About Selenium Blood Test | Deficiency Testing in South San Francisco
Selenium is a trace mineral required in small amounts for normal physiology.
Selenium is incorporated into selenoproteins, which act as antioxidants and help regulate thyroid hormone activity. The body obtains selenium primarily from dietary sources such as grains, nuts, seafood, and meat.
A selenium blood test quantifies the amount of selenium circulating in the blood. It is ordered when a person has symptoms consistent with deficiency, such as muscle weakness, fatigue, or hair and nail changes, or when there is concern about excessive exposure in occupational settings.
Results are interpreted alongside clinical history and other laboratory findings. Both low and high selenium levels can have health implications, so the test is used to guide further evaluation rather than to diagnose a condition on its own.
