About Selenium Blood Test | Deficiency Testing in Berkeley
The selenium blood test is a quantitative measurement used to assess selenium status or to monitor exposure.
Selenium functions largely through selenoproteins, which help neutralize oxidative stress and contribute to normal immune and thyroid function. Because the body does not manufacture selenium, circulating levels reflect dietary sources such as Brazil nuts, seafood, eggs, and grains, along with any supplementation.
Clinicians order this test when a deficiency is suspected, often in the context of prolonged poor nutrition, malabsorption, or long-term parenteral nutrition. Symptoms linked to low selenium can include muscle weakness, fatigue, and cardiac or immune concerns, though these findings are nonspecific and require laboratory confirmation.
The test is also used in occupational settings to monitor industrial exposure, since excessive selenium can produce toxicity affecting the hair, nails, gastrointestinal tract, and nervous system. Results are interpreted alongside clinical history and other laboratory findings rather than in isolation.
