Answer

Recently, gene expression profiling and determination of sIL-2R alpha and sCD163 concentration in peripheral blood have been suggested as useful tools for identifying early macrophage activation syndrome in patients with SJIA. [42, 43] However, the routine use of these diagnostic techniques outside of a research context is still unavailable in most laboratories worldwide.
