GLIC CD8 Immune Competence, B Yes Yes

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Specimen Type

WB Sodium Heparin
Whole Blood EDTA


Ordering Guidance


This test requires multiple whole blood specimens to perform all testing. If only one whole blood specimen type is received, only the testing associated with that specimen type will be performed. Be advised that this may change the degree of interpretation received with the report.



Shipping Instructions


Testing is performed Monday through Friday. Specimens not received by 4 p.m. (CST) on Friday may be canceled.

 

Collect and package specimens as close to shipping time as possible. Ship specimens overnight in an Ambient Shipping Box-Critical Specimens Only (T668) following the instructions in the mailer. It is recommended that specimens arrive within 24 hours of collection.

 

Samples arriving on the weekend and observed holidays may be canceled.



Necessary Information


Date and time of collection and ordering healthcare professional name and phone number are required.



Specimen Required


Two separate whole blood specimens, EDTA and (possibly 2 tubes) sodium heparin, are required.

For serial monitoring, it is recommended that specimens are collected at the same time of day.

Testing Algorithm

When multiple specimen types are required to perform a panel of tests, the laboratory will perform the tests for which the appropriate specimen type was received, and the laboratory will cancel those for which the appropriate specimen was not received.
