About Selenium Blood Test | Deficiency Testing in Poway
The selenium blood test is a quantitative laboratory measurement of selenium concentration in serum or whole blood.
Selenium is incorporated into selenoproteins, including glutathione peroxidases and iodothyronine deiodinases, which help neutralize oxidative stress and support thyroid hormone metabolism. Because the body cannot synthesize selenium, circulating levels reflect dietary intake, gastrointestinal absorption, and, in some cases, occupational or environmental exposure.
Clinicians order this test when a deficiency is suspected or when monitoring individuals whose work involves selenium-containing materials. Symptoms associated with low selenium status can be nonspecific and may include fatigue, muscle weakness, or changes in hair and nails, so laboratory measurement is used to confirm rather than assume a deficiency.
Results are interpreted against the laboratory's established reference interval, which can vary by method and specimen type. A single value is generally considered alongside dietary history, other nutritional markers, and clinical findings. Turnaround time is typically one to three business days, and preparation follows the lab's instructions.
