HelpTest ID TCIPF T- and B-Cell Quantitation and Lymphocyte Proliferation to Antigens and Mitogens Panel
Useful For
Assessing antigen-specific T-cell responses, 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 antigen and/or mitogen responses.
See individual test IDs for additional information.
Profile Information
| Test ID | Reporting Name | Available Separately | Always Performed |

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

Specimens are required to be received in the laboratory weekdays and by 4 p.m. on Friday. It is recommended that specimens arrive within 24 hours of draw. Specimens arriving on the weekend may be canceled. Draw and package specimen as close to shipping time as possible. Ship specimen overnight in an Ambient Mailer-Critical Specimens Only (T668).
Date and time of draw and ordering physician's name and phone number are required.
For serial monitoring, we recommend that specimen draws be performed at the same time of day.
Forms: If not ordering electronically, complete, print, and send a Benign Hematology Test Request Form (T755) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/benign-hematology-test-request-form.pdf)
