Specimen Type Describes the specimen type needed for testing
Whole Blood 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.
It is recommended that specimens arrive within 24 hours of draw. Specimens are required to be received in the laboratory weekdays and by 4 p.m. on Friday. No weekend processing. Draw and package specimens as close to shipping time as possible. Ship specimen overnight in an Ambient Mailer-Critical Specimens Only (Supply T668).
For serial monitoring, we recommend that specimen draws be performed at the same time of day.
Two separate specimens are required.
Specimen Type: EDTA whole blood
Container/Tube: Lavender top (EDTA)
Specimen Volume: 4 mL
1. Send specimen in original tube. Do not aliquot.
2. Label specimen as blood for TBBS / T- and B-Cell Quantitation by Flow Cytometry.
Additional Information: Date of draw is required.
Specimen Type: Sodium heparin whole blood
Container/Tube: Green top (sodium heparin)
Specimen Volume: 15 mL
Collection Instructions: Label specimen as blood for GLIC / CD8 T-Cell Immune Competence, Global, Blood.
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.
T- and B-Cell QN by Flow Cytometry: 1 mL
Green-top (lithium heparin) tube
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
