| GLIC | CD8 Immune Competence, B | Yes | Yes |
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.
Method Name
Flow Cytometry
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Specimen Type
WB Sodium HeparinWhole 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
