Test ID: TCAPF
T- and B-Cell Quantitation and Lymphocyte Proliferation to Antigens Panel
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.
Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
See individual test IDs.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
The appropriate age-related reference values will be provided on the report.
Interpretation
Provides information to assist in interpretation of the test results
Since the presence of lymphopenia, particularly in the T-cell compartment, can reduce the magnitude of the proliferative response to antigens, it is helpful to perform simultaneous numerical evaluation of lymphocyte subsets to aid in interpretation of the functional (proliferation) data.
See individual test IDs for additional information.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
