Specimen Type Describes the specimen type needed for testing

Plasma EDTA

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.

Forms: If not ordering electronically, complete, print, and send a Cardiovascular Test Request Form (T724) with the specimen (


Plasma and serum are required.


Specimen Type: Plasma

Collection Container/Tube: Lavender top (EDTA)

Submission Container/Tube: Plastic vial

Specimen Volume: 1 mL

Collection Instructions:

1. Fasting

2. Label specimen as plasma.


Specimen Type: Serum

Collection Container/Tube: Red top

Collection Instructions:

1. Fasting-overnight (12-14 hours)

2. Patient must not consume any alcohol for 24 hours before the specimen is drawn.

3. Label specimen as 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.

Plasma: 0.1 mL/Serum: 0.5 mL
