Test Overview
Inductively Coupled Plasma/Mass Spectrometry
Detecting arsenic, cadmium, mercury, and lead exposure and toxicity in 24-hour urine specimen.
ARSENIC: 0-17 years: not established, > or =18 years: <18 mcg/24 hour;
CADMIUM: 0-17 years: not established, > or =18 years: <0.6 mcg/24 hour;
MERCURY: 0-17 years: not established, > or =18 years: <2 mcg/24 hour, Toxic concentration: >50 mcg/24 hour; The concentration at which toxicity is expressed is widely variable between patients. 50 mcg/24 hour is the lowest concentration at which toxicity is usually apparent.
LEAD: 0-17 years: not established, > or =18 years: <1 mcg/24 hour.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements
Collect 24 hour urine in a clean, plastic container with no metal cap or glued insert and no preservative. Aliquot urine into a clean, plastic container with no metal cap or glued insert and refrigerate within 4 hours of completion of collection. Record 24 hour urine volume and collection dates/times on the request form. Patient should not eat seafood for a 48 hour period prior to start of collection. Collection must take place prior to or 48 hours after administering gadolinium-containing contrast media. If the patient is an Ohio resident, complete the appropriate sections of the Ohio Lead Reporting Form and submit with the specimen.
Additional Information
Includes: Cadmium (Cd), Arsenic (As), Lead (Pb), Mercury (Hg). If arsenic concentration is 35 mcg/L or greater, then fractionation (MASFR) will be performed at an additional charge. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated. Test sent to Mayo Medical Laboratories.
