This test is usually recommended when a healthcare provider suspects a patient may be experiencing a selenium deficiency or toxicity. Signs can include fatigue, hair loss, a weakened immune system, and, in severe cases, heart issues.

The Selenium, Serum test measures the level of selenium present in your blood serum. The results can indicate whether your selenium intake is adequate or if you have a deficiency or excess of selenium.

The frequency of this test is dependent on your individual health circumstances and the advice of your healthcare provider. If you're being treated for a selenium deficiency or toxicity, this test may be conducted regularly to track your progress.

Normal values can vary among different laboratories. However, a typical range could be about 70 to 150 micrograms per liter (μg/L) for adults. Always refer to the range provided by the laboratory that conducted your test.

No specific precautions are needed for this test. However, it is always important to follow your healthcare provider's instructions when preparing for any medical test.
