Specimen Type Describes the specimen type needed for testing

Whole blood

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.


Preferred: Royal blue-top BD Vacutainer Plus with EDTA blood collection tube (Supply T183)

Acceptable: Tan-top (lead only) BD Vacutainer Plus with EDTA blood collection tube (Supply T615) or BD Microtainer with EDTA (Supply T174) or royal blue-top Monoject trace element blood collection tube

Specimen Volume: 2 mL                           

Collection Instructions:

1. See Trace Metals Analysis Specimen Collection and Transport in Special Instructions for complete instructions.

2. Send specimen in original tube.

Additional Information:

1. Patient's date of birth is required.

2. 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.

3. If ordering the EDTA trace element Vacutainer tube from BD, order catalog #368381.

Forms: Lead/Heavy Metals Reporting Form (Supply T491) in Special Instructions

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected


Mild reject; Gross reject
