Test ID: TCAPF    
T- and B-Cell Quantitation and Lymphocyte Proliferation to Antigens Panel

‹ Back to Pediatric index

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.


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

Assessing antigen-specific T-cell responses 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 antigen responses.


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

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

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.
