Unit Code 8689:
Ferritin, Serum
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.
Draw blood in a plain, red-top tube(s) or a serum gel tube(s).
Spin down and send 0.6 mL of serum refrigerated or frozen in
plastic vial.
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.
0.5 mL
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.
Transport Temperature Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) and unacceptable transport temperature(s) are also included. The preferred transport temperature is listed first, followed by the alternate acceptable temperature (if appropriate) and lastly, the unacceptable transport temperature(s).
