There are also several commercially available rapid enteric fever diagnostics that detect immunoglobulin antibodies IgG or IgM (Table 1), which have typically has been demonstrated to have poor sensitivity and inadequate specificity \cite{Wijedoru_2017}. A multisite comparative studey showed that all commercially available Salmonella Typhi RDTs Enterocheck WB (72.7% sensitivity: 86.5% specificity). In latent class modeling, CTK IgG was found to have the highest sensitivity (79.1%), while the highest overall accuracy was observed with Enterocheck (73.8% sensitivity and 94.5% specificity). All commercially available Salmonella Typhi RDTs evaluated in the study had sensitivity and specificity values that fell below the required levels to be recommended for an accurate diagnosis.
