Order Selenium Urine Test | Deficiency TestingThe selenium urine test measures the amount of selenium excreted in urine, providing a direct indicator of recent selenium intake and body status.

This test is used both to monitor occupational exposure to selenium and to identify a deficiency when symptoms or risk factors are present.
About Selenium Urine Test | Deficiency Testing in Arcadia
Selenium is a trace mineral that the body incorporates into selenoproteins, which act as antioxidants and regulate thyroid hormone metabolism.
Selenium is obtained primarily through diet, with rich sources including Brazil nuts, seafood, meat, and eggs. Once absorbed, it is incorporated into selenoproteins such as glutathione peroxidase, which protect cells from oxidative damage. The amount of selenium excreted in urine reflects recent intake and can indicate whether a person is meeting, exceeding, or falling short of their physiological needs.
A selenium deficiency can impair antioxidant defenses and thyroid function, potentially leading to symptoms like fatigue, muscle weakness, or increased susceptibility to illness. Deficiency is more common in regions with low soil selenium, in individuals with malabsorption conditions, or in those receiving long-term parenteral nutrition without supplementation. Conversely, excessive selenium exposure—whether from supplements, contaminated water, or industrial settings—can cause selenosis, characterized by hair loss, nail brittleness, and gastrointestinal upset. Urine testing is valuable for detecting both insufficient and excessive selenium levels.
This test is typically ordered when a healthcare provider suspects a selenium deficiency based on clinical signs or dietary history, or when monitoring workers who may be exposed to selenium in industrial processes such as glass manufacturing, electronics, or pigment production. It may also be used to assess the effectiveness of selenium supplementation. Results are interpreted alongside symptoms, dietary intake, and other laboratory findings to guide appropriate clinical decisions.
