Sensitive and specific detection of Crimean-Congo Hemorrhagic Fever Virus (CCHFV)—Specific IgM and IgG antibodies in human sera using recombinant CCHFV nucleoprotein as antigen in μ-capture and IgG immune complex (IC) ELISA tests

Analysis of CCHF patient samples: Raw data (OD450 – OD620), dependence from day after onset.
(A) BLACKBOX CCHFV IgM ELISA. (B) BLACKBOX CCHFV IgG ELISA. (C) VectoCrimean-CHF-IgM ELISA. (D) VectoCrimean-CHF-IgG ELISA. Paired serum samples from 15 CCHF patients were classified according to their time point of collection (days after onset of symptoms). Filled circles indicate PCR positive serum samples. Cut-off values (represented by dotted lines) were determined by ROC analysis ((A): 0.129, (B): 0.161) or according to the manufacturer’s instructions ((C): 0.240, (D): 0.246), respectively (see S2 Fig).
