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 help identify a selenium deficiency when clinical signs suggest inadequate intake or impaired absorption.
About Selenium Blood Test | Deficiency Testing in Fleming Island
Selenium is an essential micronutrient, meaning the body cannot synthesize it and must obtain it from dietary sources.
Selenium is incorporated into selenoproteins, a family of enzymes that includes glutathione peroxidases and iodothyronine deiodinases. These proteins help neutralize reactive oxygen species and convert thyroid hormones into their active forms. Because selenium participates in such fundamental processes, both insufficient and excessive levels can produce measurable physiological effects.
Dietary selenium comes from foods such as Brazil nuts, seafood, organ meats, and grains, though soil content influences how much selenium a given food supplies. Deficiency is uncommon in many populations but can occur with prolonged inadequate intake, malabsorption disorders, or reliance on parenteral nutrition. Symptoms associated with low selenium include muscle weakness, fatigue, and, in severe cases, cardiomyopathy.
Excessive selenium, or selenosis, typically arises from occupational exposure or overuse of supplements. Signs may include garlic-like breath odor, hair loss, brittle nails, and gastrointestinal upset. Blood testing provides a direct measurement that clinicians use alongside the patient's history and other laboratory results to assess selenium status and guide appropriate intervention.
