Order Selenium Blood Test | Deficiency TestingThe Selenium Blood Test | Deficiency Testing measures the concentration of selenium in the bloodstream. Selenium is a trace element that the body incorporates into selenoproteins, which function as antioxidant enzymes and support thyroid hormone metabolism. Because both insufficient and excessive selenium can affect health, this test is used to assess nutritional status or to monitor exposure in occupational settings.
About Selenium Blood Test | Deficiency Testing in Rocklin
Selenium in the blood reflects recent dietary intake and body stores, making it a useful marker for identifying deficiency or overexposure.
Selenium is obtained primarily through diet, with notable sources including Brazil nuts, seafood, organ meats, and grains. Once absorbed, it is transported in the blood and incorporated into enzymes such as glutathione peroxidase, which helps protect cells from oxidative damage.
A selenium deficiency can occur when dietary intake is persistently low or when absorption is impaired. Low levels have been associated with impaired antioxidant defense and altered thyroid function. Conversely, excessive selenium intake, whether from supplements or industrial exposure, can lead to toxicity with symptoms such as hair loss, nail changes, and gastrointestinal upset.
The blood test quantifies selenium concentration to help distinguish deficiency from excess. Results are interpreted alongside clinical history, dietary patterns, and other laboratory findings. Turnaround time for this test is typically one to three business days, and preparation follows the lab's instructions.
