Test ID: FACTO    
Acetoacetate, Serum or Plasma

Specimen Type Describes the specimen type needed for testing

Varies

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.

Submit only 1 of the following specimens:

 

Preferred:

Plasma

Draw blood in a lavender-top (EDTA) or pink-top tube(s). (Plasma gel tube is not acceptable.) Spin down and send 3 mL of EDTA plasma frozen in a plastic vial.

Note:    1. Indicate plasma on request form.

            2. Label specimen appropriately (plasma).

 

Serum

Draw blood in a plain, red-top tube(s). (Serum gel tube is not acceptable.) Spin down and send 3 mL of serum frozen in a plastic vial.

Note:    1. Indicate serum on request form.

            2. Label specimen appropriately (serum).

 

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.

1.2 mL

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

Specimens other than

Plasma, serum

EDTA, pink-top, heparin, plain red-top
