Order Selenium Blood Test | Deficiency TestingThe Selenium Blood Test measures the concentration of selenium in the bloodstream.

This test is used both to monitor occupational or industrial exposure to selenium and to identify a deficiency when clinical signs suggest inadequate intake or impaired absorption.
About Selenium Blood Test | Deficiency Testing in Bryan
Selenium is a micronutrient the body requires in small amounts, yet it plays an outsized role in protecting cells from oxidative damage.
Selenium is incorporated into selenoproteins, a family of enzymes that includes glutathione peroxidases and thioredoxin reductases. These enzymes help neutralize reactive oxygen species, regulate thyroid hormone activation, and support normal immune responses. Because the body cannot synthesize selenium, it must be obtained from dietary sources such as Brazil nuts, seafood, meat, and grains grown in selenium-rich soil.
A deficiency in selenium is uncommon in well-nourished populations, but it can occur in individuals with malabsorption disorders, those receiving long-term parenteral nutrition without adequate supplementation, and people living in regions where soil selenium content is low. Symptoms of deficiency may include muscle weakness, fatigue, hair loss, and impaired immune function. In severe cases, selenium deficiency has been associated with cardiomyopathy and increased susceptibility to certain infections.
On the other hand, excessive selenium intake—whether from supplements, contaminated water, or industrial exposure—can lead to selenosis, characterized by gastrointestinal upset, hair and nail brittleness, garlic-like breath odor, and neurological symptoms. The Selenium Blood Test helps clinicians assess selenium status, confirm suspected deficiency or toxicity, and monitor individuals with known occupational exposure. Results are interpreted alongside dietary history, clinical presentation, and other laboratory findings.
