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 deficiency when clinical signs suggest inadequate intake or impaired absorption.
About Selenium Blood Test | Deficiency Testing in San Carlos
Selenium is a micronutrient the body requires in small amounts, and its balance matters in both directions.
Selenium is incorporated into selenoproteins, which participate in antioxidant systems and in the metabolism of thyroid hormones. Because the body does not synthesize selenium, circulating levels reflect dietary intake, absorption, and, in some settings, environmental or workplace exposure.
A blood measurement is useful when a clinician suspects either insufficiency or excess. Symptoms linked to low selenium can overlap with those of other nutritional deficiencies, so laboratory results are interpreted alongside a person's history, diet, and other relevant tests rather than in isolation.
Results may be influenced by recent supplementation, diet, and the specific laboratory method used. Reference ranges vary between laboratories, and a single value is usually considered within the context of repeat testing and clinical findings when a trend needs to be established.
