Specimen Type Describes the specimen type needed for testing

Plasma Na Cit

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 light blue-top (sodium citrate) tube(s). Spin down and send 0.5 mL citrated plasma frozen in plastic vial.

 

Note: 1) Patient's Date of Birth is required.

         2) The sample should be drawn 3 hours after injection of

             drug in order to compare to published peak levels.

  

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.
