Interleukin 2 Receptor, Soluble, Serum

Other names: Soluble IL 2R

Optimal result: 175.3 – 858.2 pg/mL

- Increased levels of the soluble IL-2Rα in biological fluids correlate with activation of T and/or B cells.

- The serum soluble interleukin 2 receptor (sIL2R) level is elevated in patients with most types of lymphoid neoplasms, and is also elevated in patients with solid tumors or reactive conditions, such as severe inflammation. [L]

- Results of a number of studies suggest a correlation of levels of IL-2Rα in serum with disease activity in autoimmune and infectious disorders as well as in transplantation rejection.

- Markedly increased IL-2sRα levels have been associated with hematologic malignancies.

- Levels of IL-2Rα correlate with tumor burden and response to therapy in numerous malignancies. 

- IL-2Rα levels can be used to predict the long-term prognosis in non-Hodgkin lymphoma patients and to assess the status of patients with HIV and acquired immunodeficiency.

Soluble Interleukin 2 receptor concentration reflects the immune activation in autoimmune diseases, neoplasms (notably lymphoproliferations), and infections.

Serum soluble interleukin-2 receptor (sIL-2R) is considered a marker of lymphocyte (T and B cell)-mediated immune activation, and elevated levels have been recognised as a biomarker for malignant lymphoma, such as non-Hodgkin’s lymphoma and adult T-cell leukaemia/lymphoma. Serum sIL-2R levels are commonly measured to evaluate the disease state and therapeutic effect, and to detect recurrence in patients with malignant lymphoma in daily practice.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
