Lymphocyte Proliferation to Anti-CD3/Anti-CD28 and Anti-CD3/Interleukin-2 (IL-2) by Flow Cytometry

Specimen Type Describes the specimen type needed for testing

WB Sodium Heparin

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, accepted up to 48 hours. Specimens are required to be received in the laboratory weekdays and by 4 p.m. on Friday. No weekend processing. Draw and package specimen as close to shipping time as possible.

 

Container/Tube: Green top (sodium heparin)

Specimen Volume:

<3 months: 1 mL

3 months-5 years: 3 mL

6-18 years: 5 mL

>18 years: 20 mL

Collection Instructions:

1. Send specimen is original tube. Do not aliquot.

2. Ship specimen priority overnight in an Ambient Mailer-Critical Specimens Only (Supply T668).

Additional Information:

1. Date and time of draw and ordering physician name and phone number are required.

2. For serial monitoring, we recommend that specimen draws be performed at the same time of day.

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.
