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. Abbreviations: L, low level (230 ng/L TnI); M, medium level (940 ng/L TnI); H, high level (7,500 ng/L TnI); sTnI, skeletal troponin I; cTnC, cardiac troponin C; cTnT, cardiac troponin T; CK-MB, creatinine kinase muscle brain; NT-proBNP, N-terminal pro-B type natriuretic peptide; Hb, hemoglobin; Bil, bilirubin; Glc, D-glucose; Vit.C, L-ascorbic acid; Chol, cholesterol; TG, triglyceride mixture; EDTA, ethylene-diamine-tetraacetic acid; citrate, sodium citrate.
