Interleukin-2 Soluble Receptor α
Also known as: IL-2 sRα
Use
This test is used for the measurement of Interleukin-2 Soluble Receptor α (sIL-2Rα) levels in serum.
Special Instructions
Not provided.
Limitations
The sIL-2Rα test was developed by Labcorp and has not been cleared or approved by the FDA. It should be used in conjunction with other clinical criteria for a definitive diagnosis, as it represents only one of several markers needed to confirm certain medical conditions. Variability exists in sIL-2Rα levels due to overlaps with other inflammatory disorders, which may confound interpretations. Extremely elevated levels of sIL-2Rα are often seen in severe conditions like adult T-cell lymphoma/leukemia, but should be interpreted in context with other diagnostic information.
