Silicon, Serum
Use
The test assesses the presence of silicon in serum. Silicon is a trace element that may have importance in bone formation, and monitoring silicon levels can be significant in evaluating dietary intake, especially from vegetables. Elevated levels may be influenced by diet and environmental contamination during specimen collection.
Special Instructions
The test specifically measures silicon levels in serum and does not assess silica or silicone. It is crucial to use trace metal-free containers to avoid contamination. Specimens cannot be shared between multiple orders.
Limitations
The test is prone to potential contamination by environmental factors, especially if the specimen is not collected in certified metal-free containers. Unexpected elevated results should be verified with additional testing using a trace metal-free container to ensure accuracy. Silicon levels are also influenced by dietary intake.
