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 (EDTA) Vacutainer plastic trace element blood collection tube (catalog #368381: T183)

Acceptable: Tan-top (lead only) Becton-Dickinson tube (T615), Becton-Dickinson Microtainer (T174), or royal blue-top Monoject trace element blood collection tube (product #8881-307022)

Specimen Volume: 1 mL

Forms: If not ordering electronically, complete, print, and send a Benign Hematology Test Request Form (T755) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/benign-hematology-test-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.
