Selenium Blood Test | Trace Element Check
Check your selenium level and support your immune and thyroid health.
The Selenium Blood Test measures the level of selenium in your blood, a vital trace element that plays a key role in many physiological processes. This test is for anyone concerned about their nutritional status, experiencing symptoms of deficiency, or wanting to monitor selenium levels as part of a health check. It is particularly relevant for individuals with thyroid conditions, those with compromised immune function, and people following restricted diets.
Selenium is incorporated into selenoproteins, which have antioxidant properties and are involved in thyroid hormone metabolism, immune response, and reproduction. This test provides a direct measurement of serum selenium, helping to identify deficiency or excess.
Why it matters
Maintaining adequate selenium levels is important for optimal immune function, thyroid health, and protection against oxidative stress. Low levels can lead to symptoms such as fatigue, hair loss, and increased susceptibility to infections, while very high levels can be toxic. This test helps you and your doctor assess whether your selenium intake is sufficient and guides any necessary dietary or supplemental adjustments.
