| GENERAL INFORMATION | |
|---|---|
| Expected TAT | 5 - 6 days |
| Clinical Use | The test measures the T cell responses to antigens of common infections as well as to mitogens, allowing detection of deficiencies in this arm of the immune response. Patients with primary immunodeficiency may have deficits in the acquired T-cell response. It is useful for the following types of patients: Immune deficiency, Recurrent infection, Evaluation of cell-mediated immunity and monitoring immunosuppression (e.g. Transplant patients). |
| Performing Labcorp Test Code | 831367 |
| Notes | Labcorp Test Code: 831367 (Testing performed at Viracor-Eurofins) Methodology: Peripheral blood mononuclear cells are stimulated with mitogens or antigens or left unstimulated as a negative control and incubated at 37ºC. During the incubation Brefeldin A is added, causing the interferon (IFN)-gamma to be retained inside the cell. Following the stimulation phase, cells are recovered, stained for surface markers (CD45, CD3, and CD69 and intracellular IFN-gamma, and analyzed by flow cytometry. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration. |
