Special Instructions
The test has not been cleared or approved by the FDA. Selenium toxicity and deficiency must be carefully monitored, especially in patients receiving parenteral nutrition. It is crucial to collect the specimen in a royal blue-top (EDTA) tube and maintain at room temperature for accurate results.
Limitations

Factors such as specimen handling or exposure to potential contaminates can affect the accuracy of results. Clotted specimens are a cause for rejection.
