Test Code MISC2MAYOFSILS Silicon, Serum


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


***Must submit one specimen per orders. Specimens cannot be shared between multiple orders.***

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.

Reference Values

Reporting limit determined each analysis.

Generally: Less than 0.05 mg/dL

Silicon concentrations are influenced by diet, especially vegetable intake.

Interpretation

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.

Performing Laboratory
