TCMPF - Overview: T- and B-Cell Quantitation and Lymphocyte Proliferation to Mitogens Panel

Test Catalog

Test ID: TCMPF    
T- and B-Cell Quantitation and Lymphocyte Proliferation to Mitogens Panel

Useful For Suggests clinical disorders or settings where the test may be helpful

Assessing global T-cell function and quantitating lymphocyte subsets in a single orderable test


This panel is most helpful when evaluating patients with immunodeficiencies, where quantitative decreases in T cells can lead to reduced functional mitogen responses.


See individual test IDs for more information.

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
TBBST- and B-Cell QN by Flow CytometryYesYes
LPMGFLymphocyte Proliferation, MitogensYesYes

Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

If insufficient peripheral blood mononuclear cells (PBMCs) are isolated from the patient's sample due to low WBC counts or specimen volume received, selected dilutions or stimulants may not be tested at the discretion of the laboratory to ensure the most reliable results. Testing with 1 stimulant will always be performed. When adequate specimen is available for both stimulants to be tested, an additional test code will be reflexed and billed separately.


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. Be advised that this may change the degree of interpretation received with the report.
