Heavy Metals Panel 4, Urine with Reflex to Arsenic Fractionated : 0020572

Mnemonic: HY MET U4

Methodology: Inductively Coupled Plasma/Mass Spectrometry
Performed: Mon-Sat
Reported: 1-4 days
Specimen Required: Collect:  24-hour or random urine collection. Specimen must be collected in a plastic container and should be refrigerated during collection. ARUP studies indicate that refrigeration of urine alone, during and after collection, preserves specimens adequately if tested within 14 days of collection. 

Transport:  10 mL aliquot from a well-mixed collection at 2-8°C (Min: 5 mL). Submit specimen in two ARUP Trace Element-Free Transport Tubes (ARUP supply #43116).

Pediatric Collection/Transport:  5 mL aliquot from a well-mixed collection at 2-8°C. Submit specimen in an ARUP Trace Element-Free Transport Tube (ARUP supply #43116).

Remarks:  Record total volume and collection time interval on transport tube and on test request form.

Unacceptable Conditions:  Urine collected within 48 hours after administration of a gadolinium (Gd.) containing contrast media (may occur with MRI studies). Acid preserved urine.

Stability:  Ambient: 1 week;  Refrigerated (preferred): 2 weeks; Frozen: 1 year
