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.
10 mL aliquot of 24 hour urine collection
3 mL aliquot of 24 hour urine collection
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.
