium is a mineral that plays a role in metabolic processes related to antioxidants and anti-aging. In excess, selenium can be toxic and cause a selenium poisoning condition known as selenosis. Symptoms of excessive selenium levels include hair and nail loss, fatigue, and a garlic breath odor but can progress into more severe illness if not addressed. Low selenium levels, or selenium deficiency, is a rare condition that can occur from poor absorption of selenium. Some research is underway to see if low selenium blood levels have an impact on chronic medical conditions but no strong evidence has been identified yet.

To get a selenium test near you, order online and get the blood test done at a Quest Diagnostics lab. Once the selenium lab report is ready, it will be available for electronic download. As can be seen on the sample selenium lab results above, selenium blood levels are reported as a number and can be compared against the reference range provided by the lab.
