Ordering Recommendations

Useful in the assessment of recent exposure to arsenic, mercury, and lead. For chronic exposure or the determination of arsenic species, refer to Heavy Metals Panel 4, Urine with Reflex to Arsenic Fractionation (0020572). For occupational exposure, consider Lead, Industrial, Whole Blood (0025016) and/or Cadmium Exposure Panel - OSHA (0025013).

Inpatient Approval Requirements

Approval is required for inpatient testing. Please contact the resident on chemistry at 215 980 9770 between 8-5 M-F. For urgent matters at any other time, please contact the Pathology resident on call at 215 306 0286.

Patient Preparation

Diet, medication, and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals, non-essential over-the-counter medications (upon the advice of their physician), and avoid shellfish and seafood for 48 to 72 hours.

Collection Container

Collect

Royal blue (K2EDTA) or Royal blue (NaHep).

Specimen Preparation

Transport 3 or 6 mL whole blood in the original collection tube. (Min: 0.5 mL)

Storage/Transport Temperature

Room temperature. Also acceptable: Refrigerated.

Stability (from collection to initiation)

Ambient: 1 week; Refrigerated: 1 week; Frozen: Unacceptable

Unacceptable Conditions

Specimens collected in tubes other than Royal blue (K2EDTA) or Royal blue (NaHep). Specimens transported in containers other than Royal blue (K2EDTA) or Royal blue (NaHep) or Trace Element-Free Transport Tube. Clotted specimens.

Notes

Mercury is volatile; concentration may decrease over time. If the specimen is drawn and stored in the appropriate container, the arsenic and lead values do not change with time.
