Intracellular Cytokine Panel : Viracor-IBT Laboratories

Tests included in this Panel

Cpt Code:

88184 (x1) 88185 (x11)

Clinical Utility

The assay is intended to aid in the evaluation of patients with suspected problems in lymphocyte regulation. Monitoring changes in cytokine synthesis in response to disease states or immune modulators have become an important tool in understanding basic immunological function and disease pathogenesis. Measuring the intracellular cytokine expression by the lymphocyte subpopulations CD8 and CD4 T lymphocytes, NK, and NKT cells provides a mechanism for evaluating function of these individual cell types. This information will be valuable for following immune-compromised patients or patients with graft-versus-host-disease, solid organ transplants, cancer, AIDS, sepsis, autoimmune diseases, shock and tissue injury, allergy and asthma, chronic urticaria metabolic syndrome and mood disorders.

Procedure

Whole blood is stimulated with PMA and ionomycin. Following stimulation cells are stained with antibodies to identify the cell population and cytokine of interest.
This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.

Assay Range

Reportable range is 0.1-100%. Reference ranges were established on a population of healthy adults. They should not be considered diagnositc cutoffs.

Causes For Rejection
