Test name:

Test number:

994

Excellian order number:

LAB994

Abbreviation:

MSO

Alternate names:

Interleukin-2 soluble receptor α
IL-2 receptor alpha
IL-2 sRalpha

Useful for:

The function of IL-2 sRα is unclear. Increased levels of IL-2 sRα in biological fluids correlate with increased T & B activation and immune system activation. Results of a number of studies suggest a correlation between levels of IL-2 sRα in serum with the onset of rejection episodes in allograft recipients.
