Specimen Type Describes the specimen type needed for testing
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)
Specimen Volume: 0.4 mL
1. See Trace Metals Analysis Specimen Collection and Transport in Special Instructions for complete instructions.
2. Send specimen in original tube.
1. 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.
2. If ordering the trace element blood collection tube from BD, order catalog #368381.
1. Lead/Heavy Metals Reporting Form (Supply T491) in Special Instructions
2. If not ordering electronically, complete, print, and send a General Request Form (T239) with the specimen (http://www.mayomedicallaboratories.com/media/customer-service/forms/general-request-form.pdf).
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.
