The receiver operating characteristic analysis of SI for CD63, CD193 and CD203c for the diagnosis of ABPA vs other asthmatics (UA and ASA) showed an area under the curve of 0.577, 0.317 and 0.625, respectively. The SI CD203c at a cut\u2010off of 1.2 (sensitivity 50.0%, specificity 88.9%) and the SI CD63 at a cut\u2010off of 1.3 (sensitivity 42.9%, specificity 91.7%) also had limited utility for the diagnosis
