Specimen Required
Patient Preparation
Diet, medication, and nutritional supplements may introduce interfering substances. Patient should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential over-the-counter medications (upon the advice of their physician). 
Collect
Royal blue (K2EDTA or Na2EDTA). 
Specimen Preparation
Transport 7 mL whole blood in the original collection tube. (Min: 0.5 mL) 
Storage/Transport Temperature
Room temperature. Also acceptable: Refrigerated. 
Unacceptable Conditions
Heparin anticoagulant. Frozen specimens. 
Remarks
 
Stability
If the specimen is drawn and stored in the appropriate container, the trace element values do not change with time. 
Reference Interval
0-6 µg/L
Interpretive Data
Blood antimony levels predominantly reflect recent exposure and are most useful in the diagnosis of acute poisoning. Blood concentrations in unexposed individuals rarely exceed 10 µg/L. The form of antimony greatly influences distribution and elimination. Trivalent antimony readily enters red blood cells, has an extended half-life on the order of weeks to months, and is eliminated predominantly through the bile. Pentavalent antimony resides in the plasma, has a relatively short half-life on the order of hours to days, and is eliminated predominantly through the kidneys. Reported symptoms after toxic antimony exposure vary based upon route of exposure, duration and antimony source and may include abdominal pain, dyspnea, nausea, vomiting, dermatitis and eye irritation. Clinical presentation is similar to that of inorganic arsenic exposure.

Compliance Statement B: This test was developed and its performance characteristics determined by ARUP Laboratories. The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Note
Elevated results from noncertified trace element-free collection tubes may be due to contamination.  Elevated concentrations of trace elements in blood should be confirmed with a second specimen collected in a tube designed for trace element determinations, such as a royal blue (K2EDTA) tube.
