Test Code: HMETUSO
Synonyms/Keywords
Ref Lab Code: 8633, Arsenic (As), As (Arsenic), Cadmium (Cd), Cd (Cadmium), Hg (Mercury), Lead (Pb), Mercury (Hg), Metals Screens, Pb (Lead), Toxicology Quantitative Screen, Metals
Specimen Requirements
Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
Urine​ ​Clean, plastic aliquot container with no metal cap or glued insert.  Plastic container, 10 mL urine tube (Supply T068) ​ ​10 mL ​ ​
Collection Processing Instructions
1. Collect urine for 24 hours.
2. No preservative.
3. See Metals Analysis-Collection and Transport in Special Instructions for complete instructions.
Trace Metals Analysis - Specimen Collection and Transport
4. Refrigerate specimen within 4 hours of completion of 24-hour collection.
Patient should not eat seafood for a 48-hour period prior to start of collection. High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either gadolinium-or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.​

Test Information
​
High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
Reference Range Information
ARSENIC
0-35 mcg/specimen
Reference values apply to all ages.
 
LEAD
0-4 mcg/specimen
Reference values apply to all ages.
 
CADMIUM
0-15 years: not established
> or =16 years: 0.0-1.3 mcg/specimen
 
MERCURY
0-15 years: not established
> or =16 years: 0-9 mcg/specimen
Toxic concentration: >50 mcg/specimen
The concentration at which toxicity is expressed is widely variable between patients. 50 mcg/specimen is the lowest concentration at which toxicity is usually apparent.
