Test Catalog

Test Id : FSILS

Silicon, Serum

Method Name
A short description of the method used to perform the test

Inductively Coupled Plasma/Optical Emission Spectrometry (ICP/OES)

NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.


Reporting Name
Lists a shorter or abbreviated version of the Published Name for a test

Silicon, Serum

Specimen Type
Describes the specimen type validated for testing


Ordering Guidance

This test assesses the presence of Silicon and does NOT measure Silica or Silicone. Silica is silicon dioxide (SiO2), which is found in quartz and sand. Silicones are inert synthetic organosilicon compounds used in adhesives, sealants, lubricants, medical applications, insulation and cooking utensils.

Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Specimen Type: Serum

Collection Container/Tube: Plastic Royal Blue top tube (Trace metal-free; No additive)

Specimen Volume: 2 mL

Collection Instructions: Draw blood in a plastic, trace metal free, royal blue top, no additive tube(s). (Serum gel tube is not acceptable.) Promptly centrifuge and separate 2 mL into an acid washed plastic screw capped vial (T619). Ship refrigerated.

Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory

0.7 mL

Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected

Other/Tissue/Swab Glass container, Polymer gel separation tube (SST or PST)

Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included

Specimen Type Temperature Time Special Container
Serum Refrigerated (preferred) 21 days Acid Washed Plastic (MML Supply T619)
Ambient 14 days Acid Washed Plastic (MML Supply T619)
Frozen 14 days Acid Washed Plastic (MML Supply T619)

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Reporting limit determined each analysis.

Generally: Less than 0.05 mg/dL

Silicon concentrations are influenced by diet, especially vegetable intake.

Provides information to assist in interpretation of the test results

Specimens for elemental testing should be collected in certified metal-free containers. Elevated results for elemental testing may be caused by environmental contamination at the time of specimen collection and should be interpreted accordingly. It is recommended that unexpected elevated results be verified by testing another specimen in a trace metal free container.

PDF Report
Indicates whether the report includes an additional document with charts, images or other enriched information


Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

9 to 11 days

Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

2 weeks

Performing Laboratory Location
Indicates the location of the laboratory that performs the test

Test Classification
Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.

The test was developed and its performance characteristics determined by NMS Labs. It has not been cleared or approved by the U.S. Food and Drug Administration.

CPT Code Information
Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.

CPT codes are provided by the performing laboratory.
