Please note that the estimated processing time for each test, indicated in business days, is based on data from the past 30 days across the 13 Quest Diagnostics laboratories for each test. These estimates are intended to serve as a guide and are not guarantees. Factors such as laboratory workload, weather conditions, holidays, and the need for additional testing or maintenance can influence actual processing times. We aim to offer estimates to help you plan accordingly. Please understand that these times may vary, and processing times are not guaranteed. Thank you for choosing Ulta Lab Tests for your laboratory needs.

The Interleukin-2 Receptor, EIA test contains 1 test with 2 biomarkers.

Clinical Use
Assess T-cell activation following transplantation
Assess prognosis in patients with lymphoma
Monitor therapeutic response in patients with hairy cell leukemia

Clinical Background
Elevated levels of soluble IL-2 receptor are detected in AIDS, autoimmune diseases, sarcoidosis, and a variety of leukemias and lymphomas. In HIV-positive individuals, the IL-2 receptor level is elevated during the asymptomatic phase, as well as during persistent generalized lymphadenopathy and symptomatic phases. IL-2 receptor detection may be useful in monitoring HIV and in assessing T-cell activation following transplantation. Elevated IL-2 receptor levels may also have clinical and prognostic significance in patients with malignant lymphoma, non-Hodgkin's lymphoma, B-cell, and undifferentiated lymphomas.

Studies have suggested that IL-2 receptor levels in a broad spectrum of conditions associated with T- or B-cell immune activation offer a rapid and reliable measure of disease activity, response to therapy, and, in some cases, prognosis. Measurement of the soluble IL-2 receptor level is also helpful in assessing therapeutic response in patients with hairy cell leukemia.

Enzyme immunoassay (EIA)

Clinical Significance 

Following stimulation by antigen, IL-2R is expressed on all T cells. IL-2R is released by activated cells into the surrounding extracellular fluid. IL2-R is involved in infectious, inflammatory and autoimmune diseases, cancer, and transplantation. IL-2R Antibodies are used therapeutically.

Alternative Name(s) 

IL-2 Receptor,  CYTOKINE
