Fig. 4. Cross-reactivity (A) and interference (B) study of ALFIS cardiac troponin I assay. The x-axes represent cardiac biomarkers (A) and possible interferents (B), while the y-axis represents the recovery (%). Horizontal dotted lines indicate 100%±10% recovery (%). Values within the lines indicate nonsignificant response.
