Scatter plot of studies per blood meal method (n = 49). Polymerase chain reaction (PCR), enzyme-linked immunosorbent assay (ELISA), haemagglutination inhibition test (HIT), precipitin Test (PT), gel diffusion (GD) and complement fixation test (CFT) were used. Of the 24/49 (49%) studies which utilized PCR, 1/24 (4.2%) used high-resolution melting (HRM) analysis and 1/24 (4.2%) used multiplex PCR
