Specimen Type Describes the specimen type needed for testing
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.
Collection Container/Tube: Light blue top (3.2% sodium citrate)
Submission Container/Tube: Plastic vial
Specimen Volume: 0.5 mL
Specimen Stability Information: Frozen
Whole Blood (Available to local accounts only)
Container/Tube: Light blue top (3.2% sodium citrate)
Specimen Volume: 4.5 mL
Specimen Stability Information: Ambient
Collection Instructions: Protime must be completed within 24 hours of draw time.
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.
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
